FIRST AMERICAN EDITIO.Y HERTFORD : PRINTED BY HALE & HOSMER I■ I » "&• i TO THE READER. Many of the members of our profession are accustom- ed to draw a distinction betwixt the knowledge obtained in classes or dissecting-rooms, and that practical know ledge which they have gained by experience; and they seem will- ing to extend this distinction in favour of themselves, by maintaining the superiority of practice over theory. There may be a defective system of education which gives too much importance to theory, but certainly the ignorance of what has been done by men of the first genius in this way, does not make the surgeon more an observer or a disci- ple of nature. Ignorance or weakness is as prone to theory as to superstition, and it requires a mind of a higher cast, strengthened by education, to subdue the natural inclination to generalize on a few limited facts. In conversing with medical men, the most remote from the Universities and practical schools of anatomy and surge- ry, I have found them indulging in the most fanciful and wild theories. No one ought to be more ready than myself to acknowledge the benefit he has derived from the conver- sation of practical men; at all times impressed with the im- portance of their information, I have cultivated their ac- quaintance with a view to improvement; but even these ve- ry men, whose chief value consists in the number of facts which they can attest from their actual observation, have always ready a theoretical interpretation which obscures the IV 10 THE READER. truth. It is not easy for a man altogether to divest him- self of this disposition, nor is it to be wished that he should; for then his lively interest in the profession would abate; but it is a propensity that requires to be chastened by edu- cation, and by acquaintance with the errors which have been committed in theoretical reasoning. In what I have now 6aid, the persons to whom I allude arc those who, indifferent to what is doing in the profession at large, over-rate their own resources, and are not fully sensible how little any individual can do in improving the general practice of medicine or surgery. Men who assume the merit of having learned all they profess from practice, and who would raise a distinction betwixt principle and ob- servation, are not aware of the extent of their admission. They confess themselves to have entered on the profession but poorly prepared; which is a great offence, since they must long have groped their way in the dark, doing mis- chief before they have learned to do good. They want the only secure foundation of experience, acquaintance with the structure of the body ; and, by entering on a high and re- sponsible duty, with a thoughtless boldness, they render even their very testimony suspicious. Ever since I became aware of the true means of improve- ment, it has been my study to seek the conversation of the elder members of the profession. In this search I may con- fidently say, that I have found their conversation pregnant with information, and their practice safe as well as bold, in the proportion of their acquaintance with anatomy. The best surgeons are, for the most part, the best men in a more extended sense; for humanity of disposition does not merely insure careful study before the duties of the profession are undertaken, but stirs on to active and virtuous exertions through a whole life. So far, therefore, from desiring to put myself in opposition to men of observation and experience, during the writing of these volume?, I have held myself as in their presence, and j confidently hope that they will receive this book favour TO TUE READER. V ably, if I shall be found to have laid the ground-work secure- ly. I propose to form a System of Operative Surgery, founded on Anatomy; and between the title of the book and the execution I hope there is a due connexion: for, if it be only in the title and preface that I have made use of anatomy, I have done nothing more than what has been done by all writers of systems. As I have built my expectation of being useful on the union of the studies of anatomy and surgery ; and as I eve- ry day see reason to believe that the neglect of surgical ana- tomy is still a common defect of education; I have felt myself as called upon at all hazards to prove the necessity of this union. It will not be denied, that there are enter- ing on the practice of the profession crowds of students who are ill provided with a knowledge of surgical anatomy ; and there are many in practice who seem never to have acknow- ledged anatomy to be a science from which the principles and the rules of practice are to be deduced. In short, I cannot help concluding, that though the higher departments of surgery are successfully cultivated by a few, there is not yet a proportionate diffusion of knowledge. Men of the first eminence have sought to obtain that rank by exerting the strength of their talents upon particular subjects; and who is there that can regret this ? But still I think I am borne out in saying, that the general subject has been in con- sequence more remissly cultivated. It has been my endeavour, throughout this work, to re- claim my reader from a loose method of considering the sub- ject ; to carry him back to the study of anatomy; to make hiin have recourse to the principles, nay, the very elements of the science. I acknowledge that in the dissecting-room the student learns the elements only ; that to let loose upon the world a young surgeon, whose education has been confined to dissection, is like arming a man bereft of reason. He is ac- customed to use the knife ; and desirous of doing it on all occasions; dexterous, perhaps, he may be, but he has not Etudicd the structure farther than it has reference to the dea,d yi TO THE READER. body ; while the acknowledged use of anatomy has reference to the living body. He can perform operations, but does not know the fit occasions for them ; nor how much the powers of life will bear ; nor how the constitution varies, and disease affects the natural powers of life. Having acknowledged thus much, I take this position in favour of anatomy, that there is no doing without it; no ad- vancing in safety one step, either in study or in practice, without its guidance. The ignorance of it makes a surgeon shy and deceitful; and what a commentary might be written on these two words ! I am in hopes that, when my reader peruses the chapters in this volume, which treat of Fractured Bones, of Dislocations, and of Wounded Arteries, he will think, that, although it be possible to cull from dissertations on the diseases which fall under the care ftf the surgeon, and from the lectures of eminent men, what might form a book having more of the external character of a system than these volumes ; it is impossible to enter on the discussion, to go to the depth of the subject for the principle of practice, without a continual reference to the structure ; and that by keeping the anatomy continually in view, the rule of practice comes out more correctly, with more simplicity and force. It is in this sense that I have ventured to call the present work a System ; for I hold a system to be distinguished more by the governing principle than by the apparent order of enumera- tion. I have to regret, that in the very first part of this volume I have not been able to speak decidedly, as to the rule of praefaee I allude to the operation of bronchotomy. I have not performed the operation , and surgeons witk whom I have conversed upon this, subject, have not, in my ODJon taken the whole circumstances into con^de atiom iToT TO THE READER. vii however, that I have explained the action of the throat and glottis, and the accidents in practice, so as to prevent the re- currence of some errors which have come to my knowledge. One thing I cannot avoid mentioning : when the patient has struggled for some time with the spasmodic difficulty of breathing, the face is swelled, and of a leaden colour ; an ap- oplectic insensibility follows ; when you raise him up, the head falls upon the shoulder; he now breathes with less diffi- culty in the throat, but if the operation be performed it will be too late ; formic difficulty of breathing through the larynx has ceased in c6n?equence of the general debility having re- solved the spasm. This debility of the muscular fibre and insensibility, has resulted from the effusion having taken place in the lungs. What I have said on the subject of the artificial pupil I wish my reader to consider as a suggestion hitherto unground- ed on the observation of the human eye. I have considered fractures and dislocations as forming the principle matter of the volume ; and before treating of them, I have thrown the subjects of abscess, and of disease of the spine and of the great joints, into short dissertations, as form- ing the best introductions to the surgery of the bones ; a sub- ject so important to the practical and military surgeon. By the liberality of my friends, and increasing opportunities of observation, even since these sheets have been printed, I have had cases and dissections which would more fully have illus- trated some part of this subject; but I am happy to say, that no circumstances have occurred, which in any degree, leave me to regret what I have said under this head. I hope the manner in which I have set forth the anatomy of the arteries will be acknowledged to be useful. For I have found students satisfied w ith repeating Murray's tables of the arteries, and by that test estimating their knowledge of this important and difficult subject. I have laboured to discountenance this idea, and to convince them that there is a minute knowledge of the arteries to which they have little turned their thoughts. It is not yel vlii 10 THE READER. four-and-twcnty hours since I have seen a remarkable exam- ple of the effects of inattention to the exact seat of arteries, as they bear reference to the superficial parts, to the nerves and tendons. To the military surgeon, the book would have been quite incomplete without this last addition of Lessons on the Arteries. losuox, 10 & 11, Leicester Street, Leicestet Square. CONTENTS OF VOLUME II.

This figure represents the lower head of the femur, with tlie capsule of tlie knee joint; the bone is suspended by the capsule; the arti- culating cartilage is destroyed, and tlie face of die bone ulcerated, in conse- quence of white swelling of the knee joint ; the capsular ligament is in part destroyed by ulceration. A, The face of the bone, rough and carious. BBB, Small portions of the articulating cartilage remaining, the rest being destroyed by ulceration. C, Part of tlie capsule suspended. D, Ulcerated holes in the capsule, by which sinuses running round the bones in the outside communicated with the cavity of the knee joint. Fi g. 2. This represents tlie thigh bone, with the head fixed and anchylos- ed in the acetabulum ischii. It is one of tiiose cases of diseased hipjoint, where the inflammation subsided in consequence of the granulation and ex- ostosis of the bone interrupting tlie motions of the joint. A, Dorsum of the ilium. B, Tuberosity of the ischium. C, Femur. D, The neck of the femur. E, The margin of the acetabulum. It may be observed, that the margin of the acetabulum is contracted and eked out, so as to enclose the head of the femur ; and even in the macerated state of the bones, though they are loose, they will not separate. F, The lesser trochanter, which has approached the pelvis so closely, whilst a granulation, has formed upon the pelvis, that the two surfaces meet- ing have formed a connexion,-by means of a ligament which checks the mo- tion of the thigh. XIV EXPLANATION PLATE II. Fig. 1. This represents the os innominatum and thigh bone destroyed by tlie hip disease. There had taken place an absorption of the bottom of the acetabulum, as well as of the head of tlie thigh bone ; so that here the neck of tlie thigh bone is represented as projecting into the pelvis. Here no anchy- losis took place, and tlie motion of the thigh bone in this unnatural position continued tlie inflammation so as at last to exhaust the patient by hectic. A, The os innominatum. B, The os pubis. C, The thigh bone. D, Tlie head, or rather only the neck, of the thigh bone, projecting into tlie cavity of the pelvis. Fig. 2. In this figure is represented the caries of the vertebrae, which pre- cedes their yielding,to the pressure of the upper part of the trunk, and the confirmed disease described under the term curvature of the spine. PLATE III. In tliis plate is represented the section of a part of the thigh bone, in the progress of union after fracture. A, The upper portion of the thigh bone. B, The lower portion of the thigh bone. C, An intermediate portion of the bone, which is in a manner isolated. D D, A tough substance, by which the bones are united, before the new bone is deposited. We may call this the callus, being a tough bed, into which the bony matter is afterwards secreted. E E, The periosteum much thickened. F F, The bony particles begun to be deposited in tlie callus. PLATE IV. Fig. 1. The fractured patella, with its ligament. A, The newly-formed ligament intermediate betwixt the portion of tlie fractured bone. B, The upper portion of the patella, which was broken off, and receded with the quadriceps muscle of die thigh. C, The lower portion oi the patella. D, The ligament by which the patella is connected with the tibia. Fig. 2. Another specimen of the fractured patella. A, The natural ligament of die patella.

XV D, The upper portion of the patella. In the case from which the first figure was taken, the portions of tlie pa- tella still lay on tiic surface of tiie tliigh bone, and playing over die head of that bone in its motion, threw die action of the tendon oft'from the centre of the joint, increasing consequendy the force of die muscle. The nearer the fractured portions of the bone are to each other, die stronger is the union betwixt them. In the second fig. the intermediate portion of new ligament is longer and proportionally weaker, and, in the next plate, the effect of diis will be seen. Plan. Fig. 3. A, The lower head of the thigh bone. B, The head of the tibia. C, The patella fractured. D, The ligament of the patella, which connects the lower fractured por- tion of the bone with the tibia. E, The muscle inserted into the upper portion of the patella. %"his plan shews that when the patella is mounted on the convex surface of the articulating head of the thigh bone, the sudden and violent action of the muscles on the thigh may 6nap it across, without the knee toucliing the ground. t Plan. Fig. 4. This-plan is designed to shew the similarity in effect of the fracture of the olecranon at die elbow joint with that of the fracture of die patella. A, The humerus. B, The ulna. C, The olecranon broken off. D, The cavity into which the point of the olecranon should enter, when the arm is distended in the natural state of the parts. If the arm be kept bent during the cure, then the space marked by the dotted line betwixt the olecranon and the ulna will be occupied by callus or new bone, and it will then be impossible to extend the arm, for before the fore arm is extended, the olecranon, C, w ill strike on die back of the hume- rus, A. We may easily understand, too, that if the arm be too much ex- tended, the ulna, B, will press the olecranon, C, out of the cavity, D ; con- sequently, after the union, the natural check to tlie extension of die arm will be lost, and there will be danger of a strain of the elbow joint, from the insufficiency of the anterior ligaments to restrain die motion backward. PLATE V. This plate represents die fore part of the knee joint torn open. It is intended to exemplify the consequences of allowing the upper portion of the patella to be drawn up by the action of the quadriceps fiemoris muscle XVi EXPLANATION OF THE rLATJEfi. This man had a fractured patella. The new ligament which was forme'd betwixt the portion of the bone incorporated with the integuments on the fore part of the joint, so far as to destroy their elasticity in a considerable degree. The man carrying a burden, slipt, and fell backward, and the knee bending under him, the ligament, and with it the integuments of the knee joint burst up, and disclosed the cavity of the joint. A A, The torn integuments. B, The articulating surface of the femur exposed. The attempt to unite the integuments failed and amputation was necessary. PLATE VI. This represents a section of the diseased nerve, spoken of in the text under the head of Tumours. A A, The tibial nerve. B B, The fibular nerve. C C, The tibial nerve enlarged into a great tumour, which occupied {jke ham. D D, The surface exposed by cutting the tumour in two parte. E, The red granulating matter which occupied cells in tlie tumour. PLATE VII. This is a slight etching of the knee joint and popliteal artery. This case is given as an example of the effect of a torn popliteal artery, as distinguish- ed from the common aneurism in this artery. A, The popliteal artery. B, The hole torn in the artery. C, The irregular projection of the shaft of the femur which tore the artery. D D, The coagulated blood condensed and united to die cellular mem- brane, so as to make an irregular sac. E, The capsule and integuments of the joint greatly dilated, in conse- quence of the aneurismal blood having been driven into the joint. F,the patella raised from the femur, in consequence of the dilatation of the cavity of the joint. G, A pencil introduced betwixt die heads of the bones, to shew the com- munication betwixt the irregular aneurism and the joint. N. B. The irregular bone which projects at C, is a consequence of a pre- vious fracture of the femur ; or rather a kind of diastasis; for, when a lad, the leg was forcibly twisted, and the apophysis of die femur broken off from the shaft of the bone. The patient was of mature years before this aneu- rism took place, from an exertion of the muscles forcing the artery against the projecting bone. I'f lar pain in the stomach, and frequent reaching with the dis- * Spasmodic affections of the oesophagus, may be removed by rubbing camphor and opium, or xther, on the sides of the neck; or by swallowing a very litde tincture of opium. Valerian and camphor may be given by the mouth or by injection. The irregularity of the uterine action, the general state of the system, and of the uterine discharges, must be attended to. When the spasm continues obstinate, the dexterous use of a bougie v$J sometimes relieve it. ITSE OF THE FLEXIBLE PIPE. IB charge of mucus collected in the oesophagus. Sometimes there is a considerable general irritation, with fits of suffoca- tion ; the voice is remarkably weak. For this complaint, as in the stricture of the urethra, the bougie and caustic are used. We sound with the bougie to ascertain if there be a confirmed stricture, and not merely a spasm or paralysis. We are to endeavour to accommodate the form and size of the bougie so as gradually to stretch the contracted part; and this failing of its effect, or being attend- ed with an increase of the mischief, we have still the use of the caustic in reserve. This practice is strongly recommended by Mr. Home. I cannot at present take the merit of making a single observation on the subject. OF THE USE OF THE FLEXIBLE PIPE, INTRODUCED INTO THE (ESOPHAGUS. It is not long since, the only means suggested to us of nour- ishing a patient who had an obstruction of deglutition, was by clysters, or by forcing down solid food into the oesophagus by the probang. It was therefore a very happy invention of Mr. Hunter, in a case of impeded action of the throat, to cover the probang with an eel-skin, which, being introduced into the stomach, enabled him to inject nourishing soups. For the same pur- pose we now use the flexible gum-tube, having adapted to it the nozzle of a syringe, or injecting bag and pipe. In the introduction of the tube, we must be careful that we do not commit a blunder, which though not likely to happen, yet because it may happen and prove fatal, we must always consider; I mean the introduction of the tube into the wind- pipe, instead of the gullet. In the first place then it is AtTong to make the patient open the mouth wide and push out the tongue, and at that instant to introduce the tube quickly, for by the projection of the tongue, the epiglottis is raised to the utmost; and if the patient should have such a command over himself, as to persevere in keeping the tongue thus, while the 14 USE OF THE FLEXIBLE PIPS. tube touches the throat, the point of the tube may pass into the glottis. On the contrary the patient should be directed to do that, which indeed he will naturally do, when he feels the tube in the fauces; let him imitate the action of swalloAving, draw back the tongue, and consequently push down the epiglot- tis : and the tube should not be passed quickly into the throat, but slowly, moving the point of it off the soft palate to the back part of the pharynx, when (being flexible) it will be di- rected into the bag of the pharynx and into the oesophagus. Yet after this precaution, and Avhen the tube is in the oeso- phagus, we pass the upper part of it through a sheet of paper, and then hold the flame of a candle to it. It has happened that in this experiment the air rushing from the tube, has shewn it to be in the trachea, and not in the oesophagus! The liquid food which is to be thrown into the stomach in this way, must be cooler than Avhat a person could take by the spoon, for it flows continually hot upon one part of the sto- mach. And I have dissected a body where I suspected a patch of inflammation, in the inner surface of the stomach, proceeded from this cause. If it should be thought necessary to keep the tube in the oesophagus for any considerable time, it must then be intro- duced through the nostril; and here it is necessary to be still more particular that the throat, be exerted, as in swallowing, in order that the tube may pass into the pharynx. There are many occasions on which the tube is to be used to convey nourishment into the stomach: for example, in young women affected with hysteria, paralytic affection of the oesophagus is not unfrequent, and they would die of this trifling complaint but for this invention. I have attended a girl who was nourished for two months in this way, the affection of the throat Avas entirely cured, but some months after she died of a complication of disease.—The oesopha- gus on dissection was quite natural. Ulcerations in the tract of the oesophagus I imagine are perpetuated and increased to a fatal degree by the perpetual irritation of the ossopha- gus in swallowing. The action itself is an excitement, and USE OF THE FLEXIBLE PIPE. 15 the matters swallowed cannot fail to lodge about the ulcer- ated surface. In this case the use of the tube will form a necessary part of the cure. The oesophagus is subject to a cancerous ulceration. It becomes hard, and irregular, and ulcerated, and the mus- cular structure of the tube being destroyed, the continuous action, by which the food is carried into the stomach, also fails, and the flexible tube is necessarily employed. Sacs are sometimes formed of the pharynx. At first, by some accidental lodging of the stones of fruit, perhaps, and afterwards by the accumulation of the food. Each meal forcing a little more into this hole or sac, it is at last enlarg- ed into a bag, which having formed by the side of the oesophagus, and being crammed with the food in the attempt to swallow, presses upon the oesophagus, and obstructs the passage into the stomach. If the flexible tube be used, the food will no longer accumulate in the lateral sac, and this sac may shrink and be obliterated. Abscesses, forming by the side of the pharynx, and open- ing into it, afterwards receive the food in the act of swallow- ing, with even a worse effect than in the last instance; this too the flexible tube may palliate or cure. When a person has attempted self-destruction by firing a pistol into his mouth, and the brain and spinal marrow and carotids have escaped, there is danger of suffocation from the inflammation and swelling of the throat, and the action of swallowing is for a long time impeded. Here the tube has been of essential service. When the attempt at suicide is made by cutting the throat, the action of swallowing impedes the cure, because the larynx is pulled up in swallowing, and by this means the union of the trachea is prevented, and even the outAvard Avound torn open; and here the flexible tube is also of great service. Itt ©F WOUNDS IN THE THROAT. OF WOUNDS OF THE THROAT. The cutting of the throat, in the attempt at suicide, is so eery common an occurrence, and requires the assistance of the surgeon so frequently, that it becomes necessary to speak of it, under a distinct head. Of all the ways of putting a period to existence, the cutting of the throat is the most dreadful, to the sane imagination. But it is the horror of the deed, on Avhich the insane wretch broods. It is the vulgar idea, that it is the cutting of the wind-pipe, not the opening of the great vessels, by Avhich the man dies. So the suicide very often cuts only on the fore part of the throat, and does not perpetrate the deed. Or not liking the experiment, or perhaps the edge of the knife strik- ing on the firm cartilage, or bone, the wound is small and the deep vessels are not touched. Sometimes he draAvs the knife across the throat, higher than the os hyoides, and then the root of the tongue, and the lin- gual artery are cut; the muscles uniting the jaAv, and os hyoides are cut; the lingual artery bleeds profusely. Per- haps the ninth pair of nerves, and the salivary ducts are wounded. The saliva and fluids attempted to be sAvalloAved, floAv from the wound. The voice is feeble and inarticulate, and there is danger of suffocation, from the- fluids and blood falling into the larynx. Sometimes he cuts down loAver than the os hyoides, and betwixt it and the thyroid cartilage, and then the epiglottis may be separated from the larynx. Speech, deglutition and respiration are difficult. When he cuts upon the thyroid cartilage, he does little harm, but when he cuts loAver down he strikes the thyroid gland, and opens its vessels. In Avhatever way the throat be cut, the bleeding is the im- mediate danger ; the person dies of hasmorrhagy or from the blood, entering the wind-pipe, and suffocating ; and the source of the blood is from the deep angle of the Avound, gene- rally the superior thyroid artery, or the lingual artery; if the carotid is touched, the patient is gone. Before the surgeon is OF RANTJLA. U called, perhaps the vessels have emptied themselves, and the faintness prevents the full jet of blood, and immediate death. The thumb is to be pressed into the angle, or a piece of sponge is thrust in by the side of the throat, until a liga- ture is throAvn over the tenaculum ; then lifting the finger from the spot from which the blood flows, one vessel will be observed to project Avith each pulsation, Avhich being taken up, other lesser branches may require to be tied. During this operation, the posture must be such as to prevent the blood falling into the trachea. When the bleeding has entirely stopt, the integuments are to be brought together by two or more stitches ; then a band- age is put about the head, and the ends of it brought doAvn from the sides of the head to a circular band round the chest, by Avhich the chin is kept down upon the breast, and the trachea and the lips of the Avound kept together. A strait jacket is now put upon the person. The food and me- dicine is to be given by the flexible tube, introduced into the gullet, if a great part of the trachea is cut across; for the motion of the throat in swalloAving, impedes the union of the Around. What proves the most distressing circumstance during the cure, (especially if the wound has been near the glottis), is the rising of inflammation, and the consequent irritation and cough. It is difficult to allay the thirst Avithout varying the position ; lying on the back for example, the patient will be able to swallow a little, or moisten the parched fauces. RANULA. Ranula is, in general, a semipellucid tumour lying under the tongue and in its commencement situate to one side of the frenulum linguae. It is described as having its origin in the obstruction of the salivary glands; and accordingly it is not confined to the seat of the sublingual gland, but appears sometimes in the cheek, in the place of the parotid duct, and then it is more fleshy and vascular. It is described as begin*- VOT.. V-. d 13 Ui RAN C LA. ning Avithout pain, the feeling of distension being alone trou- blesome. Such indeed has been the account of the patients I have seen Avith this complaint ; but I knoAv that an obstruc- tion of the salivary ducts is an extremely painful complaint, and so peculiar in the pain and distension of the salivary glands, under the tongue, upon tasting sapid food, or on the action of the muscles of the jaAV, that the patient Avould not be apt to overlook the beginning of the disease. If Ave say that Ranula is a semipellucid tumour, like a frog's belly, under the tongue, then there are tAvo kinds, the one arising from the distension of the salivary duct; the other, a simple incysted tumour. I believe they have been much confounded. If Ave define it to be a distension of the salivary ducts, then it is not always under the tongue, but is common to the other ducts. This complaint, under the tongue I have seen in an infant, and I believe it is frequent in them, from original obstruction of the duct. In adults, it is sometimes found to be complicated Avith, and to have taken its origin from salivary calculi in* the mouth of the duct. When it is in its most frequent place, under the tongue, and is alloAred to grow, it forces back the tongue, and occa- sions difficulty of swalloAving, and inarticulate speech ; and in children it prevents sucking. It Avould appear that this is sometimes a much firmer tu- mour than those I have seen, insomuch, that, by pressing forward, it has affected the teeth, and so far pressed back the tongue, as to occasion difficulty of breathing. When formed in the cheek, it has forced itself under the zigoma, and has prevented the free motion of the jaAV. The practice is, to lay these tumours freely open. Unless this be done freely, it Avill return. In its return it will often lose its transparency, and by the necessity for frequent punc- tures, it becomes a thick and fleshy bag, requiring either ex- tirpation, or escharotic and caustic dressings. Calculi form in the salivary ducts; sometimes they lodge near the mouth of the duct, without producing a tumour, and then Avith the touch of a lancet over the extremity of the OF THE SALIVARY FISTULA, 19 duct, they may be drawn out Avith forceps; or the calculus produces much irritation, and a suppurating sac is formed. After the extraction of the calculus, the injection of a slightly astringent fluid, with the syringe for fistula lacrymalis, cures it. OF THE SALIVARY FISTULA. This fistula differs essentially from other fistulous sores, connected with the natural ducts, or passages. It is not the consequence of obstruction, but of cuts upon the cheek : for it is on the cheek that they chiefly occur, from the very ex- posed situation of the duct of the parotid gland. This sore forms a fistula of a very unpleasant kind ; since while sitting at dinner, or wnen masticating, the flow of sali- va, is very profuse, and a failure of appetite, we are told, is the consequence of this discharge. I doubt the truth of this latter circumstance. If there occur a recent division of the duct, by a Avound penetrating the cheek, near its termination, Ave have only to take care that in using the twisted suture, the skin of the cheek be very accurately united, while the inside of the cut is left free, for the discharge of the saliva, from the duct, in- to the mouth. When Ave do this, the duct may chance to unite again, or though it do not, yet if the outward skin be united, the saliva a\ ill find its Avay into the mouth. The chance however is, that the case presents in the form of callous holes, discharging saliva. In which vain attempts have been made to cure the sore, by compresses, and escharo- tics. The duct may have been divided, as it passes over the masseter muscle, and of course w ithout the Avound penetrat- ing the mouth. In this case of a fistula of some continuance on the cheek, we have to establish a communication betwixt the duct, and the mouth, and then to heal the outward wound. Our first attempt Avill be, to pass a small silver probe, fiom the mouth into the natural opening of the duct, and enlarge it, if 20 OF THE DIVISION OF THE FR.ENUM LINGUA. it shall be contracted; then to substitute a small tube, which being introduced from the mouth, shall also pass some way into that part of the duct, Avhich discharges the saliva. Lastly, while the tube is retained in its place, the outward lips of the Avound are to be made raw, brought together, and healed. But the circumstances of the case may be such, that it will be better to make a hcav duct, from the fistulous open- ing into the mouth. To do this, we must push a straight needle, obliquely from the bottom of the fistula, into the mouth, and draAv through a small seaton, which is to be Avorn until the passage is callous. Then either Avith or Avithout introducing the tube, Ave have to endeavour to unite the edges of the outward opening. DIVISION OF THE FR^NUM LINGUA. There are few surgeons who have not cut the fraenulum linguae. Notwithstanding this, I venture to say that it is never absolutely necessary. There may be an expediency, when the surgeon has not weight enough with the mother to convince her that her child cannot be prevented from sucking from this cause. Sucking is effected chiefly by the motion of the lower jaw; and the tacking of the tongue even forward to the gums, will not prevent the motion ne- cessary to sucking. I doubt even whether this tying of the tongue, will impede the speech. But at the age, which has such a motive for the operation, I have less objection to it. In infancy, the consequences have been well ascertained to be suffocation from swalloAA-ing the tongue, and death from sucking, and sAvallowing the blood during sleep. To do this, or any other little operation under the tongue, an assistant having the child on his knee, puts his fingers in- to each side of the mouth, and under the tongue so that he pushes it up. With blunt pointed scissors, the surgeon cuts the membraneous part of the fraenum, taking care to avoid the larger veins, and that in the motion of the child^ OF THE TUMOUR ON THE TONGUE. ?1 he does not cut into the substance of the tongue, so as to touch the ranine arteries. ULCER AND TUMOUR ON THE TONGUE. There occurs very frequently on the tongue, an ulcer, with a foul cineritious coloured bottom. We have to exa- mine Avhether it may not have arisen in consequence of its being incessantly torn, and irritated by a spoiled and rag- ged tooth; in which case the tooth must be drawn, or filed doAvn and smoothed. But chiefly Ave must be careful to ob- serve the connection with the stomach, for I believe this to be a frequent cause of this ulcer. This will readily be be- lieved, when Ave consider the intimate sympathy betwixt the tongue, and stomach, made apparent to us on many occa- sions ; as by the state of the secretion of the tong\ie, influ- enced by the healthy and diseased action of the stomach. When neither medicine, nor diet, have influence on the ulcer of the tongue; when it becomes painful, and the edges rise and are ragged, the ulcer may be cut out, after which the tongue quickly heals. To do this the common tenaculum is introduced into the substance of the tongue, so as to pass under the ulcer. Then Avith a common scalpel, run along the convexity of the tenaculum, the diseased part together with the instrument is cut out. The tongue may be cut very freely, but let the operator be aware of the situation of the ranine arteries. When, however, the disease of the tongue is deep, when excrescences with deep roots grow upon it, or when there are small, firm tumours, formed in its substance, we adopt the means suggested to us by Mr. Home*. Ha\ing Avell examined the depth, and utmost extent of the disease, a crooked needle (draAvn to the middle of the li- gature) is passed through the substance of the tongue, be- yond the diseased part, the middle of the ligature being cut, * See his Observations on Cancer* 22 OPERATION ON THE AMYGDALiE. the needle is taken away, and the ligatures remain. There are noAv of course tAvo ligatures one of Avhich is to be tied, in each side of the diseased part, so as totally to obstruct the circulation in the insulated portion. As is here represented. A, the diseased portion ; B, B, the ligatures tied ; C, the point at which the needle was passed. In a few days the diseased part drops off, and the surface left by this separation looks sloughy, but becomes soon clean, and fills up in a Avonderful degree. The pain is much less than we should be led to expect. A salivation is some- times the effect of the operation. OPERATION ON THE AMYGDALAE. In the inflammatory sore throat, these glands sAvell enor- mously, so as to produce an apprehension of suffocation. But when they suppurate fully, they burst and the relief is perfect. In imitation of this, we have sometimes to pierce them in order to evacuate the matter. Often this does not succeed, that is to say, the matter is not fully evacuated. But shortly after the matter is spontaneously discharged. Perhaps this is, because the matter is behind the glands, or OF THE CANCERS OF THE LIP. 23 in the duplicature of the arches of the palate. Be this as it may, deep scarifications of the glands of the throat do no harm. When the tumefaction is thus great in degree, and although the matter be not evacuated, the discharge of blood relieves the sAvelling and tension. All the glandular apparatus of tlie mouth, and throat, is subject to disease; none more frequently than the amygda- lae, for often after SAvelling ennormously in their inflammatory affections, instead of entirely subsiding, or suppurating, they degenerate into hard tumours, if not scirrhosities. These tumours of the amygdala>, besides occasioning much inconve- nience, from the difficulty of sAvalloAving, produce a remarka- ble change on the voice, and require to be taken out. These diseased glands have been violently torn away, an operation not to be imitated. The French surgeons cut them Avith a concealed knife, but I conceive the ligature is still preferable. The ligature may be throAvn on the tumour, in the man- ner I have described in speaking of the operation on tu- mours in the rectum. OF THE UVULA. The uvula often hangs down relaxed, producing a feeling Avhich the patient is most anxious to be rid of. Very simple means will often succeed in causing it to be drawn up, viz. to touch it once, or tAvice, Avith a little Cayenne pepper and to use astringent gargles. When this does not succeed, and there is a real enlarge- ment, and prolapsus, the ligature, or scissors may be used to free the patient of it entirely. CANCERS OF THE LIP, &C When the lip is the seat of cancer, the disease seems to be less virulent in its nature, than when in any other part of thf body. Here excision promises perfect security. 21 OF IflL CANCERS OF THE LIP. This disease I believe is not often a true cancer but arise? from some accidental irritation, and is kept up by the inces- sant motion of the part. And this too I believe to be the rea* son why the disease is so frequent in the lower lip, and in the angle of the mouth, for the upper lip has least motion. While other remedies have been applied, I have always strong- ly recommended the use of an adhesive strap, to retain the Up, as much as possible from motion. And this fixing of the lip, is the advantage gained by poulticing those sores. My at- tention was draAvn to this circumstance, from observing that in very bad cases, some of the slighter ulcerations situated by the side of the greater diseased portion, and which could not be included in the portion cut out, healed while the pins Avere iu the lip. I haturally conceived this to arise from the per- fect repose of the lip, after the operation. I need here only state the fact, that venereal ulcers have been cut out of the lip, being mistaken for cancers, and that the disease has broke out again, and yielded to mercury. This avUI be a sufficient caution, to make us examine both the history of the disease, and the concomitant symptoms before we operate. The most frequent beginning of this cancer of the lip, is an irregular warty excrescence with a broad base, or an obscure tubercle as ithin the lip. When a sore, or disease is spreading, from such a commencement, I would not delay extirpation. The following method I prefer to the common one of using forceps. A flat piece of Avood, is shaped to go down betwixt the lip, and the gums, having a rude handle, which the as- sistant holds, at the same time that he stretches the lip upon the piece of wood, and presses it down upon its edge, so as to prevent the bleeding of the labial artery. Noav the surgeon thrusting his tenaculum or hook, into the diseased part, makes an incision on each side, down to the wood, and meeting so as to make a neat angle below, he cuts out a triangular portion of the lip, including the disease. The nicety, if there be any in this operation, consists in adapting the tAvo incisions, so that the cut surfaces may come OF THE CANCERS OF THE Lip. 25 accurately together, without puckering, or ruggedness at the lower angle. For example, if the incision of one side should be in a curv- ed direction, and the other more direct, the effect will be, that when the parts are brought together, the side Avith the curved incision is deeper than the other. Fig» 1. represents the part cut out. Fig. 2. represents the pins introduced, and the divided Hp brought together. FIG. 1. FIG. 2. The triangular piece being cut away, the assistant with- draws the piece of wood, on Avhich the incisions Avere made, and holds the two portions of the lip, betwixt his fingers and thumbs. Then bringing them together and applying the surfaces accurately to each other, the surgeon introduces his first needle, about a fifth part of an inch from the surface of the lip, and rather towards the inner part of it; the other (for tAvo are sufficient) is introduced in the middle betAvixt this and the lower part of the cut. The surgeon should noAv, put tAvo or three turns of the li- gature, about the pins, until the bleeding stops altogether. Then loosening it, he should more accurately ay ind his thread about the pins, by throwing the middle part of it over the tAvo extremities of the pin, then crossing the ends under the points, so as to form the figure of 8. Having done this Avith the upper pin, he proceeds in the same way Avith the loAver. If the disease be in the angle, or commissure of the lip?, then must there be made tAvo semilunar incisions, terminating in an acute angle on the cheek. VOL. II. E 20 OF THE CANCERS OF THE LIP. In making the tAvisted suture, the lip is more frequently too firmly braced, than not brought together sufficiently- When the ligature is draAvn to stop the bleeding, as in the first instance, and not afterwards loosened, but the operation thus finished, the SAvelling of the part makes the ligature much too tight, producing in consequence an irritation, Avhich sometimes brings on suppuration, and bursting up of the wound. But when after a short delay, which allows the bleeding to- stop, and the parts which are in some degree already swollen, are brought accurately "together. I have always found the operation succeed better, and Avithout deformity. When a great part of the lip is taken aAvay, and when the surfaces meet Avith difficulty, there is a straining on the pins, and a consequent fretting of the Avound. This is another cause of failure. It may be often prevented, by carrying an adhesive strap, from cheek to cheek, and bringing it over the lip betwixt the pins, or perhaps nearer the chin, so as to sup- port the pins, but chiefly to act as a monitor, and to check the > unwary motion of the lips. The Avound should be kept dry, and if possible Avithout motion, that a scab may be formed. If a little matter should form, Ave are not to throAv the parts loose, but let it out, Avith tlie point of a fine needle, and still retain the parts in contact. On the fourth day, I take out the loAvermost pin, (alloAving the threads to remain if they Avill) first carefully Avashing the pin with a camel's hair pencil, and clearing it of the adhering hard mucus, or blood. When the pin is withdraAvn, Avithout the point being previously cleaned, it comes through with pain, and difficulty, and may even tear the new adhesions. After a slight suppuration has loosened the pins, they should not be alloAved to remain, for they are in danger of deforming the lip. There occur incysted tumours of the fleshy part of the lip, which nothing but the knife will remove. I have taken them out by dissection, rather than as the cancerous lip is cut. Stretching the lip over the finger of an assistant, and ex OF THE HARELIP. 2.; posing its inner surface, we can dissect out the tumour, with out cutting its sac, and here as Avell as in accidental cuts of the lip, the edges will be best brought together by ligature. OF THE HARELIP. The operation for the harelip, is the same Avith that jusi described, only that in some instances the irregularity of the cleft lip, requires a more peculiar nicety in adapting the in- cision, so as afterwards to bring the parts accurately together. Of the simple cleft av e need say nothing further, than that the edges of it are to be pared off, Avith an uniform, firm in- cision, and then to be brought together, as Ave have described in the case of cancer.' We first separate the lip from the gums, if they are adhering, then we may either cut the lip on a piece of wood, put in betAvixt the lip and gums, or use the harelip-forceps, to hold the lip Avhile the edge is cut off. In this form of the disease also, there can be but one Avay of operating, although it is sometimes performed Avith dif- ficulty. The patient's head rests on the assistant's breast. The sur- geon separates the lip from the gum, if it be necessary, then takes hold of the lip, of one side, Avith the harelip-forceps, leaving out from under their edge, Avhat he means to cut off, and Avith one motion of the scalpel he cuts this portion off— Then moving his instrument to the other side, he places it so, that he may pare off the edge of that also, and bring the ter- mination of the cut accurately up, so as to form an angle Avith the first. 28 ABSCESS OF THE FRONTAL SINUS. Tlie disadA-antage of the harelip-forceps is, that they do not take a firm hold of the lip. They grasp unequally, and Avhen the incision is but half performed, the lip is apt to slip from them—Sometimes the dryness of the lip in the first cut, gives a firm hold, while in the second, the forceps or lip, be- ing bloody, they slip. The pins are introduced as in the instance of cancerous lip, and the precautions are of course the same. The operation may be done as successfully in an infant, as at the age of 14 years. Sometimes the fissure of the lip is accompanied with a cleft in the palate, and a deficiency of the bones. When part of the maxillary bone stands projecting out of its place, it may in young subjects be violently pressed doAvn, and made to ad- here in its proper place. The deficiency of the palate will diminish, as the child advances in years. On examining the bones of the face of children, with a cleft palate, I have found that the diminutiveness of the upper maxillary bone of the one side, Avas more apparent than real. The fissure is oAving to the bone of one side, being thrust laterally, and of course made also to project somewhat. If this centre piece of the palate project irregularly, I have said it may be broken down, and forced into its place. But if the jaAv-bone of one side be only pushed laterally, Avhich is the most common kind of deformity, then I imagine by a compress operated upon, by an elastic steel bandage, coming round the head, the bones may be gradually brought into their places, so as to fill up the fissure of the palate. The cure may then be completed, by the usual operation on the cleft of the lips. Or the operation being done on the lip, the after treatment will be, to bring the pieces of the superior maxillary bone together. ABSCESS IN TIIL FRONTAL AND MAXILLARY SINUS. The sinuses both of the frontal bone, and the superior max- illary bone, are subject to disease. The membrane of these abscess of the frontal sinus. 29 passages, always acutely sensible and subject to inflammation, becomes either from such general inflammation as Ave see iu catarrh, or from injuries, or the neighbourhood of disease, the seat of a more confirmed disorder, and of suppuration. In the frontal sinuses inflammation is attended Avith dull heavy head-ach, and pain, in the part. The pain is more severe on stooping; the integuments over the sinuses are swelled, and puffy. The patient is sensible of a peculiar of- fensive smell, and it Avill probably be found, that at intervale, there has been discharge of matter from the nose. All this may be, and still Ave must use general remedies, nor think of performing so formidable an operation, as applying the trepan, on the frontal sinuses. It is much more likely to be a com- mon catarrhal affection, than a formidable disease, or it may prove merely head-ach, assisted by the imagination of the patient. But Avhen there has been injury previously, AAhen there are symptoms of a beginning affection of the brain, when there is occasional sickness, or much languor, or oppres- sion, or any thing like epilepsy, or paralysis, a slighter indi- cation will satisfy the surgeon of the propriety of an opera- tion. If there be a collection of matter, and an inflamed sinus slowly affecting the brain, the delay of an operation may leave us full of regret. If the frontal sinus is to be opened, we must proceed Avith all the precaution?, which we should employ in the more common occasion of using the trephine. 1. We have to recollect the thinness of the outer shell of the bone. 2. The obliquity of the inner table. 3. The partition which divides the tAvo cells. 4. We have to re- member, that the lining membrane of the cells will probably be thickened, and that if diseased it looks like a suppurating brain, and has actually been mistaken for such! 5. That, when the trephine has taken out the circle of the outer table very neatly, the membrane will still be entire, and require to be opened with the lancet. The cure will then be conducted by emollient injections. No tents or dressings ought to be introduced into the cavity. 30 abscess of the maxillary simus. PERFORATING THE MAXILLARY SINUS FROM THE ALVEOLI. The abscess of the maxillary sinus is marked by a colourless swelling of the cheek, over the bone, by a pulsating pain, deep seated in the cheek, generally fixed to the cheek, though some- times extending over the whole side of the head, but not in- creased on pressure, by an oozing of matter by the side of one of the molares, sometimes by a discharge of matter from the nose. We find indeed that the most frequent complaint of our patients is that of foul matter fknving into their mouth, when they lie in bed. We are to be careful to distinguish it from rheumatism tooth-ach and a nervous affection of the face. When it arises from tooth-ach, succeeded by high inflammation, or comes after fever, or succeeding to injury of the bones of the face, or has any such ostensible cause, it is favourable; and by the drawing of one of the molares, or perforating the sinus, and thus allowing a free exit to the matter, the disease will be cured. All the treatment necessary in this disease, is to draw the second molaris, and then to pass up a stilette of the size of a writing quill, into the sinus; nature seems to point out that this is the better place for perforating, though it be sometimes done just above the alveolar process of the molares. The ob- jection to this last place is that without taking away a piece of the gum, it is difficult to keep the perforation open. If the perforation be made in the side of the sinus, then the instrument, which makes the hole for the point of the tre* phine, Avill answer. When a patient presents Avith the sinus opened, and the matter running from it, the operation having been done some time before, Ave are not to despond, but to enlarge the opening for it has probably been made too small. After the operation the swelling may require fomentations, or astringent washes. When the swelling has subsided, and OF THE OPERATION FOR WRY-NECK. 31 the discharge remains foetid, the patient can force the fluid from the mouth into the cell by the tongue merely*. If in this disease there should form an ulcer on the cheek, or just under the orbit, the disease is still to be relieved, by the operation performed beloAv, since that opens into the floor of the antrum while the attempts to preserve the opening on the cheek, and to throw in injections there, will increase the de- formity, even if they should be in the end successful in curing the disease. t WRI-NECK. In the case of wry-neck, which is submitted for operation, the mastoid process, is as it were drawn toAvards the sternum, the head is inclined to that side, and the chin is pitched up. On examining the cause of this, tlie mastoid muscle of that side, will be found to be smaller than that of the other side; it feels stringy and hard; it a\ ill not stretch when the muscle of the other side acts so, that it suddenly checks the turning of the face toAvards the same side. The disease of the muscle which occasions this, is a very singular one. The muscle is changed into a firm substance, Avhich to the knife cuts like gristle, and Avhich is equally inca- pable of contraction, or stretching. I have chiefly seen the portion of the muscle Avhich arises from the sternum, diseased in this manner ; it Avould appear that to others the clavicular portion, lias oftener presented thus changed in its texture. In one instance I traced this disease, to a fall, and twist of the neck. One cannot imagine a more likely cause of this disease, than a strain upon the muscle. I have seen a similar disease, in a portion of the biceps cubiti, producing the effects of an anchylosis, in fixing the elbow-joint. The only thing that the surgeon has to consider deeply is, whether the twist of the head proceeds from this disease or not. Whether the vertebra have not greatly suffered, or it * Tincture oi myrrh, and a little camphorated spirit diluted, is the be*+. v-hen the discharge is foetid. / 32 OF THE OPERATION FOR WRY-NECK. may be, there is almost an anchylosis of the cervical vertebra?. We have to see that there be no paralysis of the muscles; of the opposite side, rather than a permanent induration of this. If the distortion proceeds from a contraction of the skin of the neck, it will be sufficiently apparent, and distin- guishable. OPERATION- The patient may be supported upright on a chair, then examining avcII the tract of the stringy part of the muscle, an incision is made tAvo inches and a half, or three inches in length, through the integuments over this diseased part of the muscle. This will be found to carry the loAver part of the cut, Avithin an inch of the sternum. Having cut down fairly to the surface of the muscle, the muscle is to be relaxed by moving the face to the contrary side, and then the finger, or the handle of a knife or hook, is to be insinuated behind the contracted and diseased part of the muscle. This part is to be cut across by successive lesser cuts, the handle of the knife, or hook which is under it, guarding the parts beloAv ; or a directory is introduced, by aa Inch the knife is guided under the muscle, Avhen the diseased part of the muscle is divided by draAving the knife outAvard; the part as I have said, cuts firm like a tendon or cartilage. When the Avhole diseased part is cut across, the patient feels as if a cord Avhich had long bound down the side of his head was cut across; he can turn the head toAvards the other side. but he brings it round again Avith more difficulty, and for a time the position of the head is aAvkAvard. Noav we will see the advantage of the first incision, being iu the length of the neck, for the more Ave make the patient hold the head toAvards the other side, the closer the lips of the wound are drawn, though the space betwixt the cut surfaces of the muscle be considerable. I have not found the bandage to be necessary, during the cure of young people, the antago- nist muscle answering the purpose ; but if after a long con- OF THE CATARACT. 33 tinuance of the disease, there should be such a change in the form of the vertebrae, that it requires the continued operation of a bandage, then a roller is to be put around the head, and brought over the opposite ear, so as to come doAvn fonvard and pass under the arm-pit. If the distortion be owing not to the rigidity of a particu- lar muscle, but to a more general defect of the muscles of the side of the neck, or to general thickness, and induration of the integuments, Ave must be contented Avith the trial of such remedies as friction, Avith mercury and camphor, and tlie use of the bandage, electricity, &c. If the cicatrix of the skin should be the cause, it is advised that it be cut through, and the head kept in an opposite direction. It is a very troublesome business, and I Avould rather endeavour perseAeringly to relax the contraction of the skin, by giving motion to the head, and here emollient embrocation may also be recommended. OF THE CATARACT. The cataract is the crystalline humour of the eye, be- come opaque. It is characterized in the beginning by these symptoms. The person has a haziness before his eyes, he thinks he sees black specks or flies, or streaks of black moving before him, the vision is indistinct and rather diminished in strong light. Upon inspecting the eye, there is a Avhitencss and turbid opacity in the pupil. This is an affection not pe- culiar to any age, though more common after the middle age. Sometimes it comes suddenly, though oftener very gradually. It may arise from inflammation, in some rare cases it has been dispersed by a casual inflammation. Sometimes there is only a cloudy opacity to be seen in the pupil, oftener the Avhole pupil is of a greyish colour, or it is of a deep milky Avhitencss. When the cataract comes as a consequence of a blow, or of inflammation, it ought to be a reason of delaying the opera- tion, as long as possible, for these oparitie- will sometime spontaneously disappear. vol. ir. ¥ 31 OF THE CATARACT. The following circumstances previous to the operation, have to be attended to. 1. Is the patient though blind, still sensible of the variations of light, does he distinguish a\hen an opaque body is passed before his eyes, or can he distinguish light from darkness ? The reason of attending to this circum- stance is, that Ave may discover if the retina be yet sensible, though the rays of light are Avith difficulty transmitted, through the opaque crystalline humour. 2. Is the iris still moveable? because if it still enjoys its motion, light being its only stimulus, and the retina being alone sensible to light, it indicates the sensibility of the nerve. 3. Further in the mo- tions of the iris, Ave have to observe if the pupil remain per- fectly regular. The irregularity of the pupil, may, most pro- bably, be owing to some adhesion of the cataract, to the edge of the iris, and indicates to us, that there has been a deep in- flammation there. The irregularity of the pupil, is an unfa- vourable circumstance, but not a total bar to the operation. 4. The cataract Avhich has arisen from a bloAV on the eye, or after violent and deep ophthalmia, is, for the same reason, unfavourable. Since it is reasonable to suppose, that the membrane of the lens has been thickened, and has formed a firm adhesion to the surrounding parts. But fortunately the cataract is not often preceded by this inflammation. 5. When we look into the eye, to discover the seat of opaci- ty. We look first nearly perpendicularly into the pupil, but then Ave must turn the patient's head gradually until Ave see the profile of the cornea; and noAV if the opacity should be caused by an effusion in the back part of the cornea, it is dis- tinctly seen to be before the iris. 6. The deep black transparency of the pupil, and the Avarit >f motion in the iris, will sufficiently distinguish the amauro- sis (the insensible state of the retina) from the cataract. 7. The cataract may be of a consistence firmer than the lens is naturally; it may be soft as cheese ■, it may Aoav li- quid like milk, Avhen punctured, but I knoAv not hoAv to fore- see these distinctions by attending to the appearance of the cataract, before operation. OF COUCHING, OR DEPRESSING THE CATARACT. 35 Surgeons of eminence, and oculists, still dispute this point, viz. Avhether the depression or extraction of the cataract, be the preferable operation. The depression of the cataract is done by introducing a needle into the eye, and removing the opaque lens from the axis of the eye. The extraction is a very improper term, but it means the making an incision into the cornea, by which the cataract escapes, being pressed for- Avard by the vitreous humour. In the performance of these operations, the utmost delicacy is required, and they have a result the most interesting of any of the operations of surgery. Although the general opinion, at present, be in favour of the operation of couching or depressing the cataract, yet all > have seen makes me prefer the operation of extraction. I shall, however, describe the operation of couching the cata- ract, first. OF COrCHINC, OR DEPRESSING THE CATARACT. The operation should not be performed on one eye, whih> the other is sound; and when both eyes have cataracts, though Ave have great temptation to operate on both, (by which on the Avhole Ave increase the chance of success) yet I conceive the operation should be done on one side only at a tune. If the eyelids be much affected Avith a chronic inflam- mation, Ave ought to endeavour to correct this, previous to the operation. But if this is obstinate and habitual, and to no great extent, it makes no objection to the operation. No cross light must be admitted into the room; tlie north light is to be preferred, and it should strike obliquely on the eye. 1. TI12 patient is seated on a chair, Avith a long upright back. A pillow is placed to receive his head; the assistant stands behind him to press his head upon the pillow, and in part to support it with his breast. A napkin is thrown over the other eye. 2. The assistant puts the points of his fore and middle fin- ger, on the upper eyelid, and raises the eyelid, at the same time he gives a slight pressure to the eyeball, but rests his fin- 3(i OF COUCHINC, OR DEPRESSING THE CATARACT. gcrs at the same time on the margin of the orbit, so that Avhat pressure they give to the eye may be steady. 3. The surgeon sitting doAvn before the patient, places his foot upon a stool of such a height, that when the elboAv rests on the knee, tlie hand may be opposite the eye. Noav Avith the fingers of one hand, he presses down the loAver eyelid, and when he Avishes to fix the eye, as he is about to introduce his needle, he pushes upon the eyeball Avith the point of his fingers. It is to be particularly observed, that any change of the de- gree of pressure on the eyeball during the operation, is to be made by the motion of the operator's fingers, the assistant has only to keep steady. 4. The surgeon having dipt his needle in oil, he takes it as he Avould a Avriting pen, he rests his little finger on the bone of the cheek, and he pierces the Avhite part of the eye, in the middle betAvixt the margin of the cornea, and the angle for- med by the eyelids, the patient's eye being directed straight fonvards. The needle should pierce the sclerotica in a direc- tion perpendicular to the convexity of the surface, or, in other Avords, pointing to the centre of the eye. 5. The needle is noAv to be someAvhat changed in its direc- tion, and carried horizontally until the point appears behind the pupil, for it is to be observed that, although the opacity of the lens is considerable, yet the needle is seen through it, or Avhen it is immersed in its substance. The flat surface of the point ought to be towards the irk, as the sharp edge might cut the iris. 6. The first motions of the needle, I conceive, ought to be calculated to pierce and tear the anterior part of the capsule of the lens. And this for two reasons. Before the cataract can be displaced from its seat in front of the vitreous humour, its capsule must be broken, and this being done, by piercing it on the fore part, of course facilitates the descent of the cata- ract. Again, Avithout this precaution, it happens that the cataract being couched, the fore part of the capsule remains, and in the inflammation Avhich necessarily folloAvs the opera- tion, it becomes opaque, and forms Avhat is called the mem- OF COUCHING, OR DEPRESSING THE CATARACT. 37 uraneous cataract. We have, therefore, to push the needle in a direction parallel to the iris, and get before the lens, then carry the point through the pupil, so as to burst through, or cut the fore part of the capsule. 7. Supposing that on the first touching the capsule of the len?, a white fluid escapes, and makes the aqueous humour turbid, Ave are not on this account to despair of success; for this milky and dissolved state of the cataract promises a quick absorption, and restoration of vision. It is our busi- ness in this case to tear the anterior half of the capsule, as widely as Ave may, without hurting the iris, and to plunge. the needle repeatedly into the cataract, and then to tie up the patient's eye as usual. 8. Having torn the capsule, the surgeon AvithdraAvs the needle a little, and puts it over the cataract, or pierces the cataract high on its disk. Now the point of the needle is to be depressed, by raising the handle of the instrument; but at the same time that the point of tlie needle is depressed, carrying the cataract Avith it), it must be moved backAAard. A i) For example A, being the lens in its natural situation, to remove it from the axis of the eye, or course of the rays of light B, C, it is not to be pressed directly doAvmv ard in the line D, but in the circular line E, which answers'to the con- cavity of the coats, and by this movement it will be carried down and lodged at F. 9. When by raising the handle of the needle, the operator has carried the opaque cataract thus beloAv the level of the pupil, and the pupil is clear, the operation is not done, for 38 OF COUCHING, OR DEPRESSING THE CATARACT. in all probability, the cataract has not escaped from its cap- sule, and, on Avithdrawing the needle, it will rise again. He therefore would have to blame himself, if, having with- drawn the needle from the eye, he saw the cataract again forced up, and take its place behind the pupil, for the ope- ration would be still to do. When, perhaps after repeated efforts, he has sunk the cataract out of sight, he must cau- tiously withdraw the necC.d from its hold upon the cata- ract, but not altogether upon the eye; then, if the cataract does not appear in the pupil, the needle is to be sloAvly Avith- drawn. The fact is, that when the needle has carried down the cataract, the cataract is not yet unseated from its capsule, and instead of being separated from the vitreous humour that body has revolved Avith; by the elasticity of the mem- brane it will resume its former relation, and of course carry up the cataract, so as again to present it in the axis of the eye. But the cataract may have been separated from its connexions to the fore part of the vitreous humour, and yet rise in a partial manner, on withdraAving the needle ; this is, because it had not been so forced into the vitreous humour, as to break on its capsule, and make a lodgment for itself; the elasticity of the vitreous humour throws it out again. It is incorrect to say, that the cataract has been buoyed up, since it is specifically heavier than the vitreous humour. There is a possibility, that the cataract may escape from under the pressure of the needle, and pass through the pu- pil, into the anterior chamber of the aqueous humour. If the whole or part of the cataract escape thus, we ought to let it remain; it Avill dissolve in the aqueous humour, and be finally absorbed. The cataract may start backAvards, too, so as to be deeply immersed in the vitreous humour. I have seen it faintly shining half an inch behind the pupil. I fancy this is not a frequent accident; if it should happen, Ave are to do no violence in endeavouring to remove it, as Ave are assured it will dissolve, since it must, in this case, be freed of its capsule. OF COUCHING, OR DEPRESSING THE CATARACT. 39 10. It is a more difficult thing to fulfil the intention of the operation, when the cataract is soft or cheesy, for when the needle is pressed upon the cataract, the needle passes through, Avithout dislodging it from its place, nor does the matter Aoav out from the capsule. We ought, in this case, to break, or burst through the capsule, and, as freely as possible, admit the aqueous hu- mour through the anterior part of the capsule; and a second intention ought to be to break down the cataract, which is increasing the chance of its dissolution aftenvards. By perseverance in pressing with the broad edge of the needle, Avithout injury to tlie eye, it av ill often be possible to remove the cheesy matter from the centre of the pupil, so that af- tenvards the patient shall see a little. 11. If there be an adhesion of the cataract to the iris, we shall discover this by the irregular figure Avhich the pupil assumes upon the variations of light, admitted to the eye. During operation, if the depression of the cataract should disorder the regular circle of the pupil, it is OAving to an adhesion, and we must endeavour to separate the cataract, and iris, by the edge of the needle, before Ave attempt final- ly to depress the cataract. 12. If after a feAv days the eyelids are opened, and there appear any fragments of the cataract, they are again to be depressed, or pushed before the pupil by the needle; but, this is not to be done until the inflammation and irritability, the consequence of the first operation, have entirely sub- sided. 13. The remains of opacity behind the pupil, may be Avhat is termed the membraneous cataract. To tear aAvay these shreds, and to push them below the level of the pupil, or through the pupil into the anterior chamber of the aque- ous humour, a needle should be used so curved near the point, that by merely rolling the needle, betwixt the finger and thumb, the point of the needle may be moved pretty exten- sively. With such a needle the operation may be done with less violence, and a smarter motion may be given to the poinl 40 OF COUCHING, OR DEPRESSING THE CATARACT. of it, than where, in order to give motion to the point of tlie needle, Ave have to raise the handle. 14. Any portion of the cataract, or any shreds of the cata- ract, or its capsule, which are accidentally pushed into the anterior chamber of the aqueous humour, are to be allowed to remain there, for they will be dissolved, and carried away by absorption. 15. The secondary cataract is the opacity of the remaining 'capsule, which is not carried doAvn Avith the opaque lens, but remains in its situation. The secondary cataract may be per- fect or partial. It may be said to be perfect when the lens has escaped from the back part of the capsule, and has been immersed in the vitreous humour, Avithout the anterior half of the capsule being torn from its connexions to the ciliary process, or rent in any way. This is more apt to take place, than Ave at first AA-ould imagine likely, from the greater tenuity of that part of the capsule which is toAvards the vitreous hu- mour, than the anterior portion of it. The imperfect, or par- tial secondary cataract, is the remaining shreds of the anterior part of the capsule. It is an opinion, that only the anterior part of the capsule is liable to become opaque, and I think this is very likely ; there is a foundation in anatomy for sup- posing that the anterior, and posterior part of the capsule of the lens, are of a different nature. It is this conviction, that, the fore part of the capsule is most frequently opaque, and that it is the most liable to be so after the operation, that in- duces us to be careful to pierce, and break doAvn this fore part, before couching the opaque lens. If this has been done, only shreds of opaque membrane cas* be visible in the pupil, after the operation. And if t hey ap- pear, Ave ought to let them remain for some time, in the ex- pectation of their wasting, and acquiring transparency again. I have seen, on dissection, an opaque spot on the back of the capsule, and therefore I am forced to say, that the secondarv cataract may be in the posterior segment of the capsule of the lens. But Avhether ths opacity be in the buck, or fore part of the capsule, is of little consequence, since it cannot be distin- OF THE EXTRACTION OF THE CATARACT. 41 -guished in the living eye, (because the vitreous humour forc- es the back part of the capsule into contact Avith the iris, aftei the depression of the lens itself,) and happily it is of little con- sequence to know Avhat part of the capsule is thus diseased, as this supposed distinction would make no variation in the practice. 16. In operating for the membraneous or secondary cata- ract, the intention Avith which we use the needle may be some- Avhat varied. We first endeavour to tear doAvn the opaque membrane, and to place it under the level of the pupil, or we may attempt to gather the shreds of the membrane together, to loosen them from their natural attachment, and to push them through the pupil, into the anterior chamber of the aqueous humour Avhere they will be dissolved and absorbed. We ought not to be too persevering in our attempts to clear the pupil of the membraneous cataract at once, on the contra- ry we should be careful to do little injury, so that we may avoid raising inflammation. We repeat the attempt after a time. The needle should be very fine, and curved at the point, not like that which is adapted for pressing down the cataract of the body of the lens. OF THE EXTRACTION OF THE CATARACT. The extraction of the cataract, I allow to be a more for- midable operation than couching; but when it is Avell done, it is more uniformly successful. I do not know that it is more difficult to perform extraction, than it is to perform couching; but the blunders in this operation are at once apparent, while in couching the errors are concealed; and even the initiated cannot precisely say from the motion of the hand, whether the operator be, with delicacy and niceness of intention, re- moving the opacity from the pupil, or making unmeaning, and consequently, unsuccessful motions of the needle. Freedom from tumefaction and inflammation of the eye- lids, and of all tendency to ulceration in their edges, or to opa- VOI. if. c 12 OF THE EXTRACTION OF THE CATARACT. city in the cornea, is more essentially necessary, previous ta performing the operation of extraction, than of couching. Extraction, let me say, is a bad term, as it indicates that the intention of the operation is to make, an incision, and to pull out the opaque body. This idea is as dangerous, as it is incorrect. The principle on which the operation is done, is simply this. The coats of the eye are tense over the contain- ed humours. Over the coats of the eye, are expanded the tendons of the muscles, while the eyelids have in them the fibres of the orbicularis muscle. The moment that the eye is Avounded therefore, the humour escapes at that part. If an accidental Avound be made on the Avhite of the eye, the vi- treous humour escapes in part. If the cornea be Avounded, the aqueous humour escapes. But although the cornea be punctured, and the water escape, it does not fall flaccid. But the iris and the lens are pushed forward by the tension of the coats on the vitreous humour, and they take the place of the aqueous humour. Should the cornea not be punctured merely, but cut with so wide a wound, as to allow the lens to pass, the pressure on the vitreous humour by the coats and muscles of the eye will be so great, that the lens w ill be thrown in through the pupil, and escape by the wound. The operation to be performed, then, is not to extract the cataract, as Ave speak of extracting the stone from the blad- der ; but only to make such an opening in the cornea, as to alloAv the cataract to be forced out by the tension of the coats of the eye, Avhich is continual; or by the action of the mus- cles of the eye. The necessity of attending to this principle during the operation, I hope Avill be presently evident. INSTRUMENTS. If the operation is successfully done, no other instrument need be used, but a knife, of a form someAvhat peculiar, and adapted to make the proper incision of the cornea. The knife OF THE EXTRACTION OF THE CATARACT. 43 is of the form seen in the succeeding marginal plate p. 45. The point must be very sharp, the back straight, not sharp, and yet not thick; the curved edge very sharp, and the mid- dle of the knife the thickest, and strongest part of it; in the first place, that the knife may have strength to be pushed through the cornea, and in the next place, that it may effect- ually fill up the Avound as it is pushed fonA'ard. The broad- est part of the knife must be fully tAvo thirds of the diameter of the cornea. The incision is made, by passing the point of the knife through the cornea, and across the fore-part of the eye, Avith one uniform motion, and the point entering on one side the cornea, near its attachment to the sclerotica, transfixes the op- posite point, and being still carried forward, the Ioaa'ci* edge of the knife cuts freely through the Avhole loAver segment of the cornea, until it is disengaged. But if the breadth of the knife be not sufficient to make its Avay out, Avhen thus uni- formly pushed onAvard, the edge requires to be pressed doAvn ; an incision larger than the knife can fill up is consequently made, the aqueous humour escapes, and the iris is pushed forward on the edge of the knife! A little oil should be on the point of the knife. To suspend the eyelid, and in some degree to fix the eye; the Avire speculum is best in the hands of the assistant; the ■ pressure to fix the eye must be made by the tips of the sur- geon's fingers, at the same time that he holds doAvn the lower eyelid. A gold needle is among the apparatus of the oculist. The use of this is, to break or cut the capsule, Avhen after cutting the cornea, that membrane strongly resists the effort of the muscles, to protrude the lens. The point should rather be rough than sharp, whether it be made of gold or of any other metal, is of little consequence. Forceps too are necessary, and they must be of such a form and niceness, that Ave may introduce them under the flap of the cornea, and seize any shred of opaque membrane, that may present in the pupil. 'H OF THE EXTRACTION OF THE CATARACT. For the same purpose, and to extract any broken piece of the cataract that is detained, a very delicate hook is to be provided. The cornea scissors are absolutely necessary too, to increase the incision of the cornea, if it shall be necessary, or to sepa- rate any protruding capsule. A fine probe will be found convenient to replace the prolapsed iris, Avhen it shall have fallen out from the incision. Such a probe will also serve to dilate the pupil, if it be necessary; but of this, we will speak presently. OPERATION. The patient is seated on a low chair ; the surgeon is seat- ed opposite to him; the light must be steady, and without glare. A cloth is put over the other eye. The surgeon turns the patient's head until the light falls a little obliquely on the eye to be operated upon; the depth of the pupil, and its nearness to the cataract, is then distinctly seen. 1. Tlie assistant standing behind the patient brings his breast so as to support the back of the head; puts his left hand under the chin, and with the right taking the speculum of Pelier, he raises the upper eyelid by pressing in the in- teguments of the eyelid, betwixt the eyeball and the margin of the orbit. 2. The surgeon, Avith the tips of his fingers, presses the loAver eyelid against the eyeball, so as to fix it; the margin of the eyelid is at the same time carried down so that the cornea stands prominent. The other hand holds the knife. He rests the elbow on the knee,the Uttle finger on the cheek. hone. 3. When the eye is steady, the point of the knife is made to pierce the cornea, Avithin half a line of the sclerotica, and on the outside and a little above the middle of the cornea, the flat side of the knife is toAvards the eye, its straight back upAvards. The knife is noAV carried in a direction toAvards the nose, and at the same time downwards. The nicety of OF THE EXTRACTION OF THE CATARACT. 4j this part of the operation is to carry the knife uniformly for- ward, to press in that degree Avhich Avill keep the eye steady, and yet so to manage the pressure, that the aqueous humour does not escape by the side of the knife. 4. The point of the knife is made to pass over the lower half of the pupil, and enter the opposite side of the cornea, at the same distance from the sclerotic coat, as Avhere the point first entered. Noav, being carried uniformly forward, the loAver edge of the knife will cut the lower segment of the cornea, at the distance of half a line from its connexion Avith. the sclerotica. The knife is here represented, passed, not directly across the eye, but entering near the margiu of the cornea, a little fur- ther up than usual, and the point coming out a little lower. The intention of this is, to prevent the eye from turning towards the nose during the operation ; Avhich it is very apt to do, Avhen the knife is pushed directly from without hiAvard. Although in pushing the knife in this direction, the eyeball should be turned as much doAvnward, as in the other way it would be inward, yet, Avhen the eye is turned doAvmvard, we can better proceed Avith the operation, or more easily turn the eye to the proper direction. When the eyeball moves before the knife, Ave must suspend, as it Avere, the progress of the knife, but not in the slightest degree AvithdraAv it; Ave Avait a little for the ceasing of the spasm, and then Avith the knife, bring back the eye to its original position. Often, I may say, the oculist distracted by » 46 OF THE EXTRACTION OF THE CATARACT. this simple accident, brings out the point of the knife too soon, and instead of making a semi-circular incision of the cornea near its margin, makes a cut, terminating nearly in the middle of the cornea, thus : A. The proper course of the incision, marked by a dotted line. B. The course which the knife has taken in cases, where I have seen the operator embarrassed, by the eye turning in- ward. 5. It is to prevent this motion of the pupil toAvards the nose, that practitioners have exerted all their ingenuity, to form a speculum to fix the eye. The first objection to the use of the speculum, is, that it engages the hand of the sur- geon, when he should have his finger free, to press upon the surface of the cornea ; and secondly, that the speculum ope- rating by pressure on the eye, is apt to force the aqueous hu- mour out, before the incision is completed. 6. Some oculists have recommended, that the capsule of the lens, should be punctured, before the incision of the cor- nea be completed, viz. as the knife is carried through the anterior chamber of the aqueous humour, they depress the point into the pupil, to pierce the capsule. But this is a practice not to be imitated, as the advantage of it, bears no proportion to the danger. The consequence of this manoeu- ATe, too often will be, that the aqueous humour will escape ; then the iris will press fonvard on the edge of the knife, and the incision cannot be completed with the knife. #» OF THE EXTRACTION OF THE CATARACT. 47 f. If by any accident the aqueous humour should escape, and the margin of the iris should fall before the edge of the knife, in this manner, we cannot then carry fonvard the knife. This accident requires calmness. We knoAV how it has happened, and, this knoAvledgc teaches us to remedy it. A little of the aqueous humour has escaped, and the iris is pressed forwards: Ave must restore the equilibrium then, by pressing gently on the cornea. This throAvs back the margin of the iris behind the edge of the knife, and again we can carry the knife straight forward*. 8. But if the aqueous humour, has escaped in such a quantity, that the iris has come in contact Avith the cornea, and lies before the edge of the knife, we cannot finish the section of the cornea Avith the knife. The point of the knife must be AvithdraAvn a little, and brought before the edge of the iris, and made to pierce the cornea loAver down, than Avould be necessary to make an incision of due extent. By this change of the direction of the knife, Ave have made a section of the cornea, Avithout injury to the iris, but it is not of sufficient size to let the cataract pass, Ave must therefore have recourse to the scissors to enlarge it. 9. When Ave have made the section of the cornea too small, and the lens or cataract does not come spontaneous- * Baron AVenzel and Mr. Ware, give the direction to rub the cornea, as if there was a sympathy betwixt the cornea and iris: but as I have not been able to ascertain that any connexion subsists betwixt the rubbing of the one, and the contraction of tlie other, I have given this intelligible reason fei pressing the cornea. 48 OF THE EXTRACTION OF THE CATARACT, ly forward, Ave must insinuate one of the blades of the fiue scissors under the flap of the cornea, and enlarge the incision. 10. I shall suppose that the section of the cornea has been duly made, and the cataract does not immediately follow. Some oculists have recommended that Ave introduce a cu- rette into the pupil, and enlarge it. This is an ignorant a\ ay of dilating the pupil. We ought simply to shut the eyelids, and cover the eye with the hand, so as to relieve the excite- ment of the eye, and by excluding the light the pupil will be dilated, and ten to one but the cataract will be seen coming from under the eyelids, on lifting up the flap of the cornea.— If the cataract be still retained, then it is not the contraction of the pupil Avhich prevents its discharge, but a particular strength in the capsule. And noAv the gold needle, or some such instrument, must be passed under the flap of the cornea, and into the pupil, to break or puncture the capsule, Avhen the cataract Avill be discharged. 11. The Baron Wenzel and other oculists Avho have gained dexterity by practice, without ascertaining the principle, have asserted that " The incision of the cornea is not the most diffi- cult part of tlie operation, and that it afterwards requires much dexterity as Avell as judgment successfully to extract the cataract." AH that I know of the structure of the eye, and Avhat I have seen of these operations, and the difficulties I have myself experienced, contradict this opinion. The suc- cessful incision of the cornea is the operation, and all the un- toward circumstances that may trouble the operator, have their source in the imperfection of the section of the cornea, oi- from some previous disease of the eye, as for example, the thickening of the membranes, or the adhesion of the capsule of the lens to the iris, &c. As soon as the knife has cut itself out, the upper eyelid hould be alloAved to fall; for the uniform support of the eye- lid prevents the cataract from being throAvn out too quickly, or the vitreous humour from folloAving it, if it should escape before the eyelid can be closed. If upon raising the eyelid the lens does not make its appearance, the capsule is to be OF THE EXTRACTION OF THE CATARACT. 49 punctured, and the eyelids again closed to allow the pupil to dilate. If it does not noAv come forward, the small probe is to be introduced under the flap of the cornea, to examine if the incision be large enough; for, from the thickness of the cornea and the oblique direction of the knife, the inci- sion of the cornea may seem to be of sufficient length on the surface of the cornea, when the knife has not penetrated to the inner surface nearly to the same extent: if the incision should prove too small, it must be a little enlarged with the scissors, as I have said. If the cataract does not noAv come out spontaneously Avhen the incision is eAddently sufficient, and Avhen the capsule is punctured, Ave are forced to press the eyeball. 12. We ought not to press the eyeball if it can be avoid- ed ; for there being a difficulty in forcing the cataract through the pupil, when that difficulty is overcome the vi- treous humour is apt to folloAv the cataract; and often it will happen, that the Artreous humour will escape without the lens being discharged. By this pressure the lens is not carried through the pupil, but only the edge of it is pro- truded, and the Adtreous humour escapes under it, while the firmer cataract is retained*. 13. When the iris is cut by the edge of the knife, no pressure must be made on the eyeball, or the vitreous hu- mour Avill escape while the cataract is retained. When the pupil is of its natural form, and the iris entire, the cataract presents behind the pupil, and no part of the vitreous hu- * Thus we find the Baron de Wenzel describing a thing which should never be seen—" The cataract did not give way to the gentle pressure that is usually found sufficient to dislodge it. Its upper edge repeatedly advanced into the pupil, and sometimes almost came through it," &c. Every time the crystalline advanced, a small bladder was per- ceived on Its posterior and inferior edge, strongly adherent to it, and formed by the hyaloid membrane, &c. To press the eyeball in such a state of the lens, and the bladder which is here described, is out of all rule. The bladder is simply the vitreous humour pushing forth un- der the lens or cataract, which has turned its ed being carried bodily through the pupil. VOL. IT. H 50 OF THE EXTRACTION OF THE CATATtACT. mour escapes before it is protruded, but Avhen the iris h cut, the vitreous humour being softer, is carried through the slit of that membrane, and the lens is only turned a lit- tle, but not unfixed, and pressure may force out all the vitre- ous humour before the lens will come. By inattention to this consequence of the iris being cut, I have seen a great part of the vitreous humour lost. If the iris be cut, Ave should then indeed extract the cataract by piercing it Avith the crooked needle; unavoidably, I am afraid, some part of the A'itreous humour will escape. 14. When there is a detention of the cataract by adhe- sion, it is recommended that Ave should carry the golden needle all round the cataract, and in different directions, to separate these adhesions. This appears to me as absurd as dangerous. The adhesion is betwixt the capsule and the ci- liary processes and iris ; Ave have then only to pierce the an- terior part of the capsule, to open it freely, if it be very tough, and then the cataract is discharged, for there is no adhesion betAvixt the capsule and the cataract*. If, after the discharge of the opaque crystalline or cataract, opaque membranes fill the pupil, we may be tempted to extract them ; but if the anterior part of the capsule of the lens bG * "After the cornea and capsule had been properly divided, my fa- ther found that the cataract did not come through the wound on his making the usual pressure. He was therefore obliged to introduce the needle and carry it in different directions round the crystalline, in or- der to destroy tlie adhesions it had formed to Uie posterior parts of the iris. This part of tlie operation took up at least fifteen minutes." This is the recommendation of the Baron de Wenzel, his son, and the commentator, Mr. Ware. On this account we first ask ourselves, why was the capsule punctur- ed, but that it might burst freely open, and allow the cataract to escape; and if the cataract did not escape, was it not owing cither to a bad in- cision, or if that is not likely in so dexterous hands, to the strength and toughness of the capsule ; why therefore was the intention of the operation changed; why, because the lens would not come forth, and drag the capsule with it ? To have cut the capsule freely open, and to have dilated tlie pupil, was what should have occurred to us as proper to be done. OF THE EXTRACTION OF THE CATARACT. 51 ruptured, though the shreds of that membrane may be visi- ble, (oAving to their opacity), yet I conceive we have nothing farther to do, but to close the eye. By holding the patient's eye thus exposed to the light, and introducing instruments under the cornea, we excite spasm in the muscles, and a^ the membranes Ave arc tearing aAvay, are connected Avith the vitreous humour, it is scarcely possible in this attempt to avoid losing much of that humour. If the anterior part of the capsule be opaque, the lens hav- ing burst through it, it will, I imagine, be belter to let it take the chance of Avasting in the aqueous humour, than by tearing it aAvay to endanger the entire loss of the organ, in consequence of the discharge of the vitreous humour. 15. When the cataract is discharged entire, Ave ought to have little further anxiety, I imagine, that to see that the iris does not hang relaxed into the incision of the cornea; as light contracts the pupil, so will opening the eyelids make the relaxed iris draw up; but if it be at all engaged be- tAvixt the edges of the cornea, it Avill. require to be replaced by insinuating the small probe into the incision. 16. When the operation is finished, Ave must see that the edges of the incision come accurately together, then the eye- lids should be closed, and some plies of wet lint, hung be- fore the eye; the clothes must not press much upon the eyelids. Before putting the patient to bed, Ave must see that the margins of the eyelids are properly together, and that none of the eyelashes are turned in upon the eye. The eyelids should be looked to the next morning, and if neces- sary, bathed and cleaned of any secretion; the eye should be examined carefully on the third day, but the eyelids in- stantly replaced, and the patient enjoined repose and dark- ness for ten days. 17. It is, in my opinion, entirely out of the question, to perform the operation of extracting the cataract a second time. If there occurs any necessity for removing a remain- ing opacity of the pupil, after the crystalline humour h;r J2 OF THE TREATMENT OF THE EYE been discharged, and the incision of the cornea healed, it must be done by the needle, as practised in couching. OF INFLAMMATION OF THE EYE, AND OF THE TREATMENT AF- TER OPERATION. The eye is necessarily the most delicate structure, and exposed more than any similar part of our frame. The na- tural delicacy and transparency of its membranes are preserv- ed in a manner truly admirable. The tears which wash its surface, we must have observed, are acrid and stimulating, and when they run over the cheek, inflame and excoriate the surface. But the delicate surface of the eye and eyelids are accommodated to the presence of this fluid, and the advan- tage resulting from this is, that the surface is not disordered or irritated by any lesser degree of stimulus, and consequent- ly it bears the variations of the atmosphere, and the excite- ments it is necessarily exposed to. Yet Avhen Ave consider the exposure of the surface of the eye, and the delicacy and vascularity of its membranes, we cannot wonder that it should be often inflamed, and often suffer from those derangements of the constitution which art not to be remarked but by some such local affection as chronic inflammation of the eye. I see chiefly these distinctions in the inflammation of the eye : 1. An acute inflammation, Avith evident symptoms of constitutional derangement, marked by nausea and a fur- red tongue, or accompanied with inflammation of the mu- cous membrane of the nose, and sinuses, and symptoms of in- flammatory fever; or an inflammation similar in .symptoms, but most commonly resulting from outAvard impression. 2. A lower degree of inflammation, chronic, and resisting lo- cal remedies, Avhich is resulting from some derangement of the system. 3. Lastly, an inflammation only resembling the others in appearance, the effect of local debility in the eye, and characterized by a relaxed state of the vessels, and a AFTER OPERATION. 53 fulness of the membranes, the consequence of a preceding vi- olent inflammation. 1. In the first example, while the inflammatory action is to be subdued, all that will excite, is to be removed in the first stage; every surgeon of good practice forewarns us to notice Avell that change which takes place, Avhen instead of the violent throbbing, the acute pain, and hot Avatery dis- charge, there is only a SAvelling and turgessence in the mem- branes, Avith a diminished irritability, the eyelids more flac- cid, the fieriness being gone though the redness remain, and the pupil be more dilated ; noAv the evacuations, the sooth- ing and emollient applications, Avhich Avere necessary at first, will only continue the symptoms, and tend to fix the com- plaint, Avhile cold stimulating and astringent applications, are to be employed. The mere consequences of violent ophthalmia, and Avhicli are not to be considered as fixed or peculiar diseases, are the phlyctenaz, Avhich are small vescicles formed on the surface of the eye; the chemosis, which is the swelling and projection of the conjunctiva; the puriform discharge from the eyelids, (which when in a remarkable degree, I am inclined to believe is always owing to matter communicated to the eye); the hypopion, Avhich is a deposition of coagulable lymph in the anterior chamber of the aqueous humour ; the bursting and total destruction of the eye ; all these, as sure consequences of the high inflammation, are to be prevented or cured by re- moving the inflammation. But the several diseases I have noAv to mention, as requiring operation, we may better consi- der as the consequences of the continued chronic ophthalmia, and Avhich from the sloAvness of their formation do gradually acquire a kind of constitutional permanency Avhich requires excision. I may say once for all, what I conceive to be necessary in the examination of these diseases, in order to discover if any thing should be done previous to operation, and what treatment is to be pursued after the operations upon the eye, Avhen inflam- mation is a consequence 54 OF THE TREATMENT OF THE EYE, &.C. When any neAv membrane seems to be formed on the eye, any pustule, ulcer, or opacity, accompanied with clusters of turgid veins, or a general relaxation and fulness of the vessels, before taking the knife to these, Ave ought to examine if any accidental cause has existed Avhich is now happily removed ; or whether or not by the foulness of the tongue, the want of appetite, the languor and sickness, the occasional rheumatism in the face and head, or head-ach, or any such slight affec- tions, there exists derangement, in the system, or- debility and consequent accumulation in the stomach and boAvels. We must examine Avell Avhcther the local disease partakes of the character of scrophula or syphilis.—The influence of these causes ought, if possible, to be removed before operating on the eye. Previous to an operation the patient should take a smart purge; from the immediate debility proceeding from this he ought, hoAvever, to be recovered. The immediate effect of a severe or protracted operation on the eye will often be a nerv- ousness and sickness, or coldness, shivering, and head-ach; this state an opiate with an aromatic will remove, and as it will often happen, that the irritability of the stomach will prevent the medicine from being retained, if the opiate be given in the form of clyster to the quantity of what Avould be a double dose if taken by the mouth, it will cause the commo- tion and sympathy of the frame Avith this most irritable organ to subside. If blood flows from the eye in consequence of the operation, it is to be promoted by bathing the eye with tepid Avater. After all operations on the eye the patient must be condemn- ed to darkness, and Ioav diet; a Avet rag be put on the eye, the bowels must be kept open. He must not indulge in bed, nor lie Avith his head low, nor have his head and eye loaded with bandages and dressing. Opiates should be held in re- serve as long as may be. That inflammation which proceeds from the stimulus of the knife, should be treated with emol- lients, and the eyelids washed with tepid water. The astrin- gent collyria should be reserved for that stage when there re- RELAXATION OF THE EYELID. 55 mams not the smart action of vessels, and the acute sensibility, but, on the contrary, a relaxed state of the parts only. There is a niceness of observation necessary, to be able to say Avhen the operation has ceased to produce its effect, Avhen it may be repeated or when a caustic may be applied to assist in the cure, supposing an excrescence or tumour has been cut off. Even after this effect of the mere irritation of the knife might be expected to have subsided, there will often come on symp- toms of general disorder, head-ach, and increase of heat, with restlessness and watching. But the tongue, the bitter taste of the mouth, and nausea, point out to us the necessity of gently moving the bowels; these symptoms wiU yield to quietness, low diet, and occasional clysters. This loAATiess of diet, we must remember, is not to be the universal order, but observing Avhen there is a tendency to high action, or irritability of Aveakness present, Ave must half starve some, and give more generous diet to others. Above all Ave must guard against the complaint being fostered and supported by confinement and bad air, Ioav diet and despond- ence, for this reduces the system to that state Avhich, though not actually disease, is particularly unfavourable to the cure of surgical diseases. RELAXATION OF THE EYELID. There may be a difficulty of raising the eyelid, from an irregular motion and spasm of the orbicularis palpebrarum*. There may be a difficulty of raising the eyelid, from a loss of poAver in the levator palpebrze superioris. There may be a relaxation of the upper eyelid, in consequence of inflammation long since subsided ; a fulness of the cellular membrane, which prevents the action of the levator muscle. In this last case a portion of it may be cut off, so as to relieve the eyelid, Avhich otherwise hangs over the cornea, and obscures vision. * An irregular nervous affection producing it, as in hysteria. 56 OF THE INVERTED EYELID. EVERSION OF THE EYELIDS. (Ectropion). The conjunctiva having been inflamed, there sometimes re- mains a tumefaction in the conjunctiva, with a weak chronic inflammation. The edge of the eyelid is turned outAvard, and there is a semilunar, pale, fleshy tumour betwixt it and the eyeball. The cornea sometimes appears sunk within a circular tumour. The eyelids no longer wipe the dust from the cornea ; they are removed from it; the eye is hot, and the tears fall over the cheek, there being no longer the gut- ters left betAveen the meeting of the ciliary cartilages, to con- vey the tears to the puncta*, and there occur of course fre- quent attacks of more violent inflammation, and in the end aa opacity or ulceration of the cornea takes place. ' In slight cases the tumours are only to be scarified, or the surface, (if it shall have granulated) may be destroyed with the lunar caustic. The object in both these Avays is to produce a cica- trization and consequent contraction of the conjunctiva. When the disease is more confirmed and the semilunar tu- mour of the conjunctiva considerable, the Avhole protruding part is to be cut off. To do this, it is seized Avith the hook or forceps, and Avith the crooked scissors it is to be cut off. After this a few touches of the knife may still be necessary, and during the cure the end may be further secured, by touching any prominent granulation Avith the caustic and by the use of astringent Avashes. OF THE INVERTED EYELID. Inversion of the eye is Avhere the margin of the eyelids and consequently the eyelashes are turned inwards upon the eye, proving a continued source of irritation and inflammation. * There is a lesser degree of this disease, common to old people, which is not meant to be spoken of here. OF THE INVERTED EYELID. 5/ No spasm or violent action of the muscles of the eyelids will produce this inversion, nor will the paralysis of the same mus- cles have any tendency to form it. It is one of the many consequences of chronic inflammation, which making, as it were^ a permanent groAvth of the superficial part of the eye- lid, while the conjunctiva remains contracted it folloAvs of course, that the edge of the eyelid is turned in. It is then in all respects the exact reverse of the eversion, and tumour of the conjunctiva. But perhaps this position of the tarsus is not merely the consequence of a fulness of the cellular membrane, or groAvth of the skin, but in consequence of ulcers; the in- ner surface of the eyelid and tarsus may be contracted by the forming of the cicatrix. The surgeon then has to determine by careful examination, whether or not the inversion be owing to the growth or re- laxation of the outward skin and cellular membrane of the eyelid, and if it be, there is this method recommended of re- moving the evil. With the finger and thumb a portion of the skin of the eyelid is raised, so as to hold a ply or double of the skin, parallel to the margin of the eyelid. In doing this the sur- geon will be able to distinguish betwixt the skin and the mus- cle, and Avill of course be careful to avoid catching hold of the orbicularis muscle. The scissors are now applied so that an oval piece of skin, or rather a piece of the form of a myr- tle leaf is cut out. The appearance of the eye is frightful, but first by means of an adhesive plaister, and then by a com- press and bandage the skin of the eyebroAv is brought doAvn so as to allow the margins of the Avound to approach. The cicatrix forming consolidates and gives firmness to the out- ward skin, so as to keep the cilice from being longer inverted upon the eye. But if this inversion of the eyelid be a consequence of ul- cers and contraction of the inner and cartilagenous edge of the eyelid, forming a kind of stricture Avhich prevents the inner edge from rising fully over the eyeball, and which drags in and inverts the margin of the eyelid, then a different ope- vol. n. i 58 •F TIMOVRS OF IHE EYELIDS. ration is performed. Having forcibly turned out the inside of the diseased eyelid, the inner membrane of the eyelid, and the ciliary cartilage are to be cut across by the point of a lancet. If the inversion of the eyelid has arisen from the al- leged cause, it will be immediately relieved. OF TUMOURS OF THE EYELIDS. There are tumours of the eyelids Avhich the patient is very willing to have taken off, and Avhich should be taken off because they push in the tunica conjunctiva, and pressing upon the eyeball, in the motions of the eyelid, they inflame it. These are small incysted tumours growing in the place of the meibomean glands, and it is natural to suppose that they are the enlarged glands. But we must observe, that there are,tumours of the eye- lids Avhich ought not to be cut. These are small tumours Avith a broad base, and of a dark red colour. Sometimes they have the appearance of a small boil, being white on the most prominent part: yet this is not pus#. On the contrary, the tumour Ave have to cut out is colourless, only in as much as sometimes by exciting the eye there may be some general inflammation. These incysted tumours of the eyelids, it is needless to at- tempt to remove either by local remedies, or by attention to general remedies, they must be cut out, or the patient must submit to the inconvenience; I must add, hoAvever, that there is more pain and bleeding than Avould be imagin- ed to be the consequence of so trifling an operation. The first thing to be examined is, Avhether or not the tu- mour be so united to the inner membrane of the eyelid as to force us to cut through the eyelid altogether, before Ave * Hordeolum. In this tumour of the eyelid we should do very little, un- less it be to move the bowels. When, however, the little swelling advances, this white speck bursts and discharges a little fluid, and then a slough is seen within, which is by and bye pushed out, and the sore closes, to promote Which, fomentation and poultices are used. OF TUMOURS OF THE EYELIDS. SO can take aAA'ay the tumour, if AA-e should operate by making our first incision on the outAvard skin. If the conjunctiva seems intimately united to the tumour upon our everting the eyelid, Ave have to proceed thus ; As in all operations on the eye, the patient is firmly seat- ed, and an assistant standing behind him supports the head against his breast 1. The assistant must invert the eyelid, by catching the eyelashes and margin of the eyelid with his fin- ger and thumb, and turning his fingers, so that the fore-fin- ger pushes forth the tumour and everts the eyelid. 2. The surgeon noAv draws his lancet pointed scalpel across the tu- mour, so as to diAdde the tunica conjunctiva in a direction parallel to the edge of the eyelid. 3. Having by scratching a little separated the membrane, so that the tumour is thrust out, he has to push a hook or small tenaculum into it, and then to dissect it away altogether. But if the conjunctiva be not diseased or very firmly unit- ed to the tumour, Ave had better operate without everting the eyelid, and this is possible without leaving an observa- ble scar on the eyelid. 1. The surgeon fixes the eyelid by pressing the tAvo angles doAvn by the points of the fore and middle fingers, and having stretched the outer skin of the eyelid over the tumour, he draws his knife directly over the tumour and parallel to the edge of the eyelids, consequently separating the fibres of the orbicularis, not cutting them across. 2. Having exposed the outAvard half of the tumour he pushes the fine tenaculum round under it, and then dissecting it a little more, he applies the curved scissors, and cuts it off from the tunica conjunctiva. The orbicularis muscle holds the lips of Uie Avound to- gether, Avithout our assistance, and then it is only required that Ave bind lightly on the eye a cloth wet with cold solu- tion. When tumours grow Avithin the socket, they are to be early extirpated, for though they should be of a harmless nature, yet their increase, simply by pushing the eyeball fonvard, and 60 ENCANTHIS. stretching the optic nerve, will cause blindness and deformity, while by filling the socket and pressing more and more on the eye, the operation of cutting them out becomes daily more difficult. ENCANTHIS. The EncaHthis is a tumour arising from or at least involv- ing the caruncula lacrymalis, it is of a pale red colour, and irregular on its surface ; as it increases it draAvs into its sub- stance the semilunar fold of the conjunctiva and stretches its root along both eyelids. When this tumour is of a darker hue and hard, and has lancing pains in it, and still more when becoming more active and vascular, it bleeds easily or ulcerates, it is becoming cancerous. Even before the tumour shews this cancerous character there occur good reasons for cutting it off. When it becomes rooted in the eyelids, and the cancerous disposition has spread, nothing but the extirpation of the Avhole eye will avail, if even that is effectual. When the tumour is not of a malig- nant nature, and when it has only produced the lesser evil of a Aveeping eye, by its pressing the puncta, and caused inflam- mation of the eye, by preventing the eyelids from meeting, it may be cut out Avith more hopes of success. We may do it thus: 1. The assistant turns doAvn the lower eyelid with his finger, or with the assistance of a flat and blunt hook; the sur- geon then Avith a pair of nice forceps, and very sharp knife, dis- sects off the root Avhich the tumour has shot along the inside of the eyelid. 2. The assistant then turns up the superior eyelid, when the surgeon in the same Avay dissects off the root of the tumour from this eyelid. 3. Now the body of the tu- mour is to be pierced with the hook and drawn outward, and if it should appear that the caruncula lacrymalis is natural and distinct from the tumour, then the latter is to be dissected off from the caruncula lacrymalis; but if they shall be incorpo- OF THE PTERYGION. Ol rated, the whole is to be taken aAvay. 4. The last part of the operation is to dissect up the diseased conjunctiva from the surface of the eye-ball. After the operation, the eye may be fomented until a con- siderable quantity of blood be lost, and aftenvards emollient fomentations will only be required, if no cancerous affection has prevailed. OF THE PTERYGION. «• The Pterygion is a pale red film, Avhich stretches generally from the inner angle of the eyelids, across the cornea. It is one of the pure consequences of continued inflammation. When this web covers the Avhole eye it is called pannus. But the terms film and Aveb deceive us, for this is not a neAv mem- brane formed on the surface of the eye, but only a congestion in the cellular membrane, under the conjunctiva, Avhich, as it were, loosens it from the sclerotica, at the same time that its vessels are increased in number, and become tortuous. This diseased state of the conjunctiva encroaches in a conical form on the lucid cornea : it- is there too of the same nature; the transparent outer lamina of the cornea becoming opaque, and feeing at the same time loosened in its texture. OPERATION. 1. The patient being seated Avith a cloth under his chin, (he assistant stands behind him and supports his head, having in one hand a sponge full of tepid water, Avhich from time to time, in the progress of the operation, he pours into the eye, as it becomes obscured by blood. The assistant opens Avide the eyelids. 2. The surgeon noAv Avith very fine forceps raises the apex of the pterygion which is on the cornea; he then pushes the knife, used for the extraction of the cataract, under the fold of the membrane which he has raised; he carries the knife for- ward until the edge shall have cut itself out, and have sepa- rated the very apex of the membrane from the cornea. 62 OF OPACITY OF THE CORNLa. 3. Now holding the membrane up it is to be dissected a little from the Avhite part of the eye, and lastly the scissors are to be applied (pointing upAvard or downward), so as to cut across the middle of the membrane, where it is attached to the albuginea. The eye is to be noAv washed Avith tepid water, while the blood flows, and then a light compress of wet linen is to be put on the eye. The surface which has been diseased ac- quires a peculiar yellow colour ; it is some weeks in contract- ing fully, and forming a cicatrix. The treatment after this is only such as Avould be prescribed to suppress any appear- ance of returning inflammation. That part of the cornea from Avhich the pterygion has been cut off, does never entirely recover its transparency. OPACITY OF THE CORNEA. 1. The cornea becomes opaque in several Avays. Inflam- mation may leave in it a milky opaque spot or spots, from an effusion under the outward lamina. There is at the same time a flaccid state of the conjunctiva and tortuous or varicose veins lead to the opaque spot of the cornea. This has been called nebula, from its producing only a cloudiness in the vision. 2. If the cornea be opaque in consequence of a preceding very violent attack of ophthalmia, the effused matter will be found to be deposited deeper in its substance, and is supposed to be coagulabie lymph ; this is the albugo. 3. Again, there occurs in consequence of inflammation, a postular opacity, Avhich, breaking, forms an ulcer, which leaves a firm opaque cicatrix, viz. leucoma. The practice in the first instance of opacity (the nebula) is to extirpate the tortuous fasciculus of vessels, whose elonga- tion over the cornea caused, or necessarily accompanied the formation of this opacity, and Avhich we may noAv suppose, feed and support it as it Avere. Tlie fine eye-scissors and a common houseAvife needle, stuck witk its head in a piece of ©F OPACITY of the cornea. 63 wood, are sufficient apparatus for this end. The head of the patient is supported against the breast of an assistant, and the eyelids held asunder Avhile the eyeball is at tlie same time pressed so as to steady it. 2. The surgeon passes the needle under the fasciculus of vessels, so as to lift them from the sclerotica near the margin of the cornea. He then places the scissors so under the needle as to cut out a considerable portion of the conjunctiva and the congeries of vessels. Tlie eye is to be fomented so as to continue the bleeding from the cut vessels. The opacity of the cornea will often disappear the first or second day after the operation. When a young man asks hoAv is this supposed deposition in the cornea absorbed, I cannot give him a satisfactory ansAver. The practice in the more permanent opacities of the cornea, viz. the albugo and leucoma is very vague, because of the great difficulty of removing them, and the frequent disap- pointment in tlie attempt to cure them. All that is to be said, seems to resolve into this—if there be a remaining in- flammation or laxity of the vessels of the eye, this is to be re* moved by local and general means;—if, on the contrary, all inflammation has subsided, and the speck is stationary, we endeavour to excite such an action in the part by stimulants, as may produce eventually some change in the disposition of the part. APPLICATION OF CAUSTIC TO THE CORNEA. Ulcer in the cornea may be a consequence of violent in- flammation, or a direct effect of external injury. It has been roundly asserted that the ulcer of the cornea is oftener the cause of the ophthalmia, Avhich accompanies it, than the ulcer is a consequence of the ophthalmia. This teaches us not to trust to general remedies for the removal of the inflammation. The ulcer then is to be touched with the lunar caustic. This of course deadens the very sensible surface of the ulcer, and it being no longer sensible to the acrid stimulus of the tears, the irritation subside*. w OF THE STAPHYLOMA. The best way of applying tlie caustic is to have it set in a quill, and put on the stick of a pretty large camel-hair brush; the caustic must be cut down to a small point; a little milk is beside the surgeon, in Avhich he dips the brush. He then raises the eyelids, and at the same time presses them to fix the eyeball, he touohes the ulcer with the caustic, and presses it to the bottom of the ulcer, and when he has done this he brushes the liquified caustic from the eye Avith a motion of his brush.—In a day or tAvo the irritability of the eye returns, for the deadened surface of the ulcer has separated, and the tears again come in contact with the sensible surface, but the pain and intolerance of light is less than before ; it is to be touched again Avith caustic, Avith a more permanent relief of symptoms. And if things go on successfully on the clearing of the ulcer in successive times, instead of being eaten deep it is shalloAver, and fills up, and the inflammation subsides. The caustic need not be applied after the irritability ceases, and the ulcer looks red and granulating, instead of being irre- gular and cineritious in colour. of the staphyloma. The Staphyloma is an opaque conical tumour of the cor- nea, it is often of a white or pearl colour, sometimes dark or variegated by the accretion of the iris to it. The staphyloma is most generally a consequence of small-pox. The opacity of the cornea produces blindness of that eye, but the worst circumstance of the disease is, that although it has no malignity, it is always liable to be aggravated, and to affect the other eye also. The tumour of the cornea project- ing from betAvixt the eyelids, remains dry, and becomes ulcer- ated ; there is a continued inflammation of the eye produced, and from the intimate sympathy which exists betAvixt the eyes, the other becomes sore also, and even ulcers form on the cornea of it. When Ave knoAv this to be a consequence of the staphyloma, avc cannot hesitate about cutting it off. OF THE STAPHYLOMA. 65 The intention of the operation is to evacuate the humours of the eye, that the coats may contract, and be Avithin the margin of the evelids- operation. The patient is seated as for the extraction of the cataract* and the assistant supports the eyelid in the same manner. The surgeon takes the largest of his knives for the extraction of the cataract, and pushes it through the tumour, in the direction he Avould cut the cornea in the operation of extrac- tion ; but he does not enter the knife so near the margin of the cornea as in that operation. Having made a section of the loAver half of the tumour, he takes hold of the flap Avith the forceps or sharp hook, and completes the circular incision. The tumour being cut off, and the chamber of the aqueous humour largely opened, the humours of the eye are gently squeezed out of the coats, when the eye subsides Avithin the eyelids. The cornea being the only part cut in this operation, and this being a part neither vascular nor very sensible, the in- flammation is some time of commencing. On the fourth day the eyelids are inflamed, and on the seventh or eighth there is pus on the poultices applied to the eye. Scarpa in particular recommends the operation to be performed as I have here de- scribed, saying, that very terrible consequences result from including the sclerotic coat in the incision. But I have seen the operation performed by cuttiug off the whole anterior segment of the eye Avithout any bad consequence; notAvith- standing this, the reasoning as well as the facts alleged by Professor Scarpa, must sway us, Avhere there is no advantage resulting from a practice opposed to his. After the operation a pledget of soft lint soaked in oil, may be applied over the eyelids, and Avhen the inflammation rises, if the fever and pain be great, Ave must bleed largely, and, as we wish to produce suppuration on the surface of the mem VOT. Tf. k 66 OF THE PROTRUSION OF THE IRIS. brancs, avc must foment and apply poultices, not repellent cold applications. PROTRUSION OF THE IRIS. The protrusion of the iris is marked by these characters. There is a small prominent tumour or speck on the cornea of the colour of the iris. Around its base the cornea is opaque. The pupil is a little removed from the centre, and somewhat changed from its regular form, and the plane of the iris is more oblique than natural; the vessels of the conjunctiva are large and numerous, and the eye is particularly irritable. This is a kind of hernia of the iris, which is apt to occur after the operation of extracting the cataract, or in conse- quence of Avounds or ulcers of the cornea penetrating to the chamber of the aqueous humour. This is not a relaxation and falling doAvn of the iris, but it is pushed out as an intes- tine is in hernia, by the contraction of the eyeball, and in the narroAv opening of the cornea it is sometimes strangulat- ed too like a hernia. It is impossible to reduce this pro- trusion Avhen it is the consequence of ulcers of the cornea; for supposing that the iris Avas separated from the cornea, would not the aqueous humour again be discharged, Avould not the lens again press fonvard the iris, so that it Avould be pushed through the opening of the cornea ? The entangling of the iris in the ulcer is not owing to this membrane float- ing Avith the current of the aqueous humour, toAvards the opening; but, as I have described in speaking of the extrac tion of the cataract, the Avhole contents of the eye press for- Avard to the breach, and the iris presents first. It has been well observed that this presenting of the iris in the ulcer, saves tlie eye from total destruction, though it be a painful disease in itself. The practice in this disease is simple. We have to touch it with the lunar caustic ; this must be done with the precautions already recommended; the small black tumour formed by the protruded iris must be eat down Avithin the level of the cornea by repeated application of the DROPSY OF THE EYE. fit- caustic. After this Ave are to endeavour to promote the cicatrixation of the ulcer. In the same AAray are treated the small lymphatic tumours, which project from the cornea, after an ulcer or Avound. Scarpa proves that this tumour is tlie protrusion of the vitre- ous humour and its capsule. DROPSY OF THE EYE. Like every other part of the body the vessels of the eye receive a constitutional disposition that keeps the form and proportions of the humours and coats to a limited form. If this natural action of vessels be changed, the effect is some defect of transparency, or some preternatural groAvth; there is an atrophy or Avasting of the eye, or a great increase of the humours, a distension and groAvth of the coats—a dropsy of the eye. Dropsy is sometimes a consequence of injury done to the eye, or of high inflammation; sometimes it attacks slowly and Avithout any very evident cause. The symptoms are, a sense of distension with pain in the orbit and difficulty of moving the eyeball. Blindness ensues, and there is no longer contraction of the pupil. In a still greater degree of the disease, the eye projects conically from the eyelids, and they no longer shut upon the eyeball; the exposed surface be- comes acrid ; there is inflammation and ulceration of the eye- lids ; the eyeball is inflamed, Avith great pain and head-ache ♦, the other eye i- affected, by sympathy ; and an operation be- comes absolutely necessary. The Operation is sufficiently simple. The eyelids arc held open; a sharp tenaculum is thrust through the anterior half of the eyeball, and all the projecting part is cut off Avith tAA'o motions of the scalpel. The humours arc of course spon- taneously evacuated, and the eye shrinks Avithin the eyelids. But Scarpa again frightens us, and recommends instead of this, that the middle of the cornea be cut, as in the Stn- phyloma. OS Of THE A1UIIICIAL PLfll OF THE ARTIFICIAL PUTIL. In deep inflammation of the eye, following the operation of extraction or depression of the cataract, the pupil contracts and closes altogether; for during the inflaniniation there being also great irritability of the eye, attended Avith contraction of the pupil, the iris fixes and adheres, so that there is an entire obstruction to the light. The contraction of the pupil is some- times more unaccountable, being gradual, and only accompa- nied Avith a slight degree of unusual irritability in the eye. The contraction of the pupil is, hoAvever, a rare complaint. One should naturally suppose that it Avould be an easy opera- tion to introduce the couching needle, and cut the iris in the middle part, so as to enlarge the contracted pupil, or form a neAv one. But it is found, that Avhen the pupil is made in the centre of the iris it quickly closes again. So it happens Avhea the circle of the iris is divided from the circumference through its edge, Scarpa has substituted another operation, of which I should say little, not having performed it on the human eye, Avere I not certain of its practicability by trial on brutes, and did I'not conceive that it is a means of restoring sight in a case not yet thought of.—Scarpa performs the operation in this Avay:— The patient is seated as for the operation on tiie cataract. The surgeon uses a very small, straight couching needle. He perforates the scleroLic coat, as for the depression of the cata- ract, and about Iavo lines from the margin of the cornea; tin point of the needle is carried behind the iris, and before the lens, if it has not been extracted. It is made to advance as far as the upper and internal part of the outer margin of the iris, viz. on the side next the nose. The point of the needle is then made to pierce the root of the iris, Avhere it is attached to the ciliary ligament, and Avhen the surgeon sees the point of the needle projecting through the outer margin of the iris, he draAvs the instrument towards him, so as to separate the iris from the sclerotic coat. Blood is effused dming the oper^ OF THE ARTIFICIAL PUPIL. 69 lion, so that the aqueous humour becomes turbid, the pain is greater than in the depression of the cataract, and for these reasons the motion of the needle should lie decided and quick. Some time ago, before I had occasion to consider this sub- ject of the contraction of the natural pupil, a patient applied to me Avho had an opacity of the cornea, covering the natural pupil. As the gentleman possessed the sight of the other eye, I did not advise an operation, Avhich yet I thought practica- ble, if he had been blind altogether. I thought of opening the iris opposite to the transparent part of the cornea. FIG. 1. FIG. 2. These sketches of the eye aa ill illustrate Avhat I conceived il possible to do. In figure 1. the opaque cornea at A, covers the pupil, the relative place of Avhich is marked by a circular line of dots.

With this eye the gentleman cannot see but very obliquely, and imperfectly, although the pupil is quit* clear of cataract. In such a case as this, supposing that vision was not per- fect in the other eye, the sight might be restored, by making an artificinl pu- pil in th^ iriq opposite to the tran-Mwren* part of the cornea. ro LX1IRPATION OF THE EVE. It was Avith great satisfaction I read Scarpa, on the sut> ject of the artificial pupil. The cause for Avhich he performs that operation is rare, but if it shall prove effectual for those opacities which are opposite the natural pupil, Iioav much more extensive must the benefit prove. EXTIRPATION OF THE EYE. The patient is placed on a chair, Avith his head resting on the assistant's breast. The assistant should hold in his hand a blunt hook with which he is to raise the eyelid. The sur- geon is seated before the patient. He now pierces the anteri- or segment of the eye with his tenaculum. The first strokes of the knife are tAvo semicircular incisions, to cut through the tunica conjunctiva, and to separate the eyelid from the eyeball. Then if the eye is very much distended and fills the socket, the next motion of the surgeon's knife ought to be to punc- ture the eyeball, and alloAv some of the humours to escape ; for, if this is not done, he is cutting in a constrained and nar- row way, betwixt the distended eye and the socket, making a tedious operation, and endangering more than necessary, the bones of the socket. When tlie conjunctiva is cut, and the knife has gone quite round the eye and tlie attachments of the tAvo oblique muscles are cut through, the eye would lie loose, only that the optic nerve retains it very strongly. I have seen the surgeon unac- countably forget this, and make repeated and most painful ef- forts, by cutting and pulling, when it only was required that he should have cut across the optic nerve. To cut across the optic nerve, the knife ought to be carried flat under the superciliary ridge, and made to glide along the orbital plate. When passed over the eyeball in this direction, a single cut will sever the nerve and muscles Avhich surround it, so as to relieve the diseased parts, and they may be draAvn out Avith only a little adhering cellular membrane. A good deal of blood should be allowed to Aoav. If it be required to stop the too profuse bleeding, it may be done by pressing a little dry lint in the inner angle. EXTIRPATION OF THE EYE. • * INSTRUMENTS. A strong flat tenaculum may do to pierce the ball of the eye Avith; or a large ligature is put through the eye Avith the common surgeon's needle, or Avhat -will be found more useful, and which will much shorten the painful period of prepara- tion, is a hook of the form of the tenaculum, with a shoulder, to prevent its going farther into the globe of the eye than just to permit the point to transfix it. A crooked knife is re- commended for this operation, but it Avill be found a bad exchange for the common scalpel. The disease sometimes returns. It may be expected if the disease has been really cancerous, and if the parts exter- nal to the eyeball'have been the seat of the disease. From the confined nature of the part, the whole soft parts Avithin the bone may have been tainted. If so, it Avill probably hap- pen that Avhen the Avound has gone on regularly towards a cure for some time, Avhen you Avould expect that it Avas about to close finally, it will stop, and instead of merely filling up, a fungus a', ill rise from the orbit. When this has got to some head, the acute lancinating pain in the head will follow. Or if the wound has healed some months perhaps after the ope- ration, hard tubercles will be felt in the surrounding integu ments. Then comes pain striking to the back of the head,, uith burning pain deep in the orbit, and the brain being at fast affected, the patient d'>c. tz EXTIRPATION OF THE EYE. OPERATIONS FOR THE FISTULA LACHRYMALIS. The Fistula Lachrymalis is a disease of the lachrymal canal.—In what may be called its complete state, there is an obstruction of the duct Avhich carries the tears into the nose, and a fistulous sore discharging the tears and pus near the in- ner angle of the eye; the patient only complains of a weak- ness of sight, the eye is Avatery, and on every little excitement the tears fall over the cheek, Avhich is sometimes excoriated, the nostril of that side is dry. But this complaint will not admit of a description in the form of a definition ; in common discourse Ave call all the various degrees of the disease of these passages, Avhich might in a latter stage form an open Aveeping tore, fistula lachrymalis. 1. The first state of disease I shall describe is this: the eye is considerably inflamed and irritable ; the edges of the eyelids are tumid, and the glands secrete profusely ; the inter- nal membrane of the eyelid is very red, and flakes of mucus are seen upon turning doAvn the eyelid ; the integuments over the lachrymal sac are full and puffy, and on pressing these, mucus and pus escape from the puncta. To account for this appearance, there is no occasion to suppose that there is an obstruction in the nasal duct, the disease is general, and all the continuous surface of the eyelids, puncta, sac, and duct; are unusually vascular and spongy. The natural resource against such symptoms is to endea- vour to subdue and counteract this general tendency to a chronic inflammation in the Avhole mucous membrane and ducts. By astringent injections or collyria, the general re- laxation may be removed, and the soreness and SAvelling of the eyelids relieved by the citrine and tutty ointments; then the sac and ducts must be kept also clear, pressing out the accumulated mucus, and injecting into the ducts until the fluid passes into the nose. 2. When there is not only a Avatery eye, and tumid eye- lid, but a distinct tumour of the lachrymal sac and an exco- EXTIRPATION OF THE EYE. 73 riated cheek, something must be done to make the duct per- vious. In this state of the disease, it seems to be ill-judged practice to endeavour to give firmness and resistance to the sac, to make it contract, by cutting open and stuffing it Avith dressing. This is the same as if a surgeon Avould continue to scarify and dress a fistulous sore in the perineum, after he kneAv urine was discharged from it, and that there Avas an obstruction in the urethra. The only questions to be de- termined on previous to the operation are these: 1. Is this a disease owing to a general sponginess and thickening of the mucous membrane ? 2. Has this general diseased state ter- minated in a particular stricture, or obliteration of the lach- rymal duct ? 3. Js there a stricture, or obliteration of the passage Avhich has been the primary cause of the symptoms, and still keeps up the disorder ? But even the answers to these questions are of no great importance, because if an operation is to be done, the entire operation is not more severe, or troublesome, than a more partial attempt to cut into the sac and make it contract and fill up. If it should be found that a more general disease of the membrane prevails, or even if the general affection be proved to be the original cause, this only teaches us to be careful to correct the slight and chronic inflammation of the surface, after the course of the tears is established, and dur- ing the progress of the cure. A great part of this disease consists in the constant excite- ment Avhich the suppurating sac gives to the eye; and that again is a consequence of the absorption still continuing by the puncta, after the duct is obstructed—for if the sac be closed up and obliterated, and there be no disease originally in the coats of the eye, a great deal of the irritation and even the Avatering of the eye will subside—and if the puncta be closed, so will the inflammation of the sac subside, because it has no longer the irritation of the acrid tears. Accordingly it is one kind of operation, attended with much relief of symptoms, to obliterate and fill up the sac altogether. VOL. it. l n EXTIRPATION OF THE EYE. The intention of the folloAving operation, however, is to restore the course of the tears into the nose, and entirely to cure the disease. OPERATION. The patient is placed before the surgeon, and they are both seated. The patient's head is supported on the breast of an assistant, who stands behind him. The surgeon ap- plies his thumb, (in this manner) to the eyelids, and stretch- es them from the inner angle, so that the small tendon of the orbicularis muscle A, is made particularly distinct. Be- ginning his incision by piercing the skin just beloAv this ten- don, he carries his small knife in a semicircular direction, B, (viz. folloAving the curve of the edge of the orbit); raising the point of the knife again, he thrusts it deeper into the up- per part of the incision, and penetrates the sac, and slits it doAvmvards. Or again, if the opening be free enough, it is better to in- troduce into it a small probe, and following the probe Avith a sharp-pointed bistory, to cut open the sac. The next part of the operation is to pierce the bone with the stilette. In piercing the bone, we have, in the first place, to take care that the point of the instrument be lodged within the natural sac before the perforation is made; for if it is not, as I have known it happen, the latter treatment will only- serve to obliterate the sac, and I believe to close the tubes leading from the puncta. Noav, if the young surgeon does EXTIRPATION OF THE EYE. 75 aot perfectly recollect the relation of the os unguis to the nasal process of the upper jaAv-bone, and if he points the in- strument directly into the nose, he may chance to hit upon the very strong process of the maxillary bone. But if after being fairly in the natural sac, and of course Avith the point beyond the sharp ridge of the maxillary bone, Avhich forms the margin of the orbit toAvards the nose, he carries on his point obliquely downAvard and inward, he comes to be op- posed only by the thin plate of bone, (as delicate as a piece of paper), Avhich is called the os unguis, and now he will find this part of the operation very simple indeed. By keeping the side of the instrument pressed upon the nasal process of ef the maxillary bone, and carrying the point for Avar d it Avill pierce this thin lamina of bone the os unguis, and then the point should be more turned toAvards the cavity of the nose, so as to enter it just before the lateral cells of the eth- moid bone and above the lower spongy bone. That we are right in the direction of the instrument, is known from the very slight resistance Avhich we meet Avith, and the floAving of a feAV drops of blood from the nostril, or which may fall into the throat, according as the head is thrown backAvard or fonvard. The instrument being AvithdraAvn, a piece of leaden wire is introduced. This, being Avorn for a week or a fortnight, is taken out and replaced by a piece of bougie. In the course of tAvo months, Avhen the passage is become like a na- tural canal, the bougie is Avithdrawn and the wound al- IoAved to heal; and the tears Avhich have been all this time absorbed by the puncta and carried into the sac, and have passed by the side of the bougie into the nose, continue, up- on its being AvithdraAvn, to run by this new passage into the nose. The perfection of the cure is ascertained by the eye having no more than its natural moisture, and that side of the nose Avhich was before dry having now as moist a dis- charge as that of the other side. The following is the method of Mr. Ware .-—Having open- ed the sac, or supposing that it has been opened by ulcera- 76 EXTIRPATION OF THE EYE. tion, he introduces the blunt end of a probe, (of a size rather smaller than the common dressing probe), and pushes it on gently and steadily in the course of the natural duct. He overcomes the obstruction by force, and he passes the instru- ment into the nose by the nasal duct*. The probe being AvithdraAvn, a small silver style of nearly the same size of the probe, and with a flat head, which is to prevent its sinking altogether into the nose, is now introduc- ed, and the operation is finished. This little style, passed doAvn into the nose, keeps the duct permeable, A\hile its head being covered a\ ith black Avax, or a bit of court plaister stuck upon it, has every appearance of a common patch. This operation is ingenious, Avhilst its simplicity ensures success. It is not followed by the high inflammation and quantity of matter Avhich will sometimes follow the use of the bougie, and does not therefore endanger the closing of the upper part of the sac or puncta, while from the begin- ning there is neither confinement nor unseemly dressing re- quired. Few people, liOAvcver, will submit to a palliative remedy, such as this operation is, Avhen it is intended that the style shall remain in the nose, and if the operation be performed Avith the intention of removing the style, and closing the sac, I Avould recommend that it should be performed as first described, viz. by piercing the os unguis, and then sub- stituting the style for the bougie, with the expectation that the patient will submit longGr to its use. By this means Avhile the patient enjoys comfort during the cure, he has the better chance of its being perfect in the end. When we perform the operation by Avearing the leaden wire and bougie, or perform it in Mr. Ware's method, Ave must withdraAv the bougie or .style, and wash the passage by means of the small syringe; at first every day, after- wards only occasionally, as it may seem to be required. * The full descent of the point of the probe into the n»se will sijufc the instrument fully an inch and a quarter. EXTIRPATION OF THE EYE. V This prevents the lodgment of matter, and the formation of abscesses. From Avhat has been said, it Avill readily be understood that during the cure we must carefully attend to the state of the conjunctiva, and the general secretion of the eye. As we have already hinted, there was formerly a method practised, the object of which was to fill up the abscess Avith granulations, and entirely to obliterate the sac, treating the disease like a common abscess. This, on first thoughts, would appear to be a method of increasing the evil, but a great part of this complaint of fistula lachrymalis arises from the excited state of the lachrymal sac and ducts, Avhich pro- duces, by sympathy, an irritation of the eye and of the lachrymal gland. There may occur ulceration and much internal disease in the part, Avhich may make us still prefer this method to the long continued use of the bougie or the introduction of a style. Where the ducts are merely obstructed, there is only an occasional Aoav of the tears over the cheek, Avhen the eye is accidentally excited. The patient complains little of the disease until the sac inflames; and I knoAv there are cases of the common operation producing abscess, followed by total obstruction, without the patient having an idea of any fail- ure in the operation he has suffered. Scarpa has thought it necessary to recommend in a parti- cular manner, that the sac should be dressed with escharotics to the bottom. I have always seen that the presence of the bougie in the passage was sufficient to inflame and cause the due contraction of the sac. He has thought it necessary too to recommend the use of the actual cautery, to destroy the os unguis, Avhen a new passage is to be formed; a thing which I think I can say with confidence, is never necessary, and must be kept altogether out of the enumeration of our resources. 78 OF THE EAR. CHAPTER 11. OF THE EAR* Matter Avhich Aoavs from the ear may be a mere change of secretion in the glandulas ceruminosae. In this case we may inject any mild astringent, as lime Avater, for cleanliness, and anoint the passage with the diluted citrine ointment. Sometimes the passage ulcerates, and there is a great puru- lent discharge from the ear, or after some occasional increase of the inflammation, an abscess or sinus forms behind the tube of the ear. The following consequences may ensue from this suppuration. 1. The thickening of the membrane of the tympanum. 2. The growth of fungous excrescences from the passage. 3. The destruction of the membrane of the tympanum by the progressive ulceration. 4. The communi- cation of the inflammation and suppuration to the cavity of the tympanum. We must then in suppuration keep a free outlet to the matter, by preventing the SAvelling of the tube from closing the passage, and by opening the abscess if formed by the side of the tube ; Ave must prevent the lodgment of the mat- ter by every possible attention. Our injection should be some mild fluid at first, and afterwards Ave may endeavour to cor- rect the diseased surfaces: for this purpose a common injec- tion is the muriate of mercury with lime Avater. If the hearing be dull to all outAvard sounds, but increased to all vibrations of the head or javrs, and there is a confused and loud noise often heard, there is probably only an adher- ence of tough mucus, about the opening of the Eustachian OF THE EAR. 79 tube into the throat, or perhaps an inspissation of the ear-wax, which b6th prevents the sound from entering the tube freely, * and by pressing on the membrane of the tympanum prevents the free motion of the membrane. In this deafness from the inspissated wax, we need only wash out the tube with a sy- ringe and tepid Avater. When the Eustachian tube has been obstructed by a disease in the throat, deafness is the consequence. It is in this case that it is proposed to puncture the membrane of the tympa- num, that like the hole in the side of a drum it may give free- dom to the contained air, and free play to the membrane of the drum ; the perforation becomes a substitute for the Eustachian tube. The patient is placed Avith the ear toAvards the direct light of the sun ; the surgeon is behind him, and he turns the head until the light is admitted into the bottom of the tube. The point of the silver probe, (a small stilette is used by Mr. Cooper), is pushed through the loAver and fore part of the membrane of the tympanum. As it is found that the perfo- ration in this membrane very soon heal=, it has been thought necessary to lacerate it pretty freely, but the greater the in- jury the greater is the probability of the membrane inflaming, becoming thick, and of consequence, incapable of delicate vibrations. I should imagine that it Averc better for a time to alloAv a small probe of silver to remain in the passage of the ear, supporting it by a little cotton in the passage. It is an operation of great uncertainty, and leaves the patient to re- gret the very short enjoyment of the benefit he has been led to expect from it. But I deem it to be of more consequence to speak here of the dangers of deep suppurations in the cavities of the ear. Suppuration may take place in the cavities of the ears, and in the mastoid cells, either from the communication of inflam- mation from the outAvard tube, from the throat, by the Eus- tachian tube, or it may be a scrophulous disease, originating in the bone itself.' Any one who thinks of the principle of Pathology, which guides us in our surgery of the head, must 80 ©F THE EAR. at once foresee danger from suppuration and caries of the temporal bone, for though it contain the organ of hearing, yet it takes more importance, in this instance, as a bone of the cranium. The worst character of the disease is when, after the patient has had violent pains, he is attacked with shivering and fever,' and the organ is destroyed, and the passages of the ear are full of pus, and the bones of the tympanum have come away. This discharge may continue long, without any further appa- rent bad consequences than the loss of the organ, but if there comes drowsiness, and oppression, and a feebleness or degree of paralysis in the opposite side of the body, then the petrous portion of the bone is carious, the dura mater attached to it has partaken of the disease, and the side of the cerebellum and base of the cerebrum are diseased and covered with pu- rulent matter. The abscess sometimes forms in the mastoid cells, and mak- ing a slow progress, such as characterises the scrophulous ac- tion, after a time the tumefaction of the integuments over the mastoid angle of the bone betrays its presence. The bone in some instances becomes carious, and the finger can depress the integuments into the bone, and, when this is opened, it is not merely a disease of the bone which Ave diseover, but the sur- face of the brain is exposed, and the probe can be introduced deej>er than the thickness of the temporal bone ; a circum- stance Avhich sheAvs the danger of the experiment. Thrice I have seen such suppuration fatal by the communication of dis- ease to the brain, before the spoiled bone gave Avay outward- ly ; and I have ascertained the nature of the disease by dis- section. We learn from this view of the subject, hoAv carefully we ought to attend to symptoms when there is disease in the ear, lest it should become irrecoverably bad, and end in communi- cating the disease to the brain. We must bleed, and purge, and foment, to allay the pain and inflammation, if it be active. Blisters are to be applied behind the ear, if a sIoav continued action is proceeding within; and where we can ascertain that OF THE EAR. $1 there is caries in the posterior angle of the bone, Avith dan- ger of the confinement urging the progress of the diseased action to the brain, we have to apply the trephine and pen& trate into the cells of the bone; even Avhen this is done, if the petrous portion of the bone be carious, there remains only a hope, that by great care, soothing the action, and guarding against the matter collecting, we may gain time, so that the diseased bone may separate, and an abscess in the brain be prevented from forming. VOL. II. M 82 OF THE PSOAS ABSCESS. CHAPTER HI. OF THE PSOAS ABSCESS. In the treatment of sinuses and abscesses, the most es- sential point to be known is, what has produced the collec- tion of matter, and Avhether the cause be removed—for if we are to cut up fistulae during their tendency to form, we shall find that only deeper and larger passages open themselves. If vre are to open an abscess, Ave ought first to consider by Avhat means Ave are to produce a change in the action of the part. The matter of an abscess is not collected, but, like the fluids of the cavities of the body, it is suffering a change; the absorption of the pus is performed at the same time that pus is throAvn out by the vessels; and the increase or dimi- nution of the matter of the abscess depends on the relative action of the arteries or absorbents. We have to observe Avjiat further change, besides evacuation of the matter, is ac- complished by opening an abscess. Experience teaches us that a scrophulous abscess will seem to point, being soft and prominent, and having fluid evident- ly in it; and yet that Avhen the lancet is thrust into this tumour, only a pale Avatery fluid escapes, and the walls of the tumour acquire an inelastic, but irregular, firmness, like a cake: and the progress of the action, or at least the soften- ing of the tumour towards the surface is not promoted but checked. The scrophulous action is here, I suppose, of a slow and sluggish nature, and the phlegmonous action, the consequence of the wound, has somewhat of a contrary ten- dency, so that the original progress of the disease is not pro- moted, OF THE PSOAS ABSCESS. 83 Again, in the scrophulous action about joints Avhich has produced abscess, by cutting into this abscess the sIoav na- ture of the disease is changed; the matter, though evacuat- ed, collects again, no longer bland or mild, but putrid and acrid, and an irrecoverable caries may be the consequence*. It is of little importance Avhether the change in this par- ticular instance is to be attributed to the air getting access to the secreted matter, and producmg an alteration upon it, making it acrid and stimulating; or whether the incision changes the nature of the action in the surface of the caA-i- ty, so as to produce bad and foetid matter. But it is par- ticularly of consequence to observe this contrast, that by stimulating the surface and making counter irritation on such a scrophulous joint, the original action might have been changed, and the limb and patient saved ; Avhile under this surgical treatment the disease has rapidly advanced. Where an abscess or extensive fistula forms, in consequence of a wound, it may be permitted to rouse the activity of the surface by an injection or seton, for perhaps there is nothing peculiar in the action ; there is only a Aveakness and inactivity ; and by habit the secretion continues.—But even here it Avill in general be better to raise the life and activity of the whole limb, by admitting freer motion, by warm stimulant fomentation and rubefacients.—For though these communications and abscesses have formed after an injury, it by no means follows that they are merely the consequence of that injury ; they have often a scrophulous action; and the injections or seton raise a violent inflammation, and ge- neral tension of the limb, which instead of promoting the adhesion of the cavities form others in succession. All abscesses or fistulae connected av ith ducts or natural passages form a class by themselves, which ought not to en- * Experience teaches us that it is useless to open scrophulous and venere- al abscesses ; but further, we find the practice bad as complicating the case, and dangerous as sometimes productive of the phagedenic ulcer. Read the section on abscess in Ford's Observations on the hip disease, which is very valuable 84 OF THE PSOAS ABSCESS. ter into the present inquiry. Such are fistula in ano, fistula lachrymalis, fistula in perineo. In these the difficulty of discharging the natural fluids, produces an inflammation in the ducts ; abscess forms by the side of the passages; and a communication is made betwixt the duct and abscess by ul- ceration, and an irritation is kept up; until the passage be freed the abscess a\ ill not heal. WTiere an abscess is very large, there is one circumstance requiring particular attention ; it is this, if the abscess burst, that is, if the ulceration proceeds outwardly to the skin, the Avhole surface of the abscess will inflame, the discharge Avill become bad, and the patient will die. We open such ab- scesses, not with the intention merely of evacuating the mat- ter, nor for the purpose of procuring an adhesion and ob- literation of its sides, but to alloAv the cavity gradually to contract so that A\hen it fills again it may not be so extensive nor apt to disorder the system Avhen it is finally opened. For example, if a large abscess be pointing, and about to ulcerate and burst, it is to be punctured, and the matter evacuated; but it is not to be lanced just upon the most prominent, and thinnest part. The opening should be made by the side of that part of the abscess Avhere it naturally may be expected to open. The opening is thus to be made in the healthy skin, so that the Avound may close again Avith- out any ulcerative action taking place, and without the risk of inflammation being propagated over the sides of the cavi- ty. From the evacuation of the matter, and contraction of the cavity, the Avails of it thicken. When the cavity fills again, it is less extensive; it is to be punctured again, and the opening immediately closed ; the abscess still further con- tracts, and perhaps by the third or fourth opening the ab- scess is so much diminished that no care need be taken to close the opening; it may be left to common treatment. These introductory observations Avill be found necessary to the understanding of the short statement I am now to give of the nature of the lumbar abscess, and the treatment of it. OF THE PSOAS ABSCESS. 85 PSOAS, OR LUMBAR ABSCESS, CONTINUED. The Psoas Abscess is tlie consequence of a sIoav and almost imperceptible inflammation of tlie cellular membrane, by tlie side of the lumbar vertebra;, and around the psoas muscle*. These deep parts, from their nature as Avell as their situation, being little sensible, and the disease being a sIoav, scrophulous action, the nature of the complaint is only suspected Avhen there is a weakness in the loins, a numbness and Aveakness of one thigh, and a dull Avearying pain in the loins like rheuma- tism ; nor is there at first general symptoms to mark the diag- nosis more distinctly. Sometimes the pain in the loins is very severe, with a total inability of raising the thigh. But AAhen a compressible tumour appears in the groin, the fluctuation is perceptible in the tumour, and pulsation is felt in it Avhen the patient coughs; then the nature of the case is too evident, and the surgeon has that painful conviction of a patient being in the utmost degree of danger, Avhile he is little conscious of it himself, and but imperfectly comprehends hoAv a matter so trifling in appearance, and so little troublesome, is pregnant Avith so great evil. If there precedes or accompanies the appearance of ab- scess at the groin, a curvature of the spine, the prognosis is still more unfavourable, for caries of tlie bodies of the ver- tebrae is sometimes the origin, or at least, the precursor of the psoas abscess. As might be naturally expected, especial- ly Avhen the disease is complicated Avith a caries and sinking of the spine, the abscess sometimes makes its Avay outAvard upon the loins, forming a tumour by the side of the spine. If the tumour in the groin is opened, and the matter of the abscess evacuated, the sac inflames, the loins become Aveak and painful—rigors, a rapid pulse, Avhite tongue, and * The abscess is sometimes in the centre of the psoas magnus. This dis- position to form abscess in the centre of the larger muscles, I have seen very generally prevailing; on dissection, I have found them in the psoae, the gas- trocnemii. and in the muscles of the thigh. 8(3 OF THE PSOAS ABSCESS. hot skin succeed—the discharge becomes thin and foetid, and often profuse, the appetite entirely fails, the nights are rest- less, and a rapid hectic is confirmed. The cure is to be thus conducted:—1. To evacuate the matter and yet endeavour to prevent the inflammation of the sides of the abscess. 2. To produce a counter irritation by an artificial ulcer on the loins. 3. To correct or change the action, or produce an absorption of the remaining matter by emetics or by electricity. If the abscess has formed a tumour in the groin, and the fascia be yet entire, and the integuments on the promi- nent part of the tumour thick and not yet possessed of much increased vascularity, the abscess lancet is to be thrust into the most prominent part, a little slantingly through the skin; but if the tumour be threatening to burst, Ave should punc- ture it not on the highest part, but more towards the base of the tumour, so that the opening be made in sound skin, which will more readily close and heal. When the pus and coagulable matter are evacuated, the Avound must be treated tenderly, united by a small piece of piaister, and bound doAvn with a soft compress and band- age. We must be careful that nothing intervenes betwixt the lips of the Avound, that the union of the skin may be se- cured ; and by the compress the integuments are pressed up- on the fascia of the thigh, so that the opening through it is closed also, and the matter of the abscess prevented from passing under the skin. The patient for a time must be con- fined to the horizontal posture, and use no exertion in rais- ing himself, or in moving the abdominal muscles. When the small Avound is healed, then more freedom is al- lowed to him, and gradually the tumour appears again. When it has acquired a size and prominence sufficient, it is to be punctured a second time and healed; and this successively until the matter evacuated be no longer considerable. When only a few ounces are evacuated, and the state of the pa- tient is favourable, Mr. Abernethy leaves the puncture open, being no longer solicitous to prevent the inflammation of the OF THE PSOAS ABSCESS. 87 sac; or rather it is better to endeavour to cause an absorp- tion of the remaining matter of the sac, by giving emetics and sending the electric spark through the loins and side. If there should occur much debility during the cure, bark and wine and free air will do much; and opium with the bark will be required if there be much irritation in the sac or diarrhoea. Another resource for correcting the internal disease in the loins is the formation of issues by the side of the vertebrae, as for the disease of the spine; and this treatment is parti- cularly necessary when there is a tenderness on pressing the spines of the vertebra?, or a degree of curvature of the spine accompanying the abscess. It is to Mr. Abernethy that we are indebted for this plan of treatment of the lumbar abscess, Avhich affords us hopes of curing a disease before considered fatal. 3& OF THE CURVED SPINE. CHAPTER IV. OF THE DISEASE AND INJURY OF THE SPINE. OF THE CURVED SPINE. 1 his term does not include the distortions of the spine, from rickets or mollifies ossium, but that only which is the consequence of an ulceration and Avasting of the bodies of the vertebra?, a disease most frequent in the lower vertebra? of the back. In an infant these are the symptoms: the mother tells you that the child was strong and healthy, and perhaps that he had begun to use his feet, and could stand upright with little assistance, but that of late he does not try to stand, and Avhen laid over her knee, he does not struggle as children naturally do Avith their feet. You find the child's flesh soft; and par- ticularly the skin and muscles of the loAver extremities, soft and Avoolly; upon examining his back, you find one or tAvo of the spinous processes of the vertebras particularly prominent. If the child be old enough to have walked, he is gradually deprived of the use of his legs; he complains of languor and fatigue; he is listless and unwilling to move ; his legs are apt to cross, and he stumbles often, being unable accurately to direct the foot. He leans forward, and there is a projection in the spine. Large abscesses sometimes form and drop doAvn upon the loins, and appear externally in the top of the thigh, or a tumour is formed by the side of the vertebras of the loins. OF THE CURVED SPINE. 89 in the latter stage of the disease there is pain of the back or loins, which even in bed is tormenting and incessant; the breathing, and indeed the whole functions of the thoracic and abdominal viscera, are oppressed by the chest falling down in consequence of the great curvature of the spine. The urine and faxes are passed insensibly, and in consequence of this perhaps as much as by sitting on the insensible buttocks, (the perpetual pressure on which gives no token of the degree of injury they sustain), deep sloughing or horrible ulcers take place. This is a scrophulous disease, which begins in the bodies of the vertebrae of the back or loins. By dissection I find that the first stage of the disease is not an increase of vascularity and softening of the bodies of the vertebrae, so that they sink under the weight of the body; but the progress of the de- struction of bone proceeds by the entire absorption of several intermediate portions of the body of the vertebrae, leaving the spine supported by the remaining firm parts, which are some- times like columns standing betAvixt that which is decayed. (I have given a plate of this early appearance of the disease). The destruction of the bone having gone thus far, the affected bodies of the vertebrae sink under the incumbent Aveight of the head, chest, and arms. The paralysis of the lower extremities is noAv for the most part distinctly marked, but as I have seen this symptom before the sinking of the vertebrae, I have concluded that the neighbourhood of the dis- eased bone has involved the spinal marroAv in the morbid action, so that its function has suffered.—The cessation of the disease relieves the paralysis; which is accounted for by sup- posing that the spinal marrow and the tube of the vertebrae become adapted to each other ; but the circumstance is equally well explained by supposing this to be the result of the cessation of the diseased action. In a young person who has shot up to great height, and whose muscular strength is not great, there is a possibility that a curve of the spine may arise from a bad habit merely, but these curvatures are generally lateral. In th«» tru* dfc- A'OL. IT: V 00 OF THE CURVED SPINE. ease, the pain or uneasiness deep in tlie spine, with that coun- tenance and habit peculiar to scrophula, will urge us to exa- mine the spine, and if Ave should not find that there is a be- ginning prominence in the spinous process of one or tAvo of the vertebrae, yet by pressing Avith the fingers along the spine, some one of the spinous processes Avill be found to give pain perhaps, and in this case we should not delay the remedy*. The grand remedy for this disease is the making of issues or setons by the side of the affected spine. But I cannot think that the good effect of these artificial ulcers is from their acting as drains. I see them lose their effect when they be- come stationary ; I see, even in the first violence of the irri- tation and inflammation, a remarkable change on the disease for the better, Avhich does not continue if the surrounding skin and deeper part lose their inflammatory action. Once I found quick and remarkable relief given by the caustic eating much deeper and broader than I intended or thought right; and I have on another occasion Avitnessed the remarkably good effects of the hospital sore catching the issue, and destroying the soft parts to a great extent.—In this last instance the healthy inflammation Avhich succeeded the sloughing of the sore made an immediate change on the disease, and the patient got quite well. In short, I conceive that the inflammation excited in the neighbourhood of the disease, (Avhich is of the nature of a slow and sluggish scrophulous inflammation), invi- gorates these affected parts, and reaching even to the vessels of the bone changes the nature of their action, and restores the natural influence. In this vieAv I prefer the making of issues Avith the caustic of a longitudinal form by the side of the curve of the spine, first one, and when the surrounding inflammation is contract- ing, and the ulcer likely to become stationary, I make anoth- er in the other side of spine, for a time neglecting the first; and afterwards I conceive it necessary to keep up a considera- ble degree of irritation in the one or other of the issues. I * See Sir James Earle, On the Curred Spine. OF THE CURVED SPINE. 91 believe pain, or in other words irritation, to be absolutely ne- cessary to the effect, and I cannot prefer the seton to the caus- tic because it giAes less pain. If the child he young, it will only he necessary to take care that he be not carried in the usual way in the nurse's arms, but lie horizontally. If tlie child be more advanced, it is of the first importance that the spine be supported, and tlie weight of the upper part of the body taken from the diseased vertebrae. For this purpose, Le Vacher's apparatus is the best. But I may remark upon this subject, that our object should be to support, not to stretch the spine. If Ave find that by an apparatus we can elevate the verte- brae which have sunk, yet this should not be done, for the final cure is to be obtained by the anchylosis of the vertebrae; if they have been once destroyed, and have sunk, to separate them is to prevent the natural process of cure. Here, as in most cases, pain is the indication of mischief, Avhile relief from it gives hopes of an amendment; noAv a\ hen we see a poor creature moving Avith much distress, seizing on every object for assistance, and leaning with his hands on his thighs to give relief to the pain of the spine, how can Ave doubt but that to take off ihe pressure of the head and chest will promote the cure. The success of our endeavours to cure this disease in the spine, is to be judged of by the allaying of the complaint of pain, or of fatigue of the loins; by the sleep and appetite be- ing good ; by the ceasing of involuntary spasms of the limbs, the flesh of the thighs and legs being firmer to the feeling; lastly by the diminution of the curvature of the spine, and by the patient perceptibly growing taller. I am naturally called upon here to say a few words on rest, and its absolute necessity in this, and in many other diseases of the bones and joints. Those who are bedridden are gene- rally suffering from disease, and the weakness induced by the disease is attributed to the confinement: but the contrary holds good Avhen the disease is of a nature to be relieved by 92 COMPARISON BETWIXT THE SCULL AND SPINE. rest; for then lying in bed restores the patient: under the confinement he gets fat instead of wasting. Lying in bed is too often a confinement to bad air, the breath and exhalation; are confined, and a free circulation of air is not admitted. But if, on the contrary, the person confined to bed be cheerful and not despondent, and if he be as careful to change his ap- parel and bed-clothes, and to wash, as if seeing company, and to eat and drink in the moderation proportioned to the little exhaustion or exercise Avhich his situation allows of, he will get fat and enjoy health. In very bad cases of distorted spine, therefore, I conceive that it Avill be better to keep the patient in bed or on a sofa, until there be a favourable change in the disease, and that when the anchylosis has formed, or the diseased vertebrae con- solidated, the patient may have the relief of moving about un- der the apparatus for supporting the spine, until the cure is established, That part of Pathology which explains the diseases of the spine, and the effects of injuries of the vertebrae, is very im- portant. We find the spine to be a column composed of many bones jointed and united by ligaments. We find that Avhile the column has to support the weight of the head and trunk, it is at the same time capable of a certain slight de- gree of motion betwixt its individual bones. Above all Ave can never forget that is a tube protecting a prolongation of the brain, the spinal marrow. We find that besides the tube of bone, the spinal marroAv is surrounded Avith a sheath, as a further protection. Considering these circumstances, Ave see a strict analogy betAvixt the effects of disease and injury of the vertebrae, and of the skull; in both instances the high importance of the subject results from the nature of the contained parts. The brain suffers concussion in every shock given to the head; compression and injury from fracture of the skull; in- flammation and suppuration from disease or death of the bone or of surrounding membranes. So does the spinal mar FRACTURE OF THE SPINE. 9? tow suffer from a blow on the spine: so is it bruised or compressed when there is fracture of the tube of the verte- brae : so is it inflamed or compressed when there is caries of the bone or disease of the membrane; while it is exposed to further injury by dislocation of the vertebra?. OF FRACTURE OF THE SPINE. T have had an opportunity of examining by dissection only one instance of fracture of the body of the verte- bra. The bodies of the vertebrae are not fractured by blows, but by falls, in AAhich the whole body is twisted, or when a bank of earth falls upon and buries a man. This fracture will not be known by the crepitation like a common fracture of the limbs, but only by the derangement of the projecting spinous processes ; while yet they are not separat- ed as in dislocation, nor crushed and crepitating as Avhen they are themselves fractured, or a blow upon them has crushed in the arch of bone. I have given above, a sketch of the parts in the instance I examined, and it is seen how the body of the vertebra at A is broken, Avhile the intermediate tough and ligamentous sub- stance B is entire; it will be seen too how the point of the bone C is forced against the spinal marrow D. The crush- % fracture of the spine. ing of the bones hurts the soft substance of the spinal mar- row, although it appeared entire, being covered with its tougher sheath. I believe that the force which fractures the bone will at the same time destroy the spinal marroAv, and the effect will be paralysis of the loAver extremity, and in the end death. The substance or bodies of the vertebrae may be said to be fraetured when a bullet lodges there. Gun-shot fracture is a desperate and generally fatal case; for if the ball has entered from before, it must have passed through the visce- ra of the thorax or abdomen, and if from behind it must have injured the spinal marrow. If it has entered by the side into the bodies of the lumbar vertebrae, it niay lodge there Avithout being fatal, and may drop from its place af- ter inflammation and suppuration have reduced the patient; but the chance is, that by the concussion of the spinal mar- row or breaking up the tube of the spine into splinters, the injury will prove quickly fatal. If the spinal marrow be cut through by a bullet, a man may live a longer or shorter time, according as the divi- sion has been made in the loins or higher, as in the neck. If the division has happened in the loins, there may be Inly paralysis of the loAver extremities, and insensibility of the bladder and rectum. If higher up, the bowels will suffer more by distension. If the division has been made high in the neck, the patient will die suddenly from the supply of nerves to the muscles of respiration being cut off. Besides fracture of the bodies of the vertebra?, and frac* ture by gun-shot, there may be fracture of the arch of the vertebra, Avhich forms the tube for the spinal marrow. A man falling backward and having his spine curved and pro- jecting, may, by hitting a stone, fracture and beat in the arch of bone; or, supposing that he is driving a carriage under a gateway, stooping, thinking to avoid the arch, hut does not, he strikes the same part of the chain of spinous processes against the arch, then the blow breaks the tube of the vertebrae and forces in the tube and spinous process, so FRACTURE OF THE SPINE. 95 that he becomes paralytic in all the lower part of the body. In whatever way the vertebrae are broken, the danger of moving the body must be apparent, since in every change of posture, or turn of the body, the broken bones may be thrust against the spinal marroAv. Looking to the anatomy as our only guide, AVe see no reason why in fracture and de- pression of the tube of the spine, the surgeon should not make an incision, and draAv out the fractured portions, and el- evate the arch! But when we turn our attention to the real circumstances of the case as it has actually presented itself in practice, we find the bones have been crushed, the swelling general, and the paralysis complete. If this paralysis prov- ed that a piece of bone stuck in the spinal marroAv, then we might proceed to operation. But as a blow less than suffi- cient to crush the spine will by concussion produce the pa- ralysis, we are tempted to wait and hope. But if the bones are evidently crushed in upon the spinal marrow, then raising the bone Avill not remove the injury to its substance. In short, the uncertainty of the circumstances of the case, joined to the little probability that the operation would do good, supposing that the bone has been crushed upon the spinal marroAA', or has entered its substance, deters us from laying open the canal, the more especially as Ave have the chance of doing more mischief than good. When called to a patient in this situation the 6urgeon car- ries a catheter Avith him to draAv off the urine, because he knows that the sensibility of the bladder is destroyed, and that there will be in a short time, an accumulation of urine. There will come flatulent distension of the abdomen too, and vomiting or hiccup, for which (in this case) terrible symp- toms we have only to palliate by ordering very stimulating clysters, and frequent friction of the belly. If the patient survives the first shock, the insensibility of the hips and lower extremities will allow him to lie pressing the hips and nates till they mortify. This mortification and ulceration on the sacrum may be accelerated by the insensible discharge 9t> DISLOCATION OF THE SPINS. of faeces or the dropping of the urine, and consequent moist- ure of the bed. After this the patient soon sinks. OF THE DISLOCATION OF THE VERTEBRA. Dislocation cannot take place in the vertebrae of the back and loins, I imagine; from the circumstance of the ligamentous connexions being fully stronger than the bone. But a species of subluxation may certainly take place in the lumbar vertebrae. This is a dislocation of the articulat- ing processes, but not of the bodies of the vertebrae, the intervertebral substance being only a little irregularly stretched. This derangement of the bones may be a consequence of the distortion of the body in Avrestling or tumbling, or by a weight falling on the shoulders, when the body is bent for- ward. By this means the ligaments already stretched are toai up, and the vertebrae stand thus:— Plan of dislocated Vertebra;. A, the articulating process of the upper vertebra. B, the articulating process of the lower one. These, it will be observed, should lie flat on each other, instead of which their points stand opposed, so that the bodies of the verte- DISLOCATION OF THE SPINE. 07 brae C D cannot come into their regular approximation, but stand Avith oblique surfaces. From what is here expressed the symptoms Avhich cha- racterise the accident may be learned. The person is bent doAvn, and unable to elevate himself; there is a projection of the spine, and there is an unusual space betAvixt tAvo of the spinous processes. The reduction of this dislocation is by no means easy to accomplish. We cannot turn and twist, nor yet stretch the body, as Ave Avould an arm or leg. Wras our strength equal to it, there is danger, Avhere Ave have the soft spinal mar- row Avithin, and Avhere the strong connexions of, the process- es are already lacerated. The older surgeons have recom- mended that the patients should be put over a barrel, and that the body be then bent forAvard until the processes of the vertebrae are disentangled. It has happened that after all methods have been tried in vain, the patient has been relieved by an accidental jolt or exertion, and the bones have slipt into their places. When the reduction has not been accomplished by the efforts of the surgeon, yet in length of time and by degrees, the spinous processes have approached, and the patient has regained tlie erect posture. Dislocation, I imagine, cannot happen in the vertebrae of the back, becaoae of the firmer articulation of the processes^ and the strength of their attachment by the double articu- » Iation of the ribs. But Ave may have subluxation in the vertebrae of the neck. A man, having slid off a hay-stack, fell on some loose hay that covered the ground; the skull Avas not injured, but he never recovered the shock, and died of the concussion. In this man I found that I could intro- duce my fingers betAvixt the third and fourth vertebrae of the neck; and on opening the tube of the vertebrae a great quantity of fluid blood flowed from the spine and base of the skull. These, I believe, will generally be the circum- stances attending the subluxation of the vertebrae of the neck, viz. that the shock of the head and spine will destroy the VOL. II. O lJ8 DISLOCATION OF THE SPINE. patient and that the symptoms of concussion will be aggra- Abated by the blood effused from the ruptured vertebral veins. But another effect may be the result of a lesser degree of injury to the ligaments of the spine, when the neck is thus tAvisted under the pressure and falling of the body. The Avhole soft parts around the bone, and Avithin the canal of the vertebrae, may be so injured that there may arise a thickening of the sheath of the vertebral canal, and conse- quent pressure of the spinal marrow; or I have thought that the injury to the spinal marroAv may produce a slow disease in it* Avhich at last destroys its function, and makes all the body beloAv paralytic. If a train of symptoms, ush- ering in paralysis, should succeed to a twist of the spine, or to any kind of injury, Ave shall be led to employ all such means as are proved in caries of the spine to be effectual for removing the deep-seated disease. DISEASE OF THE KIP JOINT. *.»9 CHAPTER V. OF THE DISEASE OF THE HJ.P JOINT 1 ins is a scrophulous disease.—It is most common in youth, from childhood to the twenty-fifth year; but the same disease attacks those of sixty years of age. The disease begins with a deep-seated pain behind the trochanter major; the pain being aggravated by motion, the patient, in Avalking, throAvs the Aveight of the body on the opposite side, and there is consequently an aukward crippling gait. Exercise, we are told, in the beginning of the disease relieves the pain, but it U aggravated in the stiffness after fatigue. When the disease is formed, and Avhile yet in its first stage, the limb is lengthened. This is not merely a feeling of greater length in the limb, occasioned by the inflammation and increased sensibility of the parts Avhich form the hip joint, but there is a filling up of the acetabulum, and a pro- trusion of the head of the thigh bone from its socket. During this progress of the disease, there is as yet no dis- colouration of the skin ; but the hip is swelled over the joint, and, from Avant of use, the muscles of the hip are flabby. The trochanter major is prominent, and in consequence thi hip is increased in breadth. Dr. Falconer observes, that there is to be felt an enlargement and projection of the tube- rosity of the ischium as well as prominence of the thigh bone. With the Avant of exercise the leg and thigh Avaste, and, in the advanced state of the disease, the limb instead of beJnp, longer is considerably shorter. The difficulty in the motion of abduction or throAving the leg out sideAvays is considerably greater than that which is felt in moving the limb in any 100 DISEASE OF THE HIP JOINT. other direction. This is owing to the relation of the bones, or entire dislocation of the femur. There is a peculiarity in the seat of the pain, too, which must be held in remembrance, else Ave shall be employed in fomenting the knee and leg for a disease in the hip, I have found a disease of the nerve in the ham, producing pain in the sole of the foot, continued for nearly tAvo years. So I believe that in this case the ischiadic nerve passing so near the seat of disease, is affected, and pain is the consequence, Avhich is attributed to the outside of the thigh, the knee, and leg. When the pain is deep in the groin and in the inside of the thigh and knee, it is probable that the obturator nerve may be involved in the inflamma- tion. When suppuration takes place, there are startings and catchings during sleep. The pain is increased, with much tension and throbbing ; noAv the skin inflames, and the abscess bursts either in the groin or behind tlie trochanter. Succes- sive abscesses will sometimes form around the joint, and still the patient survives. The limb being fixed, the granulations of the inflamed joint run together, they ossify, and an anchy- losis is formed, But often, the abscess advancing, and the skin being in- flamed, hectic fever rapidly reduces the patient, there is per- spiration, diarrhoea, a white tongue, a face changing from the hectic flush to the leaden coloured paleness of those who are tabid; they linger thus, and die. This hip disease is an inflammation peculiar to the scro- phulous constitution. It attacks the ligaments and cartilage in the parts jjpjoying a Jess active and vigorous circulation. There is danger of its being confounded with rheumatism, gout, or the psoas abscess. As to the cause, it is scrophulous disease. The bones and joints of the lower extremity are most liable to disease, and of these chiefly the larger joints : therefore the knee is most liable to disease ; next in frequency is the hip joint; then the ancle joint. j DISEASE OF THE HIP JOINT. 101 Dissections prove that the cartilage is absorbed, that the bones of the pelvis forming the socket, and the liead and neck of the thigh bone are Avasted and carious; or after the inflam- mation of the bone, and the Avasting of the cartilage, the bones unite and form an anchylosis*. Anchylosis is not necessarily the cure of the disease, nor a natural termination to it. I believe it takes place thus:— The inflamed bone not being under the influence of that "law which contracts and directs the growth of parts in their na- tural action, irregular processed are formed, Avhich, pioject- ing, hinder the motion of the joint; by the loss of motion the incessant irritation of inflamed parts, moving on one ano- ther, is taken off the joint, the latter being now preserved steady; the bones unite; and the surrounding abscesses be- ing no longer festered by the pain and irritation Avithin, they are contracted and dry. / In the cure, I have advised repeated small mercurial purges, Avith hot fomentation, when the complaint seemed doubtful. If the complaint begin Avith a violence of the in- flammatory symptoms proportioned to the injury to be pro- duced afterwards, both to the joint and the system, bleeding Avould first of all be thought of. But, Avhen the surgeon is first called, there is a Ioav irritability, Avith a quick, small pulse, and he is more inclined to apply stimulants to the sur- face, without further reducing the action of the part by leeches ; or supposing that the disease appears in a state so equivocal that the patient thinks it still rheumatic or gouty, a large stimulating plaster may be applied to the hip and thigh. But if the complaint be distinctly marked, the caustic js to be immediately applied. * See what is said on the subject of tumours. 102 DISEASE OF THE KNEE J01NI. CHAPTER VI. DISEASE OF THE KNEE JOINT. Operations are at least proposed to be performed on the knee joint, Avhich make it necessary to take a general revieAv of the diseases of the knee. Why Ave should take this joint in particular after the hip joint, is sufficiently evident. It is the largest joint ; it carries tlie whole a\ eight of the body and limbs; it is Aveak in the structure of the bones, and consequently complicated in its ligaments. The ligaments and tendons about joints are very subject to disease, and here they are exposed^ being only covered by the integuments, whilst in the other larger joints they are protected by large muscles. In White Savelling, an uneasiness and Aveakness in the joint are first observed ; the pain increasing, it is observed to be fixed ; and hoav on each side of the tendon of the patella there is a soft, puffy tumefaction. By some supposed strain, or in consequence of damp, or cold, there is an increase of pain and SAvelling ; in proportion to the increase of pain is the swelling becoming more general. When the pain increases, the constitutional irritation commences, and is mark- ed by an accession of fever in the evening. The SAvelling of the knee in this disease has something peculiar in it; the skin is smooth and clear, the tumour regular and uniform, covering and concealing the natural projections of the heads of the bones. The disease is yet in the ligaments and cellular membrane around the joint, and perhaps not yet in the cartilages of the joint. But now a very peculiar appearance is produc- DISEASE OF THE KNEE JOINT. 103 ed. To save the pressure on the joint the patient allows the toes only to touch the ground, the knee is consequently bent, and the inflammation Avhich surrounds the hamstrings produces a permanent stiffness, the leg and thigh Avaste from inaction, so that altogether the SAvelling of the knee appears more remarkable than it is in fact. The disease proceeding in its course, and the hectic fever being established, the strength and spirits fail; the cartila- ges of the joint are noAv consuming, and about this time the symptoms are aggravated by external inflammation ; the skin sometimes bursts and discharges pus, Avhich has often no connexion Avith the general SAvelling, nor does this discharge diminish the SAvelling, or relieve the pain of the joint in any considerable degree. But matter is now formed around the joint, and the sinuses will sometimes admit the probe to pass in all directions. When the leg is amputated, this is the appearance which is presented on dissection. The cellular membrane around the joint is loaded AA-ith viscid fluid, Avhich, contained in the cellular texture, resembles jelly. The ligaments have lost their natural density and lustre, and fistulous sinuses run be- tAvixt them and the surrounding tendons; within the joint there is lymphatic exudation, in the advanced state of the disease the cartilages are corroded, and lastly, the bone itself suffers by ulceration. The disease varies much in its period. I have seen it rim its course in tAvo months, and I have seen the constitu tion bearing up against it for years, though the disease Avas most distinctly marked, and the suffering ahnost continual. To say merely this is a scrophulous disease, is saying very little. It is a disease falling peculiarly on parts hav- ing little blood circulating in them, and Avhich consequently possess low poAvers of life. It seems first to attack the liga- ments and cellular membrane, and then the cartilages. Often I have known surgeons in consultation on the pro- priety of amputating in a av hite SAvelling of the joint, give their opinion decidedly for amputation, because the bone;' 104 DISEASE OF THE KNEE JOINT. were enlarged. But on dissection, there proved to be no* enlargement. Mr. Russel well remarks in his treatise on tliis subject, that the bones are seldom diseased when they appear to be so, and that the deception proceeds from the effusion that is around the joint. But the bones are actu- ally enlarged sometimes: yet this is no cause for cutting off the limb. There is no reason for determining on an ampu- tation but the declining of the patient's strength to a danger- ous degree. I have looked on the enlargement of the bone with satisfaction, as providing for anchylosis of the joint. If it be denied altogether that the bones are enlarged, then how does it happen that a patient comes to us saying, " It is very odd that his bad leg is longer than the other, although he keeps it thus bent;" is there any other Avay of accounting for this than by supposing that the bones are enlarged ? The enlargement of the bones favours the cure of the disease in this manner: they do not ulcerate on the surface, but become inflamed and spongy in their Avhole sub- stance ; the articulating surface becomes irregular, and ill adapted for motion ; the motion of the joint is lost, the bones unite ; and there being no longer irritation from the incessant motion of the joint, the disease fortunately subsides. In Avhite swelling, the patella is not forced up from its na- tural contact Avith the surfaces of the condyles ; Avhen press- ed it is unyielding, and gives pain. We have to doubt the reality of there being a dropsical SAvelling of the joint, unless the patella yields on pressure, or the fluctuation can be dis- tinctly felt on one side of the tendon of the patella, when Ave strike smartly on the other side. When a patient, perhaps of a Aveakly constitution and pale countenance, is seized writh an attack of pain in the knee, I do not immediately think of applying leeches ; but, on the con- trary, foment, Avrap the limb in flannel, and keep it in perfect rest. If the pain continues, and is fixed, not diffused over the joint, nor lias shifted to any other joint, I dread that Ave are to have a confirmed Avhite swelling. I take blood by four or DISEASE OF THE KNEE JOINT. 105 five leeches: but not with the intention of reducing the in- flammation by this means, but to prevent a great increase of action on the application of blisters to the sides of the knee joint. Repeated blisters I conceive to be absolutely necessary to remove a deep-seated disease, and I have observed the greatest difference in their effect, according as they have been applied, without previously taking a little blood or not. When there has been a tendency to inflammation, and consid- erable power in the part, blisters have increased the general action in the joint, but Avhen the activity of the vessels was previously diminished, they seemed to have substituted the superficial inflammation for the deeper disease. A blister should be applied on one side of the joint, the size of the palm, and as the inflammation subsides, a similar one is to be put on the other side, and thus a considerable action is to be kept up on the surrounding surface. Unless there is strong reason to suppose that there is an active inflammation in the joint, I would not recommend the common cold application of linen wet Avith the solution of cerussa acetata in vinegar and water. If the swelling and general inflammation of a joint have succeeded to a bloAv, then 1 Avould bleed freely with leeches, and apply the cold Avet cloths to it; but if in a constitution not prone to active in- flammation, there comes a deep fixed pain, I would rather order occasional warm stimulating fomentations with flannel or sinapisms to be applied to the joint, and the application of a stimulating plaster, as of gum ammoniac, with vinegar of squills, or the cummin seed plaster. To weakly children Avith diseased joints, there can be no better applications than the latter. An inflammation of the joints (the knee joint for example) which has no mark of the scrophulous action, nor any thing constitutional in its nature, must be treated with a more rigorous intention of diminishing action. Leeches, and after them cold saturine solutions are applied to the joint, and if the pulse and general fever be rising, blood must be taken freely from the arm, the patient must be purged with the VOL.

When high inflammation attacks the knee in consequence of a blow, and is subdued by evacuations and cold applica- tions, yet it will happen That the relief is only temporary, and the inflammation in all its violence will return. We are kept long in suspense by the great tumefaction, and the deep pain, and are unable to say whether the cavity of the joint have at length partaken of the disease. When the violence of the inflammation cannot be subdued, and the relief is par- tial, then suppurations form around the joint, which when very distinct, may be opened ; but I must here give this cau- tion, that we may not be deceived, and take effusions into the bursa?, or into the cellular membrane, for abscesses. The inflammation will sometimes be continued and violent, and yet the joint escape from the capsule, checking the pro- gress of the inflammation from the outward parts into the cavity. When the inflammation has been violent, there will be ad- hesions betAvixt the tendons and their sheaths, and an oblit- eration of the bursae. The consequence is a stiff joint. Where the constitution is uncommonly good, we may ven- ture by friction and motion to restore the joint; but where the case has proved obstinate, and the inflammation has continued long, in a more obscure degree, we ought to try no such experiments as extending -and moving the leg. Where the limb is longer than the other after any disease of the knee, it Avould be quite wrong to make the slightest attempt^ for this circumstance sheAvs us that the bones of the joint are enlarged. If the capulse of the joint should be Avounded, pierced Avith a nail, or opened but in the smallest degree, there is great danger to the joint, and even to life. I have seen a man suffering from such an accident, delirious, with his face flushed, the eye brilliant, the limbs SAvelling in powerful struggles, yet this high inflammation Avas long in coming, the corner of his adze had been struck into the joint, the Avound OF COLLECTIONS IN THE BURSJE. 10; appeared trifling, and there Avas not the slightest pain or discolouration for many days. I have not seen such inflam- mation of the knee fatal, but I can Avell believe that it may be. It is possible to mistake Dropsy of the Knee Joint for White Swelling, yet I should imagine it was easy to discover when there is fluid collected in the joint in any considerable quantity. In the relaxation and dropsy of the knee joint there is no pain ; when Ave press the patella, the swelling is chiefly on the sides of the ligaments of the patella, it is soft and undulating, and putting the hand on one side of the pa- tella, and tapping the other \\ith the fingers, Ave are sensible of the fluctuation. It is a disease of Aveakness. The dropsy that occurs after fever is evidently so, and is removed with the returning strength. Often the swelling conies suddenly, without its being possible to assign a cause, and it has been considered as a consequence of syphilis and scrophula. The first thing we have to think of, the most effectual, and that too Avhich can do the least harm, is to apply a good elastic flannel roller. I have seen sAvellings of the knee Avhich were taken for the most confirmed disease disappear in a night. Stimulating frictions are to be employed Avhen they do not interfere Avith the bandage, and moderate exer- cise is not only allowable, but necessary to the recovery of the joint, and to give vigour to the circulation. From the violent inflammation Avhich I have described, as a consequence of wounding the joint, it will be evident that my opinion must be entirely against opening the knee joint Avhen such collections are formed in it The BcrsjE Avhich are around the joints are sometimes dis- teffded with fluid, Avhile the joint is not affected. The bursa under the ligament of the patella, or the large bursa under the union of the quadriceps femoris to the patella, are sometimes full of fluid; these I Avould be averse from open ing, because the opening will do no good unless there arise inflammation, and inflammation under the ligaments of the patella AArouId quickly pervade the Avhole knee joint 108 LOOf.t CARTILAGES IN iJif. KNEE JOINT. When the large bursa under the deltoid muscle, and the acromion process of the shoulder is enlarged and full of fluid, compression and stimulants failing, it may be opened if it have arisen as a remote consequence of a bruise. No tumours arising from the deep parts of the hip joint should be opened; even the lesser tumours about the ancle joint and Avrist ought not to be touched with the knife or lancet. The loose cartilages or moveable bodies which form with- in the knee joint are Avith difficulty to be accounted for. They are, hoAvever, a cause of great distress and lameness. A fine young man shall be at cricket, in full career, when these bodies escaping from the corners in which they usually lie, and com- ing betwixt the heads of the bones, he will be throAvn down Avith a pain in the knee, extremely violent and at the same time sickening and subduing. Assisted by the experience of the patient, Ave are to endeavour to get the body from be- tAvixt the prominent parts of the bone6; if the body remains long in a situation giving pain, the secretion of the joint is in- creased, and a considerable inflammation will rise. In this state Ave must allow the loose body to rest Avhere it is, and keep the patient from exercise until it shall, by some accident of position, drop into the place of rest. When Ave have got the body extricated from betAvixt the bones, we must endeavour to keep it there by binding the joint, and pressing down the patella, that no exudation may be poured out in any quantity, and that the surfaces of the bones may be kept in contact, so that the body cannot insinu- ate itself betwixt them. I have said that I am averse from opening the knee joint, and I have never seen a case of loose bodies in the joints, where I could recommend it, or Avhere the pain, laments!, and confinement, attending the presence of the body, wer« not outAveighed by the danger which the operation presented. If ever the temptation to operate should present itself to me it must be in this form : the patient shall have been long tormented, the occasional lameness and confinement must in- terfere with his means of living, he must himself prefer thb LOOSE CARTILAGES IN THE KNEE JOINT. 10,9 risk to the incessant pain and helplessness, and the body with- in the knee must be loose, and distinctly felt prominent. The Operation may be thus conducted: The body hav- ing presented in the side of the joint, and upon trial is found to be so far stationary that it bears pressure, and the motion of the skin over it, the assistant is to be employed thus: He must, Avith the fingers of one hand, draAv aside the in- teguments Avhich naturally lie over the body to be cut out, and hold them firmly; Avith the finger of the other hand he must thrust upon the integuments by the side of the body, and into the interstice of the margins of the bones, so that he may prevent the body from moving on that side.# The sur- geon (having his instrument ready to be handed to him) fixes the finger of his left hand on the other side of the body to be cut upon ; then Avith a very sharp scalpel he cuts lightly on the skin until the body starts out or is exposed. As soon as it is exposed the hook is to be introduced behind it, that it may be brought forward. If forceps of a common form be used the body is apt to start from them; they should be armed Avith sharp crooked claws at the point. If the loose body escape, the probability is that Ave shall not be able to bring it to the same spot again, and the danger of the operation will have been incurred Avithout advantage. If the body adhere to the ligaments by a neck, it can be cut aAvay easily, but if it have a broad connexion and require tlie first incision to be enlarged and a dissection made, it is very unfortunate. By all means let the Avound be closed as quickly as possible. I cannot refrain from expressing my wonder that any one should recommend the incision to be left open for the dis- charge of the fluid of the joint. The patient must be kept long perfectly quiet, and the wound must be entirely healed before he be allowed to use his leg. * Some have recommended that the loose body should be moved up- wards on the side of the condyle, towards the connexion of the capsule with the thigh bone. If this can be done, it is certainly better than cutting in the middle of the capsule. But the general rule is to tako that position in wh V.h the body stands roost prominent and secure 110 Or FRACTURED BONUS. CHAPTER VII. OF FRACTURES. DISTINCTIONS RELATIVE TO FRACTURED BONES. The several varieties of fractured bones may be notic- ed under the heads of 1. Simple transverse fracture. 2. Ob- lique fracture. 3. Compound fracture. 4. Complicated fracture. The last of these has the greatest variety of im- portant circumstances connected with it. Simple transverse fracture is that in which the bone is broken directly across, or nearly so. It is the consequence of an injury lateral to the bone; occasioned, for example, by a weight falling on the thigh; or by a fall in which the fore arm strikes against a stone ; or by a stroke on the arm bone. There is in general, comparatively, little injury to the surrounding parts, and no shortening of the limb from the retraction of the muscles. Oblique fracture is a consequence of force applied in the direct line of the shaft of the bone. DIFFERENT KINDS OF FRACTURE. Ill The points of the broken ends of the bone are longer and -harper, and are driven more into the flesh, than in the simple fracture; the fracture is not directly across but ob- lique, and sometimes the bone is riven up. There is, in this fracture, a greater difficulty of setting the ends of the bone in due apposition, and in preserving the length of the limb, for the obliquity of the fracture allows tlie extremities to pass each other. The Compound fracture is Avhere the bone has not only been fractured, but has also pushed through the skin. This in a remarkable manner changes the nature of the case, and the chance of cure is diminished. The Complicated fracture, as I have said, has many varie- ties, in which the difficulties of the case are increased, and the cure becomes more precarious and tedious. One is where the bone is not merely broken across, but shattered or broken in more than one place. Another is a fracture by gun-shot, which has several essential circumstances quite peculiar. Another complicated case is, Avhere the broken bone has been forced against an artery, and the fracture is complicated with aneurism, or there may be both fracture and dislocation, as frequently happens in the ancle joint. A fracture, where the fissure of the bone is continued into the neighbouring joint. 112 TO DISTINCHHSH FRACTURE *R03T DISLOCATION. must be classed under this head. In fracture of the spine too there is more danger from the injury to the spinal marroAv, than from the fracture of the bone; and in fracture of the rib, with injury of the lungs, the importance of the case rests chiefly on the latter circumstance. The danger and all the circumstances of the cases now enumerated being peculiar, they may be ranked under the class of complicated fracture. Fractures of the skull form a subject quite distinct, on ac- count of the peculiarity of symptoms, and the treatment to be followed, the whole case coming under the influence of a very different principle from that Avhich regulates the practice in cases of the fracture of other bones. When, in consequence of a fall, the limb is distorted, and evidently fractured, the greatest precaution should be used in replacing it in its natural position, and the patient ought not to be moved from the place until such temporary support be given to the limb, that he may be carried without pain or farther injury from the motion and twisting of the shattered, ends of the bones. When a surgeon is sent for to an accident of this nature, another surgeon being expected, he ought to wait before he examines the limb, that they may together observe the mo- tions and feeling of the limb without occasioning any unne- cessary pain. But if the accident be recent, and the SAvelling coming on, the surgeon ought not to lose the favourable opportunity for examining the position of the bones and the joints. When the swelling and inflammation have arisen, such examination will often be found impracticable. If a surgeon come to the side of a patient in this situation, or perhaps after the limb has been dressed, he cannot make the due examination, and ought not to hazard an opinion. The bone is ascertained to be fractured by the unnatural position of the limb, the hand or foot being generally tAvisted, or having fallen doAvn; by the harsh grating feeling commu- nicated to the finger, Avhen placed on the injured part, during T,0 DISTINGUISH FRACTURE FROM DISLOCATION. 113 the movement of the limb. In feeling the part, Ave continue to trace some projecting spine (as of the tibia or ulna), the bet- ter to ascertain the displacement of the bones. But this being insufficient fully to inform us of the nature of the accident, Ave must take the Avhole limb in our hands, or make a careful as- sistant do this while we have our hands surrounding the injur- ed part, or, should it be an injury of the chest, Ave place the hand broad on the side, Avhile the patient breathes. In performing this necessary office, I need not say that the bone is insensible in its natural state, and before inflammation has arisen, and that the pain occasioned by the accident is owing to the injury of the soft parts: the pain of the opera- tion is merely that of the repeated injury of the surrounding parts by the ends of the bones; so that every unnecessary motion is to be guarded against. But it is of more import- ance to say that, in the first examination of a limb, Ave ought to be fully satisfied so as to leave no doubt of the nature of the accident, for if Ave cannot ascertain the nature and extent of the injury at first, we shall be less able to do so when the swelling and inflammation have advanced ; and when that SAvelling and pain have subsided, the time for remedying the distortion is past; we have lost an opportunity not to be re- gained. Where great arteries or nerves run close upon the fracture, (as in fracture of the thigh bone a little below its middle), we must be particularly careful hoAv Ave move the bone; for by incautiously tAvisting it, or by the rough carriage of the limb, the artery may be torn upon the sharp ends of the bone. It may in general be said that, in distinguishing fracture from dislocation, there is in fracture less distortion, and less rigidity of the muscles and tendons, Avith greater pliancy in the limbs; and that though there is pain, there is yet free motion when the surgeon moves the limb ; Avhile in dislo- cation there is a checked and interrupted motion. The mere fracture of the bone Avould in no instance require attention to the system, or any. genera! treatment ; but the VOL. TI. 0 114 GENERAL TREAOIENT OF FRACTURE. bruising and laceration of the soft parts which accompany thfc breaking of the bone Tnay, by producing and propagating au action distinct from that Avhich would knit the bones, prevent the formation of the callus or new bone. Either the high and inflammatory state of the general system, or an inflamma- tion tending to suppuration of the part injured, will retard the cure; and therefore all that is necessary, all that Ave can do, is to relieve the system from its high action, to sooth the local inflammation, and as it Avere, to procure time and oppor- tunity for the ends of the bones to take upon them the change necessary for the formation of the callus. When, therefore, we have reduced and adapted to each other, the broken bones, (the manner of doing which I am presently to describe), Ave have to consider the nature and ex- tent of the general or local injury, and comparing it Avith the circumstances and constitution of the patient, to proceed ac- cordingly. If a person in the full vigour of health be thus suddenly confined to a posture, Avith a rising pulse and con- siderable pain, bleeding is indispensable. When there is much SAvelling in the injured limb, it should be placed in a natural and easy position, but not bandaged ; on the con- trary, we bleed with leeches, and by fomentation promote the bleeding and allay the swelling. If, from the violence of the injury, and the shock, and the alarm of the patient, fever and delirium succeed, or restlessness with shaking and spasm of the limb, the fracture should be covered with compresses and soft slight bandage, and pilloAvs rather than splints should be applied around the limb. We must Avait for returning com- posure, and the subsiding of the swelling, before we finally adjust the limb. In this state we must by no means give opiates Avith the intention of quieting the perturbations before very free evacu- ations have been made. If we find restlessness and irritation prolonging the pain and retarding the cure, it most probably proceeds from a neglect of the bowels. By procuring regular motions and by ?»n attention to diet, this irritable state will subside.

During confinement, free air and a change of the bed-chamber, if it can be accomplished, and recreation, is very necessary, for there is a healthy and aatural action to perform. TREATMENT OF A SIMPLE FRACTURE. By the same force Avhich broke the bone, but oftener by the contraction of the muscles, the broken ends of the bone are pushed past each other. Our first object is, by extension of the limb, again to place the extremities of the bone in their natural relation to each other; next we have to take care that the part of the limb which is beloAv the fracture be made to lie in its natural position, that it is not twisted, and not suffer- ed by gravitation or any other cause, to decline from its pro- per direction. Thus, if Ave do not take precautions against it, when the fore arm is fractured, the palm will fall prone and distort the bones : the foot will naturally, by gravitation, fall outAvard, and lie upon its outer edge Avhen the thigh bone or the tibia is broken. When the limb is put into Avhat Ave conceive to be the na- tural position, Ave have to observe Avhether it spontaneously retracts, Avhich it is apt to do if the fracture be oblique. This we must endeavour to counteract. If I can procure it at the time, I use a pledget of soap plaster, which I put upon the limb, especially on the part Avhere the splints are expected to chafe. But oftener along the limb and in those parts where there are hollows, or a flat- ness which will not be uniformly embraced by the splints, 1 lay some layers of lint or old linen soaked in brandy or a solu- tion of crude sal ammoniac in vinegar and water. When avc wish to give unity and firmness to these applications, Ave soak them in gum or in the white of an egg. When stiff unyield- ing splints are to be used, much of the security and ease of , the limb depends upon laying this ground AA-ork. By the 116 GENERAL TREATMENT OF FRACTURE. placing of these aright, all pressure of the bandage or splints may be prevented on the sharp spines, or on the fractured ex- tremities of the bones, and, Avhere the bones are only thinly covered by integuments, or where the skin is tender. Further, by the management of these pieces of linen, and these compresses, the necessity of a bandage under the splinti is avoided; for by this means the splints, coming to press equally over the Avhole limb, (unless on the guarded parts), the limb is uniformly supported by the bandage, Avhich is placed above the splints. I believe that the bandaging of a fractured limb, before the splints are applied, may be of use, when well done ; but it is always attended Avith the danger of being applied too tight at first, or becoming so from the SAvelling of the parts, for in that case it is not merely the undoing of a superficial roller which is required to give ease, but the splints are to be taken off, and the bandage undone, to do which it is necessary to raise the limb from its position. The splints are to be had in the shops, and every young man can make them. But I would recommend pasteboard to be much used, especially in the lesser splints Avhich may be required, Avhile one larger, of wood, or leather and Avood, gives strength to the Avhole. The only disadvantage of the pasteboard, is, that in the event of rising inflammation and tumefaction, Ave may wish to apply wet and cool cloths to the part, by which the splints are softened ; but still if the larg- er splint be firm, it will be a sufficient guard. When there is an evident necessity, in the beginning, for fomenting the limb, it ought to be laid out on the tin splint. It Avill be understood that I apply the bandaging over the splints. I have only to add, that we ought not to use one very long roller, but lesser ones, distinct in their attachments; and that the one last applied should always be the tightest, for if the limb SAvells too much, or there is pain and uneasiness, Ave ought to have it. in our power to ease the Avhole, by undoing the outermost bandage. GENERAL TREATMENT OF FRACTURE. H7 If the first turns of a roller be tight, the Avhole must be undone before Ave can loosen these; but if it be lightly put round at first, and then with increasing tightness, then mere- ly to unpin it, and undo one or tAvo turns, gives relief. In most cases the eighteen tailed bandage is to be preferred to the roller. When Ave bandage a limb for Avhatever cause, Ave must support the loAver part of it by a feAV turns of the roller; else a fulness and kind of strangulation, as it Avere, will take place in the hand or foot. In regard to the position in which the broken member is to be laid, Ave may say in general that the joint is to be re- laxed, or the limb placed in a half-bent position ; there are exceptions to this rule, but Ave shall reserve this part of the subject until Ave come to speak of the particular accidents. In laying a limb Avith a compound fracture while the general principle remains the same, some things must be dif- ferently managed from the simple fracture. We have already remarked that there is a real and import- ant distinction in the simple and compound fracture, arising from the mere breaking of the skin, or the external Avound. Our first care then is, if possible, to reduce the accident to the nature of a simple fracture, by securing the healing of the external wound. But perhaps the bones project and cannot easily be withdraAvn from the wound. This plan will shew that Avhen the end of the broken bone projects, the direct extension of the limb is improper, it forc- es the sides of the bones against each other, and the upper na GENERAL TREATMENT OF FRACTURE. broken portion of the bone into the flesh.—If we Avere to pull this leg in the direction A, then B, would be forced against C, and the sharp point C, forced into the flesh, and the wounded integuments would be girt round the ends of the bones. We must therefore extend the loAver part of the leg in the axis of the loAver end of the bone, in the direc- tion B, D, until the two ends of the bone are no longer thus locked into each other ; then raising the foot into the posi- tion A, the parts are adapted to each other. If there project through the skin a long splinter of the bone, which we foresee cannot Avell be retracted, or perhaps without injury to the surrounding soft parts, then it had better be taken off with the saw.—To saw or break off the projecting point is better than to cut up the integuments. When the bones are replaced, our next object ought to be so to adapt and bring together the integuments, that they may unite by the first intention. They ought to be brought together by a slip of plaster, if they admit of it, and over this a piece of dry lint should be laid on lightly, so as to absorb the first exudation; this may be covered by a piece of cerate; but nothing, oily should touch the wound, where we hope for the scabbing and healing of the broken skin. In other respects the limb is to be managed as a simple fracture, only that in the bandaging Ave should not use a roller, but the eighteen tailed bandage; and in applying it by leaving such tails, as cover the wound, hanging out un- tied, till the rest are bound up, they can at any time be un- pinned and taken off, to expose the Avound for the conve- nience of dressing, without moving the rest of the bandage, or disturbing the limb. But a compound fracture in the common application of the term, may be a bruised and lacerated limb, complicated Avith fracture of the bone; not the effect for example of a shock in falling, which breaks the bone and pushes it through the skin; but of the injury received by a waggon wheel going over the limb, bruising and cutting and laying open the shattered bone. Here, of course, the reduction and po- GENERAL TREATMENT OF FRACTURE. 119 sition of the bone is our least care. The inflammation in a good constitution must rise to a great height; in a bad constitution the natural high action, (a necessary consequence of a previous healthy state of the body in these circumstanc- es), may be converted into bad inflammation, and have a tendency to gangrene*. We have to study the previous state, and Avatch the present symptoms; relieve the high ac- tivity by bleeding and every relaxing means, lower the irri- tation, or correct the habit; and as to the limb, to lay it ea- sy is our only aim, until the high tumefaction and pain shall have subsided ; then suppuration will also have taken place. Good suppuration ensures the subsiding of the inflamma- tory tumour, and of the high tension and irritability. But if after a time, the discharge continues and becomes pro- fuse, there is either a cause of irritation in the Avound Avhich may be removed, or the constitutional poAvers have been al- lowed to go too low. By probing gently, perhaps, a loose piece of bone may be removed, with an immediate change in the complexion of the Avound; or on examination of the parts we may discover a lodgment or sinus, which AArere bet- ter opened. When the pulse indicates rather the quickness and irrita- bility of langour or exhaustion, than of inflammatory fever, by changing the plan of diet, and general remedies, and by supporting the system, we may restore due energy to the bodily powers. When the languor increases, the appetite fails the per- spiration is copious and easily excited, and a purging threat- ens to reduce the patient to a still greater degree of weak- ness ; then bark and Avine, mild nourishing diet, and free air, if possible, are our resources. After this, the patient still sinking, and the integuments losing their tumefaction, and becoming loose and flabby ; and from the unfavourable state cf the boAvels, the food having ceased to be nutritious Avhile * In practice it is of the utmost consequence to ascertain the state of the soft parts—a fracture with contusion, though we must call it a simple fra<- 'ure, is often •worse than a com^cu^d fracturr. 120' GENERAL TREATMENT Of FRACTURE. wine and brandy give but a temporary excitement, Avithout returning vigour, the question of amputation comes to be discussed. If the powers of the constitution be not entirely exhausted, so that there is not vigour to produce the ne- cessary tumefaction, and adhesion of the flaps on the stump, amputation will be safe. There is one point of doctrine on which I believe it neces- sary to say a feAv Avords in these introductory remarks. It regards the nature of callus, and the question concerning the extent of motion which may be allowed to a fractured limb. If this book possess any merit in proceeding directly to that point, the consideration of Avhich most embarrasses the surgeon, it results from my having observed the difficulties Avhich my house pupils experience in fully comprehending their teachers, and from attending to their remarks and their reasoning. It Avas only a few days ago that I heard a very ingenious young man, who lives Avith me, say, that the frac- tured thigh bone should not be set until the end of the third Aveek; and he supported his opinion by the practice of an hospital surgeon of some reputation. A short and energe- tic expression of my conviction of the folly of this dogma Avould not carry the same Aveight with it here as I hope it did Avith my pupil. I shall therefore insist upon it more at length, and discuss also the question of the degree of motion to be alloAved to a limb in fracture, someAvhat largely. I have before me the short notes of three dissections, which, if I mistake not, afford me full ground upon Avhich to reason securely. 1. The first describes the state of the parts immediately af- ter the fracture. The bones have suffered a complicated fracture, being much shattered; they hang together by the surrounding cellular membrane, and the periosteum—they are surrounded Avith coagulated blood. 2. The second refers to a fracture of the thigh bone, if I re- collect, three A\reeks after the fracture occurred. " The bone has been broken across in two places, leaving an intermediate portion. The intermediate portion is immersed in a sub- GENERAL TREATMENT OF FRACTURE. 131 stance, which to the eye is like jelly, but which has a consid- erable degree of toughness. It appears as if the periosteum were continued from the circumference of the bone ; yet this cannot be. There is here a new formed membrane, which in time would have been the periosteum of the new formed bone. This periosteum is remarkably strong and thick, and the toughness which it has in a remarkable degree is possessed also by the callus to a considerable depth. In this mass I disco- ver with my hook or probe many distinct particles of bone." 3. In a preparation of a fractured bone, Avhich had been firmly knit together, and which after being injected had been made in a degree transparent, I observe the old bone white and little porous, but the neAv formed bone Avhich unites the old portions is more vascular, and deprived in a greater pro- portion by the acid of its phosphate of lime. From these facts, Avithout entering upon a physiological view of the subject, I shall endeavour to draw the practi- cal lesson. When the injury is first committed, the cellular membrane around the broken bone is torn ; the lesser vessels are open- ed ; and the blood is unusually effused. At this time any slight motion of the bone does no harm unless it tears up new parts. Presently the blood is absorbed; the injured parts throw out a more regular secretion; the membranes form neAv adhesions to the bones; a tough membraneous sub- stance unites them, and in the apparently confused mass, which surrounds the extremities of the bones, small irregular points of bone are formed. Is not this sufficient to give con- viction that if the limb be rudely moved after the new adhe- sions are formed, these adhesions must be again torn up ? and if these particles of bone be formed, must not the motion of the limb cause them to cut and tear the vessels and mem- branes by Avhich they are surrounded ? so that at last if this motion be allowed to any extent, the disposition to the forma- tion of bone is destroyed, and the process baflled as it Avcre, in its design, stops short of the true effect, and the bones are united not by bone but by a tough ligamentous substance, VOX. u. i? 122 GENERAL TREATMENT OF FRACTURE. and the extremities of the broken bone are rounded off, so that an artificial joint is formed. It is surely no erroneous conclusion to draw, that motion, to a certain extent, Avill de- stroy the disposition in the action to unite the bones by bone; and that in a lesser degree it retards the cure, and makes the confinement longer, increasing the chances of failure. On the other hand, no argument -will ever be discovered against giv- ing absolute rest to the limb. But Ave must not be so blinded as to carry the argument too far. If, on examining a limb, Ave find that it is distorted or re- tracted, Ave place it again in its proper position, and endeavour more perfectly to secure it, because by this twisting or exten* sion we do not, as by a perpetual teasing interference Avith the process going forAvard, destroy the usual disposition. Here the neAV adhesions may be broken, and they -will readily unite again, and the cure go on. To say, however, that because Ave can thus interfere with a broken limb, Avithout essentially interrupting the cure, it is time enough to set the limb in its position after four weeks have elapsed, were to carry the doctrine to a dangerous as Avell as a ridiculous excess; for at such a distance of time from the accident, the connexions must be strong, and the violence necessary to replace the limb in its natural situation proportionally great. It is but at best bringing matters to their original state, and of course the previous time is lost; the confinement being in this way much increased. We can as- cribe such extravagant practice as this, only on the one hand to ingenious argument pushed rather too far for common readers, and on the other to stupidity in taking the illustra- tion of a doctrine for the enunciation of a principle. A frac- tured bone will feel quite loose towards the end of the third Aveek, and in three or four days more it will be firm. This, I suppose, is the origin of the opinion, but the fact is insuifi dent to establish the rule of practice GENERAL TREATMENT OF FRACTURE. lO-' 1 ^V,v> OF THE MEANS PROPOSED FOR EXCITING THE OSSIFIC ACTION WHEN A JOINT HAS BEEN FORMED IN CONSEQUENCE OF THE MISMANAGEMENT OF FRACTURE. , When, in consequence of using the limb too freely a joint has been formed, instead of the bone uniting, it has been pro- posed, to cut doAA*n through the flesh, and to cut off the cal- lous extremities of the bones. I do not recollect that this has ever been done Avith success, but I knoAv that it has been done with continued pain, during the operation, almost to death, and with no good effect. The thigh has been cut so that the bone has been exposed, but lying deep in the flesh ; the disentanglement of the end of the bone has been found most difficult, painful, and tedious; the saAv moving in these deep parts requires a large Avound and moves with difficulty, and in one case, long before one extremity of the bone Avas cut off, the patient Avas pale and feeble, and incessantly vomiting from pain and irritation. I believe hours have been spent in the attempt, and Avhat has been the result ? an extensive open wound, the ends of the bone consequently exposed, and these ends injured by the Avorking of the saAv. A disposition in short is left upon the part the very reverse of the quiet ossific action. There follows inflammation and suppuration, (ever at variance, Avith healthy ossification), the inflammation has subsided, and aa hen the parts may be ex- pected to granulate and take the disposition to unite by bone —that disposition has been already destroyed by the a iolence of the inflammation, the time for their union is past, and the bones remain loose as before. In one case I thought myself, by observations made on animals, authorized to propose that a long and sharp instru- ment should be pushed obliquely doAvn upon the bone, so as to Avork upon and penetrate the extremities of the bones. By this means I imagined the wound made by the transit of the instrument Avould immediately heal, and yet the extrem- ities of the bone be fo excited a? to resemble the state of 124 FRACTURE OF THE CLAVICLE, simple fracture more than can possibly happen after cutting down upon and sawing their ends. But perhaps the patient reasoned better than his surgeon since he would not submit I still insist on the necessity of absolute rest after 6uch opera- tion for re-imion of bone. FRACTURE OF THE CLAVICLE. The clavicle may be broken by a Woav directly upon it; but it is most commonly broken in consequence of the per- son pitching on his shoulder as in falling from horseback. The fracture of this bone is ascertained by remarking that the shoulder is fallen doAvn towards the breast, and, on feeling along the bone, the crepitation of the broken ends is perceived, or the broken ends are found to have passed each other and one of them to ride upon the other. The motion Avhich the patient makes Avith the greatest difficulty, is to touch the shoulder of the opposite side, or to raise his hand to his forehead: for this motion tAvists the broken clavicle, and forces the broken ends into the cellular membrane. The indication is to keep the shoulder from falling for- Avard and the arm from dragging. If the patient be drunk, compresses are to be put over the tendons of the pectoralis major, and a figure of 8 bandage to be so applied as to draw the shoulders powerfully back, that no struggling or thoughtless motion be allowed, Avhich might tear the parts against the sharp bones. When the bone is to be set, an assistant draws back tlie shoulder, Avhile the surgeon examines the position of the bones; and when the broken ends have been draAvn into their natural relation, some flat compresses of linen are to be placed as directed before the arm-pits, that the bandage may not cut the skin. The double-headed roller is now to be applied: putting the middle of the roller across the back, the surgeon brings two turns under the arm-pits,and over the shoulder, then, by crossing the roller on the back and FRACTURE OF THE SCAPULA. 125 again bringing the turns to bear on the shoulders, they are retained braced back: after a few yards of the roller are thus applied, the shoulders are fixed, and the arm cannot fell forward, Noav a soft cushion, or pad of lint, is to be placed in the axilla, and the turns of the roller being secured, the end is to be brought down upon the back and outside of the arm, so as to bear on the elbow and brace it to the side. This in consequence of the compress being in the axilla, still further removes the shoulder from the sternum, and keeps the brok- en ends of the bones from passing each other. If the bones come easily into their place, then the pad need not be applied in the axilla until after a time the roller is somewhat loosened by stretching, or it be necessary to make some substitute for the severe bracing of the roller. When the shoulder is braced back, Ave must notice if the bones be on the exact level. And, at all events, it is necessa- ry to sling the arm, to prevent the falling down of the outer portion of the clavicle; for this purpose the fore arm is put in a large handkerchief, the ends of which are to be tied round the neck. No kind of compress must be allowed on the ends of the broken bones, for they are ineffectual as to keeping the bones in their place, and only press the tender siin against the sharp bone. If it be found that the patient is often feel- ing and pressing the bone, it may be well to put a piece of leather spread with adhesive plaster, over the clavicle, sim- ply to keep off his fingers. FRACTURE OF THE ACROMION PROCESS OF THE SCAPULA. When the shoulder is black and blue, and it is found that the patient has pitched on it, but yet the clavicle is not brok- en ; and when there is crepitation on pressing the prominent part, and some disfiguration of the shoulder joint, we shall find that the acromion scapula; is broken. But the fracture of the acromion is even more apt to be a consequence of a 126 FRACTURE OF THE SCAPULA. weight falling on the shoulder, than of a person pitching with the shoulder to the ground. If the acromion process be broken, we see on taking hold of the arm of that side and either pulling it doAvn, or letting it drop Avith its OAvn weight, an evident sinking of the top of the shoulder; or on applying one hand to the shoulder, Avhile Avith the other Ave moArc the arm, a crepitation is felt. On pushing up the arm bone, there is pain, and Ave see the point of the acromion unnaturally elevated. In fracture of the acromion scapulas (which, by the bye, is not a frequent accident, oAving to the Aveakness of the clavicle,) Ave raise the arm, and relax the deltoid muscle, and examine and replace the pieces of the bone. Then the arm being al- lowed to fall gently doAvn, the fore arm is to be suspended in a handkerchief, so that the head of the humerus may be made to push up the extremity of the broken acromion, and preserve it in its place. As this injury proceeds from a di- rect blow on the part, the pain and tumefaction of the integu- ments of the shoulder Avill be great, and no bandage can be applied with advantage until the SAvelling has subsided: then the spica bandage may be put on. The spica band- age is a form of applying the double-headed roller. The middle of the roller is put under the arm-pit of the oppo- site side; then the ends are brought up and crossed on the top of the wounded shoulder; then they are crossed under the arm-pit of the same side; they are then carri- ed across the back and breast, and the heads of the roller are again crossed under the arm-pit of the opposite side, and so are carried up on the injured shoulder again—and this is repeated until the shoulder and the broken bones are cover- ed with a firm lacing of the bandage. It may be necessary to relax the deltoid muscle, in order to keep the bone in its place. If the acromion be alloAved to unite Avith its point depressed, it will check the motion of ihf, arm bone. FRACTURE OF THE SCAPULA. 127 OF FRACTURE OF THE BODY OF THE SCAPULA. Of the other parts of the scapula, the inferior angle is ex- posed to be fractured next in degree of frequency to the acromion process. It may be broken by falls or bloAvs. I have been consulted by a peison complaining of a great pain in the loAver part of the shoulder blade from a fall, and yet I have found that this part never touched the ground or re- ceived a direct injury; but had been injured by the sudden action of the latissimus dorsi on the angle of the scapula in the sudden twist of the trunk, and in the exertion to save himself from falling. There is sometimes a dislocation of the tendon of the latis- simus dorsi, in consequence of the angle of the scapula get- ting over the tendon, so that the arm cannot be carried for- Avard or lifted. When there is fracture of the loAver part of the scapula, avc have to press the fingers around the lower angle of the scapula, as if to fix it; then, raising the patient's arm, so as to roll the body of the scapula, if the loAver angle be broken off, it does not folloAv the motion of the body of the bone. It is not practicable to bring the lower piece to ansvver to the body of the bone; but by managing the position of the arm, the body of the scapula may be brought to meet the lower piece, and to come into accurate contact Avith it. To. effect this, Ave carry the patient's elbow forward on the chest, and when Ave feel that the parts of the scapula correspond, Ave place the palm of his hand on the opposite pap and bind the arm to the chest: for this purpose the fore arm is to be slung in a handkerchief, and pads or compresses put betwixt the arm and scapula; and then a broad roller is applied round the body, including both the chest and the arm of the injured side„ 128 FRACTURE OF THE HVMERVS. FRACTURE OF THE HUMERUS. This is the simplest of all fractures. It requires only two pasteboard splints, one on the inside and the other on the outside of the arm. The fore arm should be hung by a handkerchief, in such a manner that the wrist may be more supported than the elbow, so that the weight of the arm, counteracting the action of the muscles, may serve to keep the ends of the bone in their proper place. I have seen the imperfect joint formed in the arm bone oftener than in any other. We must endeavour, in this case, by rude motion, to excite inflammation in the ends of the bones, after which the steady binding of the arm Avith splints, Avill certainly succeed in uniting the bones. The humerus may be broken very near its head; the neck of the humerus cannot be broken, because there is, in fact, no neck; but, in a young person, the head may be broken off at the joining of the apophysis. This has been the conse- quence of the recoil of a musquet, AAhen a lad, in firing his piece, has not rested it on the shoulder, but on the arm bone. Fracture of the humerus, near the head of the bone, is un favourable, because of the strength of the muscle which sur- round it: the pectoralis major and latissimus dorsi, the del- toides and teres major, act on the lower piece of the bone, and make an essential difference in the case from that of the simple fracture of the middle part of the bone. The force of these muscles should be counteracted by the weight of the arm, slinging it by the wrist only and not supporting the elboAv. We must in this case too, be careful to adapt a splint to the inside of the arm, with such a pad as may fill the axilla without too much encroaching on the head of the humerus, or in the least pushing it from its place; then a piece of pasteboard is to be moulded to the shoulder, and the spica bandage applied and continued in the form of a roller on the arm. FRACTURE OF THE OLECRANON. 129 OF THE FRACTURE OF THE OLECRANON. The olecranon may be fractured Avhen a person in running falls, and strikes the elboAV on the ground. No marks are required to distinguish when the prominent process of the ulna at the elboAV is broken off. It Avill, how- ever, be observed that this makes quite a peculiar case from the circumstance of the strong triceps muscle being inserted into the process of the bone which is broken off. The bent, or relaxed position of the limb, which is the position of ease in most fractures, would here have the worst effect, by mak- ing the body of the ulna recede from the process Avhich is broken off and attached to the tendon of the triceps. Let the fore arm be extended; yet not to the utmost stretch. Then the triceps is to be pressed, Avith a vieAV to relax it, and the olecranon brought doAvn to its place. Dossils of lint are then placed on the sides and above the olecranon ; and over these a roller is put on the arm and fore arm. A splint must then be applied on the fore part of the elboAV joint with lint beneath it, to fill up the inequality of the joint, so that the fore arm may be prevented from extending fully to the straight line ; and, at the same time, prevented from being bent at all. These cautions are to be attended to ; because, in the first place, by extending the arm too much, the olecranon, which has been broken off is pushed from its notch in the lower head of the humerus; and consequently it does not perfectly and correctly unite with the body of the ulna. In the na A'OL. it. s 130 FRACTURE OF THE RADIUS. tural state of the joint, the olecranon checks into the holloAv of the humerus so as to stop the motion at its due limit, but that check being iioav done aAvay, the fore arm may be bent back unnaturally, and the ligaments of the joint strained. In the second place, it must be observed, that if the joint be not enough extended AAhen the bone is set, callus or neAv bone Avill be formed betAvixt the ulna and the process which has been broken off, and a land of anchylosis is the conse- quence ; for the olecranon process projecting noAv too far, will strike into the IioIIoav of the humerus, before the fore arm can be fully extended. See plan plate IV. fig. 4. A, is the humerus; B, the ulna; C, the olecranon, broken off; D, the holloAv of the humerus, into which the olecranon should sink, AAhen the arm is fully extended. But it is evident, that if the dotted line betAvixt B, and C, be filled with hcav bone, there must be a stiffness in the joint, of the nature of anchylosis. FRACTURE OF THE RADIUS. • The fracture of the radius may be the consequence of a direct bloAV on the fore arm ; or of a person's falling and en- deavouring to save himself, by extending the hand; for the, carpus being articulated with the radius, the whole shock and weight of the body falls on this bone. The nature of the injury will be ascertained by the usual symptoms of fracture: and, besides, it will be found that the hand falls prone, with much pain, because the Aveight of the hand bears so that the carpal bones and loAver head of the radius turn on the small head of the ulna, while the upper part of the radius, not folloAving the loAver in its rotation, the broken ends are separated, and the surrounding parts injured. The patient therefore comes to you, holding the palm of the injured arm with his other hand, to prevent the motion either of pronation or supination, but especially the former. The effect of pronation will be understood by looking to the annexed sketch of the bones of the fore arm. A, is the upper FRACTURE OF THE RADIUS. 131 broken part of the radius; D, the lower portion : now by the falling of the palm C, prone, the portion D, turning in the circle A, B, is separated from the upper portion of the bone, and the tearing of the cellular substance, or the bearing of the sharp bone against the parts, is the cause of the pain. It will be manifest, at the same time, that, if the bone be alloAved to remain in this position, a great, irregular callus must be formed betAvixt the ends of the bones; and that, when they are thus fixed together, the hand will be no longer capable of supination. In setting the radius Avhen fractured, Ave have to apply the splints thus: one along the inside and the other on the out- side of the fore arm : The one on the inside should be long enough to reach to the palm, that it may prevent pronation. It is important to observe that if a splint be laid along the ulnar edge of the fore arm, and be made to reach to the palm; or if the arm and hand be laid carelessly in a sling, the following bad consequence results : the ulnar edge of the palm is pressed up, the head of the radius receives that pres- sure, and the broken ends of the bone are pressed doAvn upon the ulna, as is expressed in this sketch. A, is a splint, on which the arm and hand rest. Noav it is evident that, when the ulnar edge of the hand is thus raised, i 132 iRACTURL OF THE THIGH BONE. the radius can no longer keep its natural shape, as indicated by the dotted outline, C; but that, on the contrary, the sharp and broken part of the bone will be pressed near the ulna, as at B. The consequence of this is, some distortion of the wrist, and an impediment in the rotation of the radius and hand. FRACTURE OF THE BONES OF THE HAND AND FINGERS. The bones of the carpus and metacarpus are seldom brok- en, Avithout being accompanied by a bursting, or laceration of the integuments. The hand is caught in machinery, or injur- ed by the bursting of fire arms—the fracture of the bones then is the least of the evil. As to the setting of the bones, that is an easy matter : to preserve them in their natural situation, the palm of the hand is laid over a cushion or pad, accurate- ly adapted to the hollow of the palm and fingers, and then a roller is to be brought down from the fore arm, over the hand and Avrist, including the pad. When the bones of the fingers are broken, they are to be ' neatly set, Avith pieces of paste-board, moistened and soft; over Avhich a small roller is applied, and to secure the posi- tion of the fingers, if several have been shattered, they may be laid over a small cushion, so as to embrace it. OF THE FRACTURE OF THE THICH BONE. It is evident, on the first consideration of the subject, that, in the fracture of the thigh bone, these circumstances must make a peculiar case : First, The great strength of the bone which implies that there must be great violence and injury done to the limb, at the same time that there is fracture. Secondly, The magnitude of the thigh, and the great proportion Avhich the injured part bears to the whole body should lead us to infer that the injury to the system and the effect on the constitution, will be, in a good measure, propor- FRACTURE OF THE THIGH BONE. 133 tioned to the size of the member Avhich is injured and the vio- lence it has suffered. The Third consideration is, perhaps, the most important one—it relates to the great mass of flesh by AAhich the bone is surrounded. For this great mass of muscle being in unceasing action, the loAver portion of the bone, on Avhich it operates, is drawn toAvards the body, so as to make the broken extremi- ties of the bone ride over each other; which, in the end, often occasion a short and lame thigh for life. Lastly, AA'e must take into account the position of the thigh bone: for, as it stands nearly perpendicularly under the weight of the body, and is broken most commonly by a shock perpendicular to the pillar of the bone, it must be liable to be rent and fractured obliquely. There are very important distinctions to be made in rela- tion to fracture of the thigh bone, from the circumstance of the place and direction of the fracture. FRACTURE OF THE SHAFT OR CYLINDRICAL PART OF THE BONE. When the cylindrical part of the thigh bone is broken, Ave should consider well the place and degree of obliquity of the fracture, before we speak of the event. The higher the bone is fractured, the greater probability is there that the limb may be shortened during the cure. The reason is that the nearer to the upper end of the bone the fracture is, the great- er is the number of muscles inserted into the loAver portion, and the greater the retracting force. But if the fracture should be at the Ioavct head of the bone, and also oblique, (as it is apt to be in that case), then is there danger of the bone uniting Avith an oblique position of the condyles, pro- ducing distortion and Aveakness of the knee-joint. In the treatment of the fractured thigh bone, Ave have ma- ny things recommended, and a variety of apparatus advised, because, in truth, every surgeon has experienced difficulty and disappointment jn managing it. What I have now to 134 CRACTURE OF THE THIGH BONE. offer will, I hope, be found simple, and, in proportion to its simplicity, effectual, for securing the limb in the best position. FIG. l. It Avill be necessary for the first night to secure the lhnb with the common splint and bandage and lay it out on a pil- low. In an hour this frame may be constructed: tAvo boards, A, B, Fig. 1, of ten or eleven inches in breadth and of a length equal to the distance of the heel from the back of the knee-joint, are to be united at an angle answering to an easy and relaxed flexion of the limb, and secured by a horizontal board C. Near the edge of the inclined boards, holes are to be made and pegs of wood fitted to them, D, D. Cushions, like Figs. 2 and 3, are then laid on this frame, when it is ready to receive the limb. The limb.is to be laid over the cushions or mattresses thus supported on their frame. The bone is noAv to be accurately set, (if it has not been already done), by the assistant taking the knee and gently extending it, while the surgeon puts his FRACTURE OP THE THIGH BOffE. 135 hand wide over the thigh and the fractured part, that he may feel the crepitation and the motion which the broken ex- tremities of the bone suffer. Now one long splint is to be laid on the outside of the thigh, reaching from the hip to the side of the knee, another upon the inside of the thigh and over these the eighteen-tailed bandage is to be applied. It is now to be observed hoAv far the thigh ansAvers to the inclined plane, A; for it will be understood, that the thigh and body, in some degree, now hang upon the angle of union of the tAvo boards, and that if this board, A, be much longer than the thigh, the muscles of the thigh will be strained. If, on the contrary, it be shorter the muscles of the thigh will act, and the broken ends of the thigh bone may ride over each other, notAvithstanding the lateral splints and the bandage. To ease the muscles of the thigh, Ave must raise the hip, by placing a thin cushion under it at F: To stretch it, we must take the cloths from under the hip, or make the pad larger under the knee joint at E. To support the foot from rolling, the edges of the pilloAvs or mattresses are folded up and fixed by the pegs so as to give a lateral support to the Avhole limb from the hip to the ancle. If the thigh has been much bruised and be now savoui, perhaps it will be better simply to lay it out on this frame without splints, for it will be soft, and be equally supported, and moderately stretched. What is the most frequent kind of defect in the limb after fracture of the thigh bone ? There can be no doubt that it is shortening of the thigh, together with a tAvist of the limb, which lames the patient by depriving him of the strength from the muscles of the leg, and takes at the same time the length of the foot from the step of that leg. We have now only to consider the latter of these effects of inattention ; hav* ing, as we hope, done all that can be done, by the substitu- tion of a simple contrivance, and by making the weight of the body the counterpoise to the strength of the muscles, to pre- vent the retraction of the limb, and consequently the perma- nent shortening of it. 136 FRACTURE OF THE THIGH BONE. When the limb is merely laid on the outside, and gently bent, as directed by Mr. Pott, and secured by splints and bandages, the body and limbs of the patient lie well, for some little time; the thigh rests on its outside, and the body is inclined the same way: but, by and bye, the patient turns directly on his back, Avhile the leg remains lying with the outside of the foot flat to the bed! Or, again, if the limb has been set Avith the patient lying on his back, and the heel of the broken limb to the bed, the Aveight of the foot in a short time tAvists the leg, so that at last it lies flat on the fibu- la, while the patient continues on his back. This could not take place Avas the thigh bone entire; but noAv the loAver piece of the thigh rolls outwardly, while the upper part re- mains in its place. The bones thus twisted, unite, and, Avhen the patient rises from bed, Ave find that he points the toe too much out in walking, that he carries the side of his foot for- Avard, and has consequently lost the use of the elastic arch of the foot. This sketch will illustrate my meaning. FIG. l. In Fig. 1,1 have given a sketch of the limb, as I have seen it lying—the knee bent, the side of the foot flat on the bed, the leg shorter; (though this is not easily ascertained, from / FRACTURE OF THE THIGH BONE. 137 the different aspects of the limbs), Avhile the patient lies flat on his back. Fig. 2. shows Avhat has taken place—that the broken ends of the bone have shot past each other, by the retraction of the muscles, AAdiile the lower part of it is tAvisted outward, by the falling of the foot on the outer ancle, there being no impediment to this motion from the trochanters and the hip joint as when entire. FRACTURE OF THE EXTERNAL CONDYLE OF THE THICH BOND. When we turn our attention to the natural position of the thigh bone, or when we place the condyles of the bone on the table, we find that the shaft, or cylindrical part of the bone, stands obliquely. So it happens that, in a person who falls on his feet, the weight of the body operates oblique- ly, and the external condyle receives the shock. In this way, there is sometimes an oblique fracture of the lower head of the thigh bone, and the external condyle is broken off. The utmost care is required to prevent the inflamma- tion rising in the first instance, and to provide against obli- quity in the joint. VOD. II. 136 TAaCILRL Ul iJIE 1H1U11 IJONS'. 01 FRACTURE OF JRE. NECK OF THE TniGH BONE. This is a sketch of the bones of the person mentioned in flic text. The right thigh bone is natural, the left one much .shortened by the fracture of the neck. A, the os Innomina- tum ; B, the shaft of tlie thigh bone ; C, the neck of the bone fractured; D, the trochanter major broken off. The compa- rative elevation of this point above the level of the head of the bone, will mark the reason of the shortening of the limb. The pieces of bone were united by a ligamentous substance, not by bone. When we hold the thigh bone before us, and consider the position of the great shaft of the bone, and the obliquity of ERACTURE OF THE THIGH BUNI-. l'V-J the neck, standing off at an angle to the shaft or pillar of the bone; a\ hen Ave consider the strength of the shaft, or cy- lindrical part of the bone, that it stands almost directly un- der the weight of the body, and that the neck of the boneT on the contrary, is smaller and Aveaker, as well as oblique,— Ave see Avhy, in all shocks from the descent of the body up- on the thigh bone, the neck is the most apt to be broken across. The neck of the thigh bone then is broken Avhen the Aveight of the trunk falls upon it; as when a person falls from a height upon his leg", or Avhen thinking that he has come to the landing of a stair, he steps fonvard and falls doAvn tAvo or three steps, with a shock which the neck of the thigh bone cannot bear. A direct bloAv on the joint injures it, but there is no fracture: a twist of the limb dislocates or injures the apparatus of the joint, but there is no frac- ture. It is only the perpendicular impulse that can frac- ture the neck of the thigh bone*. I have dissected the joint some months after the fracture of the neck of the thigh bone, and have found the bones still loose. There was at least only a very imperfect union betwixt them, by a strong and irregular ligamentous mat- ter. I mention this not as a curiosity, but in confirmation of a general opinion, that the neck of the thigh bone will not unite, not readily, in the usual Avay by bone. It is of importance to notice the motion of the hip joint on almost every occasion; in the natural state of the parts, indeed, Ave are aAvare of every motion to Avhich it is liable ; but Avhen the sensibility of the joint is increased by disease or injury, we discover, that scarcely a muscle of the limb moves without moving the thigh bone in the acetabulum: and that the patient does not move his trunk in the slight est degree, but the pain of the joint is excited by the motion of the joint. * Although at tins time, when I am correcting the sheet, I am made sensible that a man may fall on the trochanter, and break the neck f«i' the thighbone; yet I am convinced it is so Uttle likcty to happen, ih.r I venture to keep the text as it stands. 140 TRACTURE OF THE THIGH BDNR. This perpetual motion of the head of the thigh bone, is a principal cause why, being broken, it does not unite. Certainly too, there is something unfavourable in the cir- cumstance of the neck of the bone being surrounded by the secreting and lubricating capsule of the joint, not by the cellular membrane, and vascular muscles, which embrace the broken ends of the bone in other fractures. The broken head and neck of the thigh bone, must be deprived of that due degree of inflammatory action of the surrounding parts Avhich is necessary to sustain and consolidate it. But hav- ing seen the fracture of the neck of the bone, with a break- ing up of the whole trochanter major, and part of the shaft of the bone, while yet there was no union by callus; I can- not attribute the defect of ossification entirely to this cir- cumstance of the difference in the nature of the surrounding substance. The great strength of the muscles surrounding the joint, sufficiently explains that most untoward circumstance, the shortening of the limb, in fracture of the neck of the bone. The Avhole strength of the muscles of the hip, of the psoae muscles, and of the muscles of the thigh, is operating inces- santly in the retraction of the cylindrical part of the bone. To counteract this dragging of the muscles, I knoAv nothing more effectual than laying the limb on the frame Avhich I have already described, I do not imagine that any splints about the thigh or joint, or any kind of bandaging, will be more effectual to retain the limb in its natural position. It is particularly necessary to point out the distinctions betwixt this fracture and the dislocation of the head of the thigh bone. 1. In the first place the surgeon has to attend to the cre- pitation, and for this purpose he puts his hand on the joint, while the limb is moved. But it must be recollected, that the effect of mere inflammation in the joint is to change the secretion of the sinovia so much, that the cartilages move Avith less facility, and produce a jarring sensation, Avhich may be mistaken for crepitation. FRACTURE OF THE THIGH BONE. 141 2. We next attend to the ease with which the limb is stretched. By a majority of consultants, I Avas induced, contrary to my own opinion, to put the apparatus on an old woman, and to endeavour to reduce Avhat Avas supposed a dislocated hip; but placing my hand on the trochanter ma- jor, and pressing a finger of the same hand on the promi- nence of the ilium, I knew decidedly at the first motion of the assistants to pull the limb, that it was no fracture, from the ease Avith which the trochanter moAred, and from the in- crease of the space betAvixt the ilium and the trochanter. 3. In dislocation, the limb is locked as it Avere; but in fracture, it is easily moved, in as far as regards the surgeon, though Avith pain to the patient. And Avhen the limb is moved in fracture, it is Avith a certain degree of elasticity; but in dislocation, by starts, and unequally. 4. When avc make an assistant take hold of the knee and ancle, and bending the,knee joint make the rotatory motion of the thigh bone by using the leg as a lever, we may ob- serve the folloAving distinctions betAvixt fracture and disloca- tion :—When the heel is moved out, the head of the thigh bone checks against the back of the ilium in dislocation; Avhereas in fracture it has no such impediment. Again, when we make the assistant roll the thigh, while Ave keep the fingers on the trochanter major, Ave feel it, in dislocation, making a movement describing a part of a large circle ; but in fracture, it moves on the centre of the cylindrical part of the thigh bone, to Avhich it is nearly parallel, and conse- quently does not escape from under the finger. See further under the head of Dislocation of the Tliigh Bone. As I have caid, I conceive that the frame Avhich I have re- commended, in the fractured thigh bone, will do all that it is possible to perform in the present case; it will retain the thigh bone, and the great trochanter, in their natural place and relation to the neck of the bone. But lest my reader should object to this, and think that it is better to assist the on' ration of this frame work by bandaging and splints, or 112 tRACi-UULD PAXELLA. Avould rather trust to the general experience of the profits- sion, than to my suggestion, he may take the following me- thod :— You extend the limb until by marking the relation of the trochanter major to the ilium, you find you have brought the bones into their due relation to each other. You then lay compresses above and on the sides of the trochanter; then a roller is put round the pelvis and thigh, so as to keep these compresses and the bone firm. (So far it may be well to do before laying the limb out on the inclined planes—I object to what follows, as inefficient). A long splint of wood is noAv to be put along the Avhole thigh, fixed at the upper part by hav- ing the end pushed into the folds of a bandage or belt, which goes round the pelvis ; while to the loAver part are attached bandages, which go round the knee and ancle, and Avhich may be drawn so as to stretch the limb. OF THE FRACTURED PATELLA. The fracture of the patella, or knee pan, happens in conse- quence of a sudden and very strong action of the four mus- cles Avhich are inserted into it while the knee is in that degree of flexion that the patella is raised upon the convex surface of the loAver head of the femur. Sometimes the patient ob- serves that the crack of the fractured bone Avas before he fell to the ground; while, for the most part, deceived in the cir- cumstances, he supposes that in striking the ground, the knee pan has been fractured. It must, at first view, appear strange, that the patella can be broken by the mere force of the muscles! but tAvo things are to be considered, the great massiness and strength of the muscles Avhich operate on it, and the position of the patella. The muscles Avhich operate on the patella, are the rectus, the vastus externus and internus, and the crureus. These which may be called a quadriceps muscle, raise the whole weight of the body, and are poAverful in their ordinary action. But when a man slips his foot, and I may say the whole mus- FRACTURED PATELLA. 143 cular frame is brought into sudden and almost spasmodic ac- tion, the power of those muscles is inconceivably great. Again, the patella cannot be broken Avhen the muscles pull directly in the line of the bone; that is, when the limb is straight; nor yet Avhen the knee is so bent that the patella lodges betwixt the bones, and is supported by the condyles. But when the knee is moderately bent, and the patella is raised on the convexity of the loAver head of the thigh bone, the muscles act at an angle with the ligament of the patella, and then the patella is broken across. The patient falls to the ground, and the surgeon finds that instead of the usual prominence of the knee, the joint is flat, and he feels the great- er portion of the patella drawn upAvard on the thigh, while the other part is still attached to the ligament, and the two condyles of the thigh bone, are prominent. Treatment.—Let the surgeon avoid all motion in the limb, or at least bending of the knee joint, else there will be fur- ther danger of laceration. If the patient is to be carried home, in order to be quite safe, he has only to be carried sit- ting upright in a chair, with his leg extended. There is no occasion for a bandage to secure the upper portion of the pa- tella, from being draAvn further up on the thigh. When the patient is laid in bed, we have to bring the fractured portions together: first, by position ; secondly, by bandage. It will be manifest, that the leg is to be laid (in opposition to the general rule) extended ; so that the lower portion of the patella may be raised on the fore part of the joint. The body must be brought forward in the sitting pos- ture, that the point of origin of the rectus from the pelvis, may incline toAvards the knee, and relax the quadriceps mus- cle. Or instead of the patient sitting in an uneasy posture, he may lie on either side, only having the hip joint bent, and the leg extended. When the extensor muscles of the leg, which are inserted into the patella, are thus to the utmost degree relaxed, the pieces of the patella will have come into their natural posi f?on. A bandage must now be applied to guard them against 144 t'RACTURED BATELLA. the accident of an unwary movement, producing action in the muscles of the thigh. A long double neckcloth is tAvisted together, then laid over the knee above the upper portion of the patella; it hangs doAvn on either side; take hold of the hanging parts of the cloth, and with the fore finger of the left hand, hook that which is held by the right, and Avith the fore finger of the right hand hook the cloth where it is held by the left, so as to bring them across under the knee: then bring the ends of the cloth over the lower part of the joint, and below the inferior portion of the patella, and pass them through their respective nooses, formed as described by the fore fingers, draw the Avhole tight, and then approximate the two circu- lar turns of the bandage, which are above and below the knee pan, by finally passing the ends through the upper cir- cular, and fixing them there. We have noAv to inquire why there is so remarkable a lameness after the fracture of the patella, and why the patel- la of the other side is so apt to be fractured in a person Avho has once met with the accident. The second accident folloAvs naturally from the lameness Consequent on the first; and this lameness, which is so fre- quent a consequence of the fractured patella, proceeds from two circumstances. 1. The fractured pieces are not brought into accurate correspondence; but OAving to the imperfect relaxation of the quadriceps muscle, the upper portion is kept too high to be in contact with the lower, and instead of bone uniting the two parts of the patella, there is a long intermedi- ate ligament, (such as I have represented in the annexed plate). One consequence of this is, that the muscles being alloAved to remain contracted, they lose their power of giving a perpetual tension and support to the limb, and also of ac- commodating themselves readily, and with sufficient strength to the necessary motions. 2. The patella, in its natural posi- tion on the top of the knee, being somewhat removed from the centre of the joint, bestows a power on the muscles, by ex- tending the lever on which they act; but when, instead of FRACTURED PATELLA. 145 the bone, the neAv-formed tendon runs over the articulating head of the thigh bone, this lever is lost. It is possible to make a perfect recovery, in cases of broken patella, by pro* ducing a close union betwixt the broken pieces in the way that I have described. If unfortunately the patella should be united by a long intervening ligament, Ave need not despair of bringing the muscles to accommodate themselves to this lengthening of their tendon. Often, though the thigh bone be remarkably shortened afl sr fracture, yet the muscular action of the limb is by exercise restored to full power. So in this instance, by exercise, the shortened muscles become capable of still fur- ther contraction. To facilitate this, Mr. Hunter recom- mended that the patient should seat himself on a table, and by giving motion to the leg, exercise these muscles, and that he ought to put a Aveight on the foot, to be increased as the power of the limb Avas regained. When the patella is fractured by a bloAV, as I have seen it by the kick of a horse, the connexions of the muscles Avith the joint, independent of the patella, keep it from being drawn up, as in the fracture I have already described. Here the injury to the joint is so great, that Ave cannot apply a band- age if it were required. We trust to the position alone, and are careful to bleed largely, and apply cold cloths so as to keep off inflammation. I have seen a very terrible accident folloAv the imperfect cure of the fractured patella. The bone had united by li- gament, and this ligament had incorporated with the skin in such a manner that it lost much of its pliancy. The poor man was carrying a burden and fell backAvard, the knee sunk under him, and the whole fore part of the joint was laid open by laceration. The case terminated in amputation of the limb. VOL. II. f! 146 FRACTURE OF Tilt FIBULA. FRACTURE OF THE FIBULA. In this sketch Ave may discover the nature of the case uf fractured fibula. In the first place, it brings to our recol- lection that the fibula does not support the weight of the bo- dy, and that it will never be broken by the shock of the body on the leg, unless the tibia first gives Avay. But remembering the constitution of the ancle joint, and that the fibula reaches doAvn upon the outside of that joint, it is pretty evident that the fibula can be broken only by a force directly applied to it, or by a twist of the foot. The first example, is Avhen a man falls, and the side of the fibula strikes a stone, over Avhich it is broken ; or Avhen he receives a bloAv on it; or Avhen his leg is pressed betAvixt his horse's side and the ground : thi^ is the simplest case. On the contrary, tlie fibula fractured in consequence of the foot being Avrenched on an uneven pave ment, is bad, because it is complicated Avith a strain, if not absolutely a dislocation of the ancle joint. When the heel only touches the ground, and the balance of the foct is not preserved by the resistance of the ball of the CRACTCRE OF THE TIBIA- 117 great toe, as the heel bone does not stand perpendicularly un- der the tibia, the end of the tibia, Avhich forms the malleolus intcrnus, bursts, or at least strains tlie deltoid ligament, Avhich unites it to the astragulus. Then the point of the fibula, B, forming the malleolus cxtcrnus, preserves the joint; or if the violence be great, it falls on this small bone in the direction of the dotted line, C, C ; so that it yields and breaks a few inches above the ancle, as at D. It folloAvs from tiiis, that Avhen Ave find a patient complaining of a strain of the inner ancle, avc examine the fibula, &c. if in any other instance we see plainly that the fibula is broken, Ave are careful to examine the inner ancle knowing that it must haA-e suffered in some degree, though there may not be a subluxation. A splint, Avhich will reach from the knee along the outside of the foot is prepared. In the holloAv of the splint, soft lint is placed, so that it equally supports the limb, an eighteen- tailed bandage is put under the splint; and tliis apparatus is so placed on the mattress, that the patient's leg being laid upon it, rests on the outside of the leg and foot. Having laid doAvn the leg on the splint, Ave examine again the degree of prominence of the inner ancle, and see that there is no tA\ist or obliquity of the foot. We are careful to notice, that tlie lower head of the fibula, and the side of the foot, are equally supported ; that the side of the foot is neither alloAved to hang over the end of the splint, nor too much pressed up; the bandage is then applied. From time to time Ave must exa- mine, lest the integuments of the inner ancle indicate too great a degree prominence in the tibia ; and also to see that the heads of the fibula, on which the limb tioav lies, are nqt suffering by the pressure. OF THE FRACrURE OF THE TIEIA. There is no difficulty in ascertaining the nature of the case,, when the tibia is fractured. The splints to -be applied are, first, one strong splint of Avood and leather, or of tin, which is to reach from the ou1r 148 FRACTURE OF THE TIBIA. side of the knee to the side of the foot. It must be made to receive the upper and loAver heads of the fibula, and holloAved to receive the prominent muscles of the outside of the leg. Another splint, shorter than the last, is to be adapted to the plane surface of the tibia, on the inside. This splint should be straight, and reach only to the heads of the tibia. The fracture of the tibia is often of the Avorst kind. The tibia is Aveak, Avhen we consider that the bone of one leg only, often sustains the whole weight and shock of the body. Like the thigh bone, it is often broken obliquely, because it receives the shock of the body perpendicularly on its shaft; but a worse circumstance in the state of this bone is, that it is covered only by the thin integuments. These-together, are the causes of the compound fracture of the tibia being so ve- ry frequent. They explain too, hoAV a compound fracture, of any other bones, which are deeply imbedded in the soft parts, can be Avith so much more ease converted into simple fracture than that of the tibia, viz. because the bones can be with- draAvn from the wound, and the integuments healed so much more easily. In the treatment of the fracture of the bones of the leg, there is only one thing more to be noticed in the way of a leading principle. I allude to the strength of the muscles of the leg, (muscles sufficiently strong to raise the Aveight of the whole body) being on the back part only ; and that immedi- ately on the accident, they are apt to cause the tAvo pieces of bone to stand at such an angle as to thrust the broken ends through the integuments. When during the cure, the broken ends of the tibia are made to project more and more at the shin, it is to be attribut- ed to the action of these muscles: and I conceive the best way of counteracting this, is to turn the limb, so that the heel may rest ©n the bed, while the toes are extended. This fully relaxes the muscles, while it gives the weight of the limb to counteract the curvature which is taking place. If the foot rests so that the toes are perpendicular to the heel, OF THE PERIOD OF CONFINEMENT. 149 then there is a stress upon the muscles of the leg; because the Achillis tendon is stretched. When the heel is made to rest on the bed, care must be taken that the foot do not fall outward, else the tibia will be tAvisted, and there will be an irregular prominence of the broken bone, on the inside of the shin. OF THE PERIOD OF CONFINEMENT. The last observation I shall make, regarding fracture of the limbs, relates to the length of time ay hich is necessary to the complete union of the bones. Different periods are pre- scribed to us before it shall be permitted that the patient should rise and use his limbs. Yet as far as I have been able to judge, the period of confinement ought not to be determin- ed, on the idea that fliere is any distinction in the commence- ment or termination of the process of ossification in the small- er and in the larger bone. The arm bone will unite as soon as the clavicle; and if the derangement of the surrounding parts, in the case of fractured thigh bone, be not much great- er than in the fractured arm bone, the greater bone will be united as soon as the lesser. But in giving liberty to the pa- tient, Ave should have regard to the use of the limb, and the stress to Avhich the bone is to be exposed. And then, in- deed, a proper difference arises between the bones of the arm, and those of the lower extremity; in the former, the bone bearing the weight of the limb only; in the latter, the bone sustaining the Aveight of the Avhole body and limb. Tlie bandage around the fractured clavicle, may be eased before the expiration of the month; but the arm ought not to be moved till the end of the month. Indeed tlie fractured humerus is not secure before the end of six weeks; and the same time is required for the bones of the fore arm. But Ave cannot alloAv the patient Avho has had a broken thigh b_one, to rice till after the six Aveeks; and then he is IdO FRACTURE- OP THE RIB. not to risk the weight of the body on the limb, but the limb is to be lifted and carried ; so in fracture of the tibia, the con- finement, or at least the precaution against resting on the limb, must be continued as long as in the instance of fractur- ed thigh bone. A difference may be observed in the time of the knitting of the fractured bones, ascribable to the state of the patient's health, and of course this will depend on air, diet, and consti- tution. When there is pain in the attempt to use the limb, it in- dicates, that the inflammation has not subsided, or that the natural action is not yet established. It ought, therefore, to make us cautious of using the limb. OF FRACTURES OF THE RIBS, STERNUM, AND PELVIS. The cases of fractured ribs, sternum, or pelvis, form a distinct class, because they resemble injuries of the skull more than the fracture of the bones of the extremity, in this, that they are dangerous only in so far as they do mischief to the contained viscera. OF A FRACiTRED RIB, The principal security of the bones of the chest is their elasticity. While the perfect elasticity of the cartilaginous joinings of the ribs remains, they are much protected, be- cause they yield, and by that means are saved from shocks which would break them; therefore, men are more liable to have fractured ribs in mature years. The ribs are often fractured by the person falling on a projecting corner, as of a table or chair. If he be reachuig to take doAvn something above him, and, stepping on a chair, he falls and strikes his side upon the corner of the chair, he will probably break his ribs. But I have had strong grounds of suspicion that patients have been braced up for weeTss without any necessity, and that both surgeon and pa- F-RACTURE OF CHE RIB. 151 tient have mistaken the pain of the bruised muscles, which lie on the side of the chest for the effect of fractured bone. To find Avhether the rib be broken or not, Ave must feel along its whole course : but if there be a particular spot very painful, and yet Ave do not distinguish the fracture, Ave must press in the rib at a part remote from this; Avhen, if it be fractured, it will yield, and produce the same pain as before; but if the bone be entire, there Avill be no pain, because the bruised integuments are not affected by the pressure. When the patient insists that there is something particularly Avrong, because he finds a sharp pain when he moves, it should still be considered whether this be not oAving to the bruised flesh of the descendens abdominis or scrratus magnus. You make him breathe, and there is no pain nor crepitation while you place the fingers on the part; you make him exert those mus- cles while the breathing is suspended, and then he feels the sharp pain caused by the action of the bruised muscles. When a rib is broken, Ave have only to keep it from mov- ing by preventing the motion of the chest in respiration; for it is unnecessary to attempt to keep the rib in its place, this being already accomplished by the neighbouring ribs, and by the connexion of the rib with the intercostal muscles. It is to be remarked, that the lower ribs have so free a motion, and so much elasticity, that they are not apt to be broken; while the upper one is defended by the clavicle. If a fractured rib be neglected, there is much pain, and much danger of inflammation in the chest, and, in the end, of caries of the rib ; for, by the motion of respiration, there is an incessant rubbing and grating of the broken ends of the ribs which prevents their union. I have dissected the body of a man who died in conse- quence of the fracture of two ribs; or rather, I ought to say, in consequence of their being neglected, the nature of the case having been misunderstood. There was an abscess under the pectoral muscle, and a caries of the ribs ; and, from th« irritation spreading Avithin the chest, much matter had been formed ia the cavity, awd even the pericardium contained 10*2 FRACTURE OF TH« RIB. pu-\ It will be said, that this extensive mischief could not have proceeded from the fracture of tAvo ribs had not the con- stitution been bad. This may be true, but from this we can only infer, that we should be more careful of such accidents Avhere there is constitutional weakness. The mention of this terrible consequence of neglected frac- ture, reminds me of the necessity of cautioning my reader against the consequence of a mere bruise of the chest. For, if abscess form under the broad muscles of the side, ca- ries of the bones and abscess Avithin, may be the consequence. It becomes our duty, therefore, to take precautions that matter do not collect under the pectoralis major or serratus muscles, and still more, that disease of the sternum does not folloAv con- tusion of that bone. A compound fracture of the ribs will not readily happen in consequence of the ribs projecting, for the ribs are, in truth, beaten in Avhen fractured. But owing to this latter circum- stance, the fracture of tlie rib is often complicated with a puncture of the lungs, or the rupture of the intercostal artery. If the lungs be Avounded by the end of the ribs, Ave know it from the frothy blood spit up. If a man dies from the ribs being beaten in upon the lungs, after surviving the immediate effect of tlie accident, the chest of that side is found full of bloody serum, and the lungs are compressed. When one or more of the ribs are fractured, a broad roll- er is put about the chest, and a split cloth is laid over the shoulders, to the ends of Avhich the roller is pinned. This bandaging forces the patient to breathe by the diaphragm and muscles of the belly, Avhile the chest is relieved from motion. The patient is then to be bled and put to bed. Bleeding, in tlus. case, not only prevents the membranes of the chest from inflaming, but, by diminishing the quantity of circulating blood, it relieves the respiration, because the extent and frequency of the distension of the lungs is pro- portioned to the quantity and velocity of the circulating blood. If there be a tickling cough, after the bleeding, opi- ates may be given. FRACTURE OF THE RIB. 153 If, after the patient is put to bed, there should come on a difficulty of breathing, with oppression in the chest, the end of the rib has probably pierced the pleura and penetrated the lungs, and the cavity of the chest contains air Avhich has es- caped from the lungs. If a tumour on the broken rib suc- ceeds to this, Avhich crackles under the finger, it is the emphy- sematous tumour, so peculiarly characteristic of this accident. The air has been forced from the cavity of the chest into the cellular membrane by the compressson of the chest, and it may be forced from the cellular membrane, Avhich covers the Avounded rib, over the whole body, until it closes the eyelids and distends the scrotum and integuments of the penis.' When the tumour merely betrays its nature, Avithout much inconvenience, we need not mind it; but if it increas- es rapidly, and is attended A\ith much oppression, punctures must be made in it Avith the lancet and the air pressed out, that both the cellular membrane may be freed from air, and the breathing from great oppression. While, in consequence of the accidental puncture of the lungs by the rib, the air distends the cavity and compresses the lungs on one side, the breathing and circulation may be oppressed and difficult; but still there is no interruption of the function of respiration: at last, hoAvever, by the great distension of one side, the mediastinum suffers, and the ca- vity of the other side is encroached upon ; and both the di- aphragm and the external muscles of respiration are imped- ed in their action. There is a sympathy Avhich pervades all the muscles of respiration, and even if the cavity of one side be distended, the muscles of that side cannot act, and their impeded action prevents the free motion of those of the oth- er side. Therefore it is that in emphysema there is, in the end, great anxiety and oppression, and the heart partaking of the influence, there is a feeble pulse and cold extremities. When the emphysema has proved the nature of the case, and the symptoms are thus pressing, Ave have to make an in- cision through the integuments and intercostal muscle, and YQY.. II. W F51 FRACTURE OF THE STERNUM. then puncture the pleura; by this means, the lunge of the wounded side will not be restored, but the play of the chest will become free, and the lungs of the other side will re- sume their action. When a rib is fractured, tlie intercostal artery may be torn; and should it happen that the artery is opened, and yet not torn across, it will bleed until the lungs are oppress- ed. Then Avith the common marks of haeuaorrhagy, the pa- tient finds himself greatly oppressed. He has a sense of suf- focation, and cannot lie down; and he breathes with con- tortion of the body, to allow the side of the chest opposite to that which contains the accumulated blood, to expand in respiration- It is, in this case,, the business of the surgeon to make an incision on the lower edge of the rib fractured, and a little further back than the broken point of the rib, taking care not to cut the artery which lies just under the rib ; and, having cut through the integuments and intercos- tal muscles, he ought to puncture the pleura. If he finds coagulated blood, he* will be tempted to enlarge the Avound, and introduce his finger to give vent to the blood and coagulum. If, after this, the blood accumulate again, it must be again evacuated, and a compress of sponge put into the wound, so as to press the artery against the rib. Should there be bloody froth discharged from the mouth, the lungs are Avounded, and then probably emphysema wiU unequivocally betray the nature of the case. FRACTURE OF THE STERNUM. The fracture of the sternum is a very alarming accident, both from the parts contained under it, and from the spongy nature of the bone. Like the ribs, during respiration, the sternum is in incessant motion; and the thorax being of a conical form, and the lower part admitting of a much great- er extent of motion than the upper part, it follows, that when the 6ternum is fractured across, there is a perpetual grating of the broken parts of the bone; the lower part of FRACTURE OF THE BONES OF THE FACE. 155 the sternum, being attached to the longer ribs, moves through a larger space than the upper portion. This rub- bing and grating of the fractured bones will produce inflam- mation and suppuration under the bone, viz. in the interior mediastinum. The danger from the mere motion of ordinary respiration is, of course, much increased Avhen the almost inevitable con- sequences of the accident supervene—irritation and inflam- mation in the chest, and a troublesome cough. From these considerations it will be understood how the patient, having happily escaped the immediate shock and injury to the thoracic viscera, is in danger of caries of the bone, and abscess under it; and it Avill be seen too, that the swathing, or bandaging of the chest is equally necessary here as in the fracture of the ribs, and that bleeding must be oftener repeated, and eArery possible cause of irritation avoided. It may happen that we require to draw out and pick away broken pieces of the sternum ; but fracture of the sternum, I am inclined to hope, does not ever require the trephine. We have however observed that the sternum is a very spongy bone, and therefore a part that is not always secure from scrophulous action Avhen it is bruised. The ca- ries of the sternum does, in some measure, hold analogy with the caries of the skull: it is the communication of the disease to the contained parts which we have to dread in both; and here it may be necessary, in some cases to apply the tre- phine to allow the free discharge of matter, or to take away a dead piece of bone which is the source of irritation. FRACTURE OF THE BONES OF THE FACE. The loAver jaw bone, being much exposed and moveable, is very often fractured. It is fractured by blows and falls, and is often found to be broken in two places. The reason of this complicated fracture we may see in the arehed form of the bone, and the support it has at the condyles; for if 156 FRACTURE OF THE BOXES UF-THE FACE. is impossible that one side of the bone should be beat in, Avithout some other part of the arch suffering, at the same time, in nearly an equal degree with the part which is struck. I cannot conceive how a difficulty can arise in ascertain- ing the nature of the case when the jaAV bone is fractured ; yet I have had occasion to set it after an eminent surgeon had dressed all the other hurts, but taken no notice of this— and authors insist on the marks of fracture as of the first im- portance. To examine the jaw bone, we place the fingers of the left hand on the angles of the bone, and then take hold of the alveolar part of the jaw bone in front, and endeavour to move it laterally. We in the mean while, keep the eye on the teeth, when we shall easily discover whether there has been any fracture of the lateral part of the bone : or Ave feel and press along the base of the jaw. In boys there is some- times a splitting of the lower jaw at the symphysis which is not so readily ascertained. The patient has perhaps fallen from a height; he has lost one or two of the front teeth, or they are loose, and a greater space than natural is betwixt them : By taking hold of the alveolar part of the jaw^ Avith the finger and thumb on each side of the symphysis, the fracture is at once ascertained by the usual symptoms. If a boy has split the symphysis of the lower jaAV, Ave re- place the teeth, and then bring the 6ides of the jaAV toge- ther. Wc then take a bandage Avith four tails, and cut a hole- in the centre of it, which will just admit the chin. The centre of the bandage being placed over the chinj the Iavo upper tails are brought round the back of the head, and the two lower tails are carried over the vertex. I have. found this quite sufficient to keep the jaAV bone and teeth in accurate contact. The bandage may be made more secure by covering that part of it which embraces the face with an adhesive plaster. If it be thought necessary to tie the teeth together, the Avhole of the front teeth ought to be in- cluded in a cord of silk; but this cannot be done, if the teeth have been shaken and are.loose. FRACTURE OF THE BONES OF THE FACE. 15i In the case of fracture of the base of the jaw, and especially if there be a fracture of both sides, it is more difficult to keep the pieces in their place. This is owing to the same circum- stance that disorders all other fractured bones, viz. the une- qual action of the muscles. We may recollect that the mus cles which close the lower jaAV are poAverful, and are fixed into the coronoid process, or the angle of the jaAV. The mus- cles which draw down the jaw are Aveak, but inserted into the bone more forward, so that they operate with a longer lever. These different insertions of the tAvo classes of muscles cause a distortion of the jaw bone, Avhen it is broken as Ave have de- scribed ; for then the back part of the bone is held firmly up, while the fore part is pulled down by the muscles of the throat and the digasti icus. If the teeth be very regular, and those of the upper and loAver jaAV correspond, those of the upper jaAV serve the pur- pose of secure splints, when the base of the jaAV and chin are bandaged. If the patient has lost a tooth previously, and Avhen the pieces of the broken jaAV are brought together, there is a deficiency or inequality in the teeth, then a piece of cork may be adapted to the teeth of each side in such a manner as to serve the purpose of a splint. The chin being brought up, and the hindmost pieces of the bone pushed back so that there is an adjustment, the jaw is to be secured on the outside. A piece of pasteboard is to be cut into such a shape as may be accommodated to the chin and jaw : It is to be notched round the edge, and then moistened, that being applied on the lower part of the chin it may be brought up on the base and sides of the jaAV on both sides. Over it is to be applied the four-headed roller as already described. There can be no occasion, in this case, for feeding the pa- tient with a pipe, or attempting to nourish him with clysters. Perhaps he may fortunately on tlus occasion have lost one of his teeth, and tlirough the interstice he can suck his nourish- ment. But if the teeth be altogether perfect, in that case, rather than that he should have to live altogether on liquid, the 158 . FRACTURE OF THE BONES OF THE NOSE. cork splints may be laid along the teeth, which, Avhile they give firmness to the bandaging, alloAv an interstice in front for giving food. FRACTURE OF THE BONES OF THE NOSE. No doubt the ossa nasi suffer fracture, but they are oftener in a manner dislocated, that is to say, one of them is beat in, Avhile the other lies over it. When they are fractured and entirely beat down, the shock sometimes reaches the septum nasi, and it is also fractured. Nay, a Avorse effect may yet be a consequence of a bloAv on the nose. It has happened that the delicate cribriform plate of the ethmoid bone has been fractured and pushed up on the brain, from the shock com- municated to it through the septum ! The arch of the nose is to l>e raised by a strong probe co- vered with lint: by putting oil on the little finger, we may push it into the nostril, so as to replace the cartilage and bone of the septum ; tubes of any kind, I believe cannot be intro- duced so as to support the broken bones. When the bones are replaced they will not readily move from their place; there are no muscles, no motion of the part to change their position, and very soon a SAvelling of the nose and membranes comes on which supports them sufficiently. If, in consequence of a blow on the nose, and a fracture of the ethmoid bone, there should succeed discharge of matter with symptoms of a beginning affection of the brain, then ought we to probe gently and perhaps pull upon the perpen- dicular plate of the ethmoid bone, that we may bring down any part of the horizontal plate which may be irritating the brain. In the mean time, by every means in our power, we ward off inflammation. Happily the case is not likely to «?ccur. OF DISLOCATION. 159 CHAPTER VIIT. OF DISLOCATION. .Luxation or dislocation is the displacement of the articulating surfaces of the bones. Dislocation is the conse- quence of a tAvist of the limb not the effect of direct injury to the joint Avhich is deranged. Mistakes both in the diagnosis and in the efforts to reduce the bonep, will arise from overlook- ing this very obvious fact. There is a division of dislocation into kinds. Dislocation implies that the articulating sur- faces of the bones no longer correspond in any degree, that the bone is entirely displaced ; as when the head of the hu- merus lies in the axilla, or the head of the femur has been forced from tlie acetabulum, and lies on the back of the ilium. Subluxation is the derangement of the articulating heads of the bones, while yet they are in contact and rest against each other. The entanglement of the articulating processes of the vertebras of the loins is a subluxation : there may be a subluxa- tion of the knee, or more frequently of the ancle joint. Then we have the distinction of simple and compound dis- location, analogous to that of simple and compound fracture. In compound dislocation there is a wound of the integuments with dislocation of the bone ; and it is dangerous, as there is united an inflamed and suppurating Avound of the soft parts with the wound of a joint, which consists of parts Avidely dif- fering in economy, parts sIoav to inflame, but of which the inflammation Avhen excited is violent in degree. Diastasis is a mere separation of the bones. There is yet another distinction, viz. into old and recent dislocation. This is a distinction sometimes important to tlie I GO OF DISLOCATION. surgeon, for lie has to consider the consequences of the bone? remaining long displaced before he determines on attempting to reduce the dislocation. I need not remind my readers of the nature of the ligaments and cellular substance. The ligaments are dense, white, strong, and possessed of little vascularity; they are of two kinds ; first, such as are Aveak, but destined to preserve the sinovia, and to separate the articulating surfaces from the sur- rounding parts; these capsules are very weak. The second kind possess no elasticity,- pass from point to point of adjoin. ing bones, and are the strength of the articulation. Perhaps with these may be classed such tendons of muscles as surround the joint, and are incorporated with the capsular ligament. Now it is possible, that one side of a joint only is sprained, the stronger uniting ligaments are partially lacerated, and there is a weakness and yielding of the joint, or there is, per- haps, a subluxation. But when there is a dislocation, and actual displacement of the bones, both the capsular and unit- ing ligaments must be torn ; sometimes in the Avhole circle of the bones, always for more than one half the circumference of the head of the bone. From this it folloAvs, that there can- not be a noosing of the head of the dislocated bone in the slit of the capsule, as some have imagined to be the case, Avhen the reduction has proved difficult. (See further under the head of Dislocated Shoulder.) In dislocation, then, the head of the displaced bone lies among the cellular membrane, and is either lodged betAvixt the muscles, or presses upon a bone. Where the smooth ar- ticulating cartilage is in contact Avith the cellular membrane, it presses and condenses the cellular membrane so that it be- comes a substitution for the natural capsule, AA'hile the toiu capsules and ligaments adhere to the surrounding parts. If the head of the dislocated bone presses on a flat bone, as the os innominatum, or scapula, an imperfect articulating surface is at last formed. In the mean time, the head of the bone no longer resting in the natural cavity, the surrounding soft parts encroach upon the cavily. and adhesions fr-m a parti- OF DISLOCATION. l^-l tion betwixt the head of the bone and its former place. Be- sides, there is another unfavourable circumstance, the muscles adapt themselves to the state of the bones, and are permanent- ly shortened, so that they strongly resist the reduction. The meaning of the distinction into recent and old disloca- tion will noAv be understood. WThen the dislocation is of long standing, the neAv adhesions are to be torn up, and violence must be done to the limb, as great, perhaps, as that which caused the displacement of the bone, before it can be reduced: while in a recent dislocation there is no obstruction to the re- duction but in the muscles, or natural ligaments. In speaking of the degrees of derangement of the joint from violence, it is proper to mention sprains, and to explain that degree of weakness Avhich remains after them. A sprain is a momentary derangement of the articulating surfaces of bones, by Avhich a stress is put on the ligaments, and those of one side are either partially torn, or they are stretched so that they inflame. In every sense of the word I deny that the capsules and ligaments of a joint are insensible —sensibility to pain is the grand safeguard to the body; and, although the joints do not feel in the same manner and de- gree with the skin and superficial parts, yet they have that degree of sensibility which suits their, condition ; is there not excruciating pain Avhen a man sprains his ancle ? and yet the pain is not in the skin, it is quite different from the shock of a superficial part; and except the skin, there is nothing to suf- fer pain but tendons, and sheaths, and ligaments, which phy- siologists' say are insensible. Physiologists have erred because they have not perceived the end of this sensibility, and the variety in kind, as well as in degree, Avhich is suited to tlie functions of the several parts. If the end of a bone, and the capsule, were sensible as .the skin or eye, or other delicate or- gan, their common and necessary function Avould lay the foundation of inflammation, a greater degree of sensibility would be the consequence, and the evil Avould increase until the mobility of the joint Avere destroyed. In the common and necessary motion of the joints there is no sensation, no injury VOL. IT'. -x Jte On DISLOCATION. from the friction of the parts. But, if in tlie violent and ir- regular motions of the joints there should be no sensation com- municated, then Avould there be an absence of the governing principle, and no restraint, and no means of renovation. We may see now, why, in experiments on the tendons and liga- ments by pouring acids upon them, and pricking them with needles, the animal gives no sign of pain ; and yet in sprains, and dislocations there is extreme torture ;—Ave wonder only that the distinction should have been overlooked. To preserve the natural state of a joint that inferior degree of activity of vessels only is necessary, which, perhaps errone- ously, we call a weak action. However, it is important to observe, that whenever this na- tural state of action is changed, there is also a change in the nature of the part. Tlie pain I have described is folloAved by its usual effect, inflammation: the ligaments when inflamed lose their density and firmness, they swell, become weak, and acquire a new kind of sensibility, and no longer bind the bones with their former strength. This is the explanation of the weakness of a joint after a dislocation, or a sprain : Avithout this increased activity of vessels there could be no regenera- tion of the ruptured parts; injury to a joint would be like the breaking of the parts of a machine which possess no pro- perty of restoring themselves. Nothing, however, is more dif- iicult, than to change this Ioav degree of continued inflamma- tion, and to restore the state of the parts to their natural den- sity and firmness. In the scrophulous constitution there is, unfortunately, a tendency to this inflammatory action in the joints, which it is very difficult to allay. It is not bleeding and purging which will reach a local disease of this kind; far less will this do good if there be any constitutional tendency to scrophulous actions. We may take a hint from quacks and bone-setters ; I have knoAvn them remarkably successful by employing severe and continued irritation on the surface Avhile they have forcibly moved the stiff and pained joint. But this has been after the surgeon has exhausted the patient OF DISLOCATION. 1(53 by ineffectual applications, or, in other words, after all active inflammation has subsided. To ascertain the nature of the accident when Ave have rea- son to think there is dislocation, Ave must consider these points: 1. We, perhaps, find the joint much discoloured, and marks of a bloAv received upon it This implies, though it be no absolute proof, that the bones are not dislocated, but only the joint bruised; because, as I have said, it is the long lever of the bones receiving the force upon the extremity dis taut from the joint, which does violence to the connecting li- gaments. For example, if there has not been a blow on the shoulder, but the patient falling on the Avrist, has pain and lameness of the shoulder joint, then sprain or dislocation qf the shoulder is the probable cause of the pain and incapacity; if, on the contrary, there shall be evident marks of a bruise on the shoulder, it is probably not a dislocation. 2. The knoAvledge of the natural form and position of the limb will often enable us Avith a glance of the eye, to dis- cover the distortion caused by dislocation. Generally the limb is shorter, though sometimes it is lengthened; when Avith this there is joined a stiff and aAvkward position, from which the limb is not moved Avithout great pain, and Avhen. upon examining it more particularly, there is a rigidity of one set of muscles, the dislocation is ascertained. We consider the new position of the head of the bone; the effect of this change, on the muscles inserted into it; we feel those muscles, and they are rigid like cords; and this, Avith the circum- stance of the accident having produced this immediate conse- quence, is decisive of the nature of the case. There may oc cur a contraction and stiffness of the muscles from spasm, pro- ducing a resemblance to the unnatural position of the dislo cated limb, but there will not be the actual distortion pro ceeding from the new position of the bone, and the change in the angle of insertion of the muscle ; there will be no shorten- ing of the limb. In dislocation, the motion Avhich is allowed to the limb is often interrupted and unequal. There is also a particular checking occasioned by the head of the bone strik- 164 OF DISLOCATION. ing against a flat surface, not rolling in its natural socket. But let us recollect, that there may be a roughness and im- peded motion in the joint, occasioned by inflammation having diminished the natural secretion of sinovia, Avhere there is no degree of dislocation. Another diagnostic may be sometimes found in the pressure of the displaced head of the bone.—I not only mean that we may sometimes discover the displaced head of the bone, but that the effect of its pressure on the neighbouring parts de- clares to us its new position: as for example, when the head of the humerus, resting in the axilla, presses on the nerves, or artery, or causes numbness of the hand and arm, or Aveakness in the pulse at the Avrist. Before Ave attempt to reduce a dislocation it behoves us, in a particular manner, to think of the position in which the patient stood, and the nature of the force Avhich displaced the bone. It must be very evident, that the bone ought to be brought to the same position in which it received the im- pulse which dislocated it, before it can be easily reduced. We shall find examples as Ave proceed, Avhere the ligaments impede the reduction, oAving to the neglect of this plain rule. Tlie muscles too Avill ahvays, in a certain degree, impede the reduction. On attending to the origins and insertions,or, in other Avords, to the action of the muscles, it is possible, by bending the joints, and relaxing the flexor muscles, to free the head of the bone from its confinement. It is a commonly re- ceived opinion, that the action of the muscles is not ahvays direct against the elongation of the limb, but that they bind the heads of the dislocated bones together, so that the pro- cesses of the bones check into each other, and absolutely pre- vent any degree of direct force from disentangling these pro- cesses, or stretching the limb. Next in importance to the relaxation of the muscles, and the due direction of the shaft of the dislocated bone, is the providing of proper laques; but especially applying them avcII, and to their proper place. The two bones, whose sur- faces are dislocated, must, if possible, receive the whole force. DISLOCATION OF THE CLAVICLE. 165 To reduce the shoulder joint, the chief difficulty is to secure the scapula; and the efforts to reduce the dislocated thigh bone are often ineffectual oAving to the pelvis being left free, and only the other thigh secured. It is customary, and right, to fatigue the muscles of the limb before the full effort is made to reduce the bone. The tackle is pulled tight, and the force gradually increased ; the surgeon feels the progiess of the head of the bone, and directs the efforts of the assistants; and by rolling the head of the bone, and sometimes by lateral pressure, (such as may serve to disentangle the processes of bones), he assists their efforts : or, Avhen the bones have been brought as near to a corres- pondence as the direct pulling on the limb will affect, by a sudden effort he changes the angle of the joint, and Avith the poAver of the long bone, as a lever, reduces the dislocation. The marks of the reduction may be learned from what I have said of the signs of dislocation; or they may be sum- med up by saying that the limb is brought to its natural state, and the patient suddenly gains the power of complete motion. The bone Avill often return Avith a distinct and au- dible jirk into its place, such as might be expected from the smooth round head of the bone being drawn over the mar- gin into the well-luhricated holloAv of the socket. The free- dom from the painful and unequal extension of the muscles, makes the patient satisfied that the bone is reduced, before the surgeon can be aAvare of it. The mechanical poAver of the double pulley ought to be preferred to the force of many assistants, from its being so much more easily managed and directed. But let it be re- membered, that the surgeon may make a miscalculation of this mechanical increase of power very hurtful to the patient. DISLOCATION OF THE CLAVICLE. Although the clavicle be united to the sternum by strong ligaments, yet it is a weak joint, seeing that it is small to bear the Aveight, and allow the free motion of the upper ex- 166 DISLOCATION OF THE CLAVICLE. tremity. In truth it is the weakness of the bone more than the strength of the joint that prevents the dislocation of the clavicle at the nearer extremity. When the clavicle is dis- located from the sternum the nature of the accident cannot be mistaken. The intention in the treatment is also sufficient- ly evident. The shoulder is to be bound moderately back, and the arm slung, whilst a compress is to be put on the clavicle, and the roller brought round from under the arm pit of that side obliquely across the shoulder and side of the neck, in order to press down the end of the clavicle into its place. The clavicle is sometimes dislocated from its connexion with the acromion scapulas. This dislocation may at first sight be mistaken for a dislocated humerus, until the nature of the injury being understood, we find that the force used has not been such as is likely to turn out the humerus from its place. And although their appears to be at first that holloAv under the projection of the shoulder which implies the dislodgement of the head of the humerus from its place, yet presently we discover that this is only occasioned by the comparative projection of the scapular end of the clavicle; or rather more strictly speaking, that the shoulder has fallen nearer to the breast, Avhile the clavicle is left Avith its further extremity projecting; we find that the humerus admits of easy and uninterrupted motion. I have said that the clavicle projects, yet properly this is rather the receding of the Ecapula and humerus, which are now no longer kept off the breast by the clavicle. With more propriety therefore in this instance, we should term the accident the dislocation of the scapula than of the clavicle, as the clavicle remains in its place. The operation is to re- place the scapula: this is to be done by holding the arm and scapula in due relation to the clavicle until the sjpica bandage be applied over the shoulder joint. When Ave suspend the fore arm, and put a pad in the arm pit to keep the scapula at its proper distance from the sternum. DISLOCATION OF THE HUMERUS. 16? DISLOCATION OF THE HEAD OF THE HUMERUS. It is not in general a shock communicated to the joint which dislocates the humerus from the scapula, but a t\vist of the arm. If, for example, a boy stand holding a horse by the bridle, and the horse tosses his head, then the boy's arm is raised, and the head of the humerus is displaced from the glenoid cavity of the scapula. Or again, if a man slip his foot and fall, and if to save himself he stretches out the arm, then the full weight of the body being sustained by the hand, and operating with the advantage of the long lever of the arm, it turns the head of the humerus off the articulating surface of the scapula. It will be remembered, that the very free motion of the scapula is the safe-guard of the shoulder joint; for the sca- pula following the motions of the arm prevents the arm bone from rising to an angle Avith the glenoid surface, which would in a manner facilitate dislocation. This gliding mo- tion of the scapula keeps the humerus, even in its highest elevation, still perpendicular to the glenoid cavity. Still the position of the arm favourable to dislocation is when th arm bone is raised to its utmost limits, and until it be checked by the acromion process of the scapula. The, 168 DISLOCATION OF THE HliMERLS. bones then stand in the relation to each other that is here represented. A is the scapula. B the acromion scapulas. C the humerus: Avhile D may represent the loAver part of the capsule. If the arm be thus raised, and there is a force suddenly raising the arm further, a spasmodic action of the muscles inserted into the scapula fix it, and then the arm bone, C, comes in contact with the process, B, as here re- presented, and the force operating on the long lever of the arm, the head of the bone bursts through the capsule, D; tears the ligaments of the joint, and lodges in the axilla. In- deed, as to the place of the head of the humerus in disloca- tion it depends on the direction of the force combined Avith the operation of the muscles. If, for example, while the hu- merus is made to act like a lever, tearing up the ligaments of the joint, it at the same time receives an impulse in the line E D; that is in the direction of the shaft of the bone,. then will the head be urged deep into the axilla, or under the pectoralis major muscle.

D, The humerus in outline representing the consequence of pressing the elbow to the side, viz. that the head rises and presses against the neck of the scapula. DISLOCATION OF THE HUMERUS. 169 The signs of dislocation of the shoulder are these :— 1. There is a hollow, in tlie middle of the deltoid muscle, and directly under the acromion process; because the head of the humerus is removed from the glenoid cavity of the scapula, and no longer serves to give roundness to the shoulder. 2. The head of the humerus is to be felt in the axilla. 3. The elbow cannot be pressed to the side Avithout diffi- culty xand pain. (This however is an indication Avhich be- comes less distinct in old cases.) 4. The patient cannot make the circular motion of the arm. He raises his hand to his head aAvkwardly, and with pain. 5. There is an unusual bend or depression near the middle of the arm, from the change in the angle of insertion of the deltoides in consequence of the new direction of tlie bone. 6. The fore arm is not freely extended, and there is a tense- ness in the biceps muscle. This proceeds from the origin of the long head of the biceps retauiing its hold on the edge. of the glenoid cavity, while the tendon being engaged in the groove of the humerus must follow that bone, and consequent- ly draw upon the belly of the muscle. 7. There is a numbness of the arm sometimes, and the pulse may be oppressed, or there may be oedema of the arm. This arises from the head of the humerus pressing on the ax- illary artery, or veins, or plexus of brachial nerves, and de- pends therefore on the accidental position of the head of the bone. POSITION OF THE HEAD OF THE HUMERUS. 1. No force can be applied in a-direction to dislocate the humerus, and push its head behind the scapula, for this very evident reason, that the chest prevents the necessary position of the humerus. 2. Neither can the arm bone be dislocated upAvards, be- cause of the protection afforded to the joint by the promi- nence of the acromion and coracoid process; but chiefly, I believe, this is to be taken into consideration that there can vox. u. Y i?0 DISLOCATION OF THE HUMERUS be no tAvist given to the bone when the arm is by the qjde* consequently the ligaments are not burst up. 3. But the head, of the bone may be lodged foj ward, that is, the arm may be bent backward, the ligaments burst up, and the force such as to direct the head of the humerus un- der the pectoral muscle. 4. DoAvmvard, or downward and forward, is the most com- mon position of the head of the humerus Avhen dislocated. The reason is already explained, viz. that the arm can be cx» tended in the opposite direction, that is upward and outAvard, and in that direction there is no check to the motion of th$ humerus but in the processes of the scapula: Avhich however, being unequal to resist the force of 50 long a lever as the arm, serve only to throw the head of the humerus off the ar-r ticulating surface of the scapula, and to tear up the ligaments of the joints. OF THE REDUCTION IN SIMPLE CASES. We 6hall not at present stop to consider whether therq ought properly to be any distinction made in dislocation of the shoulder joint, but merely observe, that often a slight force by the hands of the operator is sufficient to reduce it. The cases of difficulty I hope shall presently be explained. The patient is seated in a chair; a table-cloth is put un- der the arm-pit and round the chest, while the ends are tied to some secure post or bench; a hand-towel is then put over the shoulder so as to press the acromion and scapular end of the clavicle; the ends of this cloth are put round the larger table-cloth, where it crosses the back and breast; they are drawn tight there and secured. Something in form of a noose is now put above the elboAV joint, and perhaps a hand-towel is the best thing we can use. It is twisted like a rope, and then applied in the form of a sailor's knot, in such a manner, that the more the ends are DISLOCATION OF THE HUMERUS* in jhilled the more securely it grasps the arm*. It must take firm hold of the condyles of the humerus. An assistant standing a little above the level of the patient, takes hold of these laques, and pulls gently at first, increasing the force gra- dually to the utmost. When the arm of tlie patient is some- what fatigued, the surgeon takes hold of the arm Avith the right hand, placing the palm of his left on the top of the patient's shoulder; he directs the dislocated bone into that line in which it was dislocated, i. e. elevated and a little backAvards ; and increasing the force, he brings the arm round until its direction is forAvard and upAvard, Avhen the bone Avill be in general reduced. The reduction is known by the audible jerk Which the bone makes ; by the immediate ease of the patient, by the holloAv under the acromion being filled up, and by the easy motion of the arm being restored, During this operation it may be useful to bend the elbow joint, and use the fore-ann like a lever to roll the humerus, which will in the first instance serve to disentangle the head of the bone from its neAv connexions, and in the course of its motion towards the glenoid cavity facilitate the tubercles passing the edge of the scapula. *WTren the humerus is draAvn out to that degree that the head is nearly on a level with the glenoid cavity of the sca- pula, and yet it does not slip into its place, we must vary the position of the arm by drawing the arm more upward, or what is the same thing, by allowing the shoulder of the pa- tient to drop more, and the upper part of the trunk to fall a little to the side. Though I have found, that when the head of the humerus lodged against the margin of the glenoid cavity, that it was reduced by suddenly depressing the elbow, and lifting the head of the bone with my fore-arm, pressing upwards in the axilla, yet I can see strong objections to it; nay, often instead of facilitating the reduction, this position of the humerus • It is a knot formed by twisting the cloth into two nooses, through which the arm is put, and on drawing the ends we have the firmest hold possible. 172 ACCIDENTAL REDUCTION OF THE HUMERUS. dowmvard directly opposes it. I shall first state the fact of the great difficulty which sometimes occurs to the reduction of the dislocated shoulder, and then explain it from the con- sideration of the anatomy. We are told that cases have occurred where no effort has succeeded in reducing the humerus, until by some unintentional motion, and by accident, the head of the bone has slipt into its place. What are wc to think of this ? not that the reduc- tion is an accident, and that Ave are to move the arm in vari- ous directions until by a lucky chance the dislocation is reduc- ed ! A little further enquiry teaches us that there is a certain position in which the bone resists, and one also in Avhich it as certainly yields. I have experienced this in the living body, and produced the same effect in the dead body. I have found that upon pulling the arm directly out from the body, horizontally, that not the smallest progress was made ; but that at last the patient's body yielding somewhat, the effect was, that in relation to the scapula the position of the humerus Avas considerably raised, and that then the head of the bone slipped into its place. The explanation Avhich has been. given of this accidental reduction is, that the head of the humerus when it was dis- placed burst through the capsular ligament Avithout tearing it entirely away, and that the head of the bone was retained noosed in a slit of the capsule, so that it could not be reduded unless the arm was brought exactly to the position in which it was when displaced. To this it lias been objected,~ that the head of the humerus does not merely burst through the capsule when dislocation takes place ; the capsule is tern largely aAvay from the edge of the glenoid cavity, so that the head of the bone cannot be retained in the slit of the capsize. It has been very resolutely affirmed, that the cause of this dif- ficulty of reduction is to be found in the muscles : that the head of the bone when it burst from the capsule was pushed through betwixt the teres major and the subscapularis in this manner. REDUCTION IMPEDED BY THE MUSCLES. 17S A, the clavicle. B, the scapula. C, the head of the humerus thrust betwixt the muscles. D, the subscapulars and teres minor. E, the teres major. F, is pari of the la- tissimus dorsi. G, the deltoides. H, the coraco-brachiafis. I, the biceps. This sketch was taken from a dissection after an experiment on the dead body. It proved more than is shown here, for on pressing down the arm bone to the horizontal direction I found that the reduction was prevented, and keeping the parts in the exact position. I cut away all the muscles, and still the humerus was retained checked ; but then what made the obstruction became apparent, viz. the upper part of the capsular ligament. But T must now explain in what manner the capsule is torn. I74f DISLOCATION OF THE HUMERUS. In this sketch the scapula and humerus are represented in the relation to each other as if the humerus Avas just slipping from its position. Here it is evident, that as the line C, from the upper margin of the scapula to the nearest point of the attachment of the capsule to the humerus is shorter than the line D, which encircles tlie head of the bone, so will the side of the Capsule AA'hich answers to C, be less stretched than the loAver part at D, during dislocation. Indeed the upper part of the capsule of the joint is not more stretched when the hu- merus has slipped from the articulating surface of the scapula. than when the arm hangs naturally by the side. If in th$ dead body we cut the lower part of the capsule of the joint the humerus is easily dislocated, but if we cut the upper part only, and let the lower part of the capsule remain entire, it is very difficult to dislocate the bones, and not without tearing the loAver part of the capsule. POSITION OF THE HUMERUS AVHEN DISLOCATED. 1T5 In truth, Avhen the humerus is dislocated this is the state of the bones and ligament. A, the scapula. B, the humerus dislocated. C, the capsule still entire on the upper part, though completely torn aAvay on the lower and fore part. D, the rough protuberance of the head of the humerus checked under the neck of the scapula. And now it is evident, that when the arm is brought to the direction of the line E, the capsule C, resists the depression of the bone, and throws up the point D, under the neck of the scapula, and the greater the force employed to stretch the arm the firmer are the humerus and scapula tied together at the points C D. But if on the con- trary we desist from this direction of the force horizontally, and raise the arm into the direction of the line G H, then the capsule C, is relaxed, and the point D, escapes from under the neck of the scapula and the bone is reduced. In conclusion then, though by placing the fore arm in the axilla of the patient, and raising the head of the humerus while we depress the elbow, we facilitate the reduction when no part of the capsule remains, yet if there remains any shred of the capsule this manoeuvre will directly impede the reduc- tion. We must on the contrary elevate the elbow, or let th« body of the patient fall somewhat more laterally, in order to facilitate the reduction. 176 DISLOCATION OF THE HUMERUS. There is no occasion for any bandage being used after re- duction to keep the humerus in its place, that is effected by the bracing of the muscles round the joint. If any thing be required it is that some check may be given to the raising of the elboAV too far from the side until the ligament has united. The surface may be rubbed with warm stimulating oils, and the arm gently and regularly moved. In this violent operation one can imagine, that if the axilla- ry artery Avere at all diseased it might be torn; but I have not. known of such an accident, though I have knoAvn such an ecchymosis succeed the operation of reduction, as would im- ply the rupture of some considerable vein. In employing the ambe in the NeAvcastle Infirmary both the axillary artery and the muscle have been torn! so that they were obliged to am- putate on the instant: one would expect that such a proof Avas not Avanting to show that it was not the muscles but the ligaments which caused the very great difficulty in reducing the bone in dislocations. Having proceeded thus far in Avhat I had to say on the dislocation of the shoulder, I recollected that there Avas much ingenious observation in Mr. Hey's Surgery on this subject; I find too that there is much for animadversion. The stu- dent finds an example in that work under the head of Dislo- cation, of what most surgeons have experienced in their prac- tice, a Avant of principle, and consequently a Avant of method. In the three first cases we have an example of the easy re- duction where the bone, we might almost say spontaneously, falls into its place. The conclusion Mr. Hey draAvs is, " that reduction might sometimes be effected with less extension than is commonly used, and consequently Avith less pain:" it ap- pears to him, " that the muscles Avhen so far stretched as te be rendered painful, begin to re-act and resist the efforts made for their further elongation." The fact seems to me to b« still this; it is the direction of the humerus more than the force employed which occasions the seeming difference in the various cases of dislocation. DISLOCATION OF THE HUMERUS. Mr. Hey observes, « When the head of the bone has desert- ed the axilla, and has slipped under the pectoral muscle, I have observed that it is brought back into the axilla the more readily if the extension is made in a direction opposite to that in Avhich it has passed from the axilla. This effect is* often greatly promoted by making the extension with the arm elevated as Mr. White has advised. But Avhen the head of the bone has advanced far under the pectoral muscle, strong extension by closing the passage through Avhich the protube- rant part of the bone should return, often prevents instead of promoting reduction." p. 291, The first part of this quotation resolves into the advice, that the bone must be elevated to the position in Avhich it was wdien dislocated, before the force be used to extend the arm. The second part of the excerpt has, however, a refer- ence to the opinion that the bone passes through a noose, Avhich I hope I have shown to be a groundless supposition. In Case IV. Ave have these words: " The body being sup- ported, and counter extension made by means of a broad towel put round the thorax of the patient, the extension of tlie arm Avas made by three or four men, first in a direction at right angles to the body, and Avhen the extension Avas in its greatest degree, by pulling the arm towards the ground at an acute angle Avith the body, while I attempted to raise the head of the bone by my hands placed as near it as I could. This method failed; so did that Avith the heel in the axilla." So I conceive the attempt in this Avay will ever do if the state of the ligament be as I have alleged. Then it will be asked, hoAV does it happen that simply by extending the arm at right angles with the body the dislocation is so often re- duced ? I believe the fact to be, that the arm is not at right angles with the body in most of the cases thus reduced, but that the counter extension being made imperfectly, the body of the patient falls so far towards the assistants, that the in- clination of the humerus is changed to that direction which I have so much insisted upon as being necessary to reduction. For it is not the position of the arm, or of the patient's body, VOL. IT. Z 178 DISLOCATION OF THE HUMERUS. but the relation betAvixt the humerus and scapula that is im- portant. There is a method by Avhich the operator's neck is yoked to the patient: a toAvel is put under the arm-pit and over the surgeon's neck, who raises himself while the assistants pull; he thinks he assists the reduction by raising the humerus over the edge of the glenoid cavity, Avhile he is only pressing the head of the humerus against the neck of the scapula. This is someAvhat more harmless, but no less unscientific, Avith the operation of the ambe, or the dragging by the wrist a^ ith the heel in the axilla. In all these cases it is still locking of the bones, or the ligament which resists, by preventing the exten- sion of the limb. I return to Mr. Hey's Cases :—In Case VI. after several methods had been tried, as Freke's improved ambe, that by the toAvel round the operator's neck, &c. he proceeds, " Mr. Lucas and Mr. Jones aftenvards tried to reduce the bone by the heel in the axilla, and Mr. Lucas perceived a noise during one effort as if the bone had returned to its place. While the last method was in use it occurred to me, that extension made in a direction parallel to that of the body Avas not likely to succeed, while the head of the bone lay so deeply sunk, and behind the pectoral muscle. I therefore advised, that one person should extend the arm at right angles to the body, by a hold of the fore-arm, placing his foot against the side of the patient's thorax. In this Avay the person making the ex- tension Avould not only have a firm support, but would also be enabled to repress the loAver part of the scapula by his heel placed against it. That during this extension another per- son lying by the side of the patient, should place his heel against the upper part of the os humeri, as near to its head as possible, and should push it in a direction parallel to that of tlie patient's body. By this method the bone altered its situ- ation with, such a noise as is usually heard in reductions, and we- concluded that the head of the bone had re-entered the socket ; but Avhen the arm Avas brought close to the patient's .ide, Ave found that the head of the bone Avas still in the DISLOCATION OF THE HUMERUS. 1:9 axilla. This appearance of success encouraged us however to repeat the operation, but the event Avas the same. Wre now • imagined that some portion of the capsular ligament might be folded so as to be intercepted botAvcen the head of the bone and the glenoid cavity, into Avhich a\ e judged the bone to have been twice brought. On this supposition, after making the reduction the third time, the os humeri was moved in various directions* sometimes upon its oavii axis, sometimes upwards and doAvmvards, before Ave attempted to bring the arm to the patient's side. Also while the extension was con- tinued, a flattened ball of low Avas thrust up into the axilla by the heel, to prevent the head of the bone from retiring again into the axilla ; the arm was. then brought into contact Avith the patient's side, &c. by this means the reduction Avas com- pleted and confirmed." See p. 297. Remarks. This is a just picture of the bustle, the varied and ill directed efforts a\ here there is no principle drawn from anatomy to direct the operator. The next Case Mr. Hey gives, is one where after some inef- fectual endeavours the bone was reduced by the assistants elevating the patient by toAvels round the arm from his seat on the ground, and then, ay bile the arm Avas thus stretched, carrying it forward. Further experience must determine, says Mr. Hey, Avhether this method of reduction is superior to those which he has mentioned. Now Ave believe that what is called experience has kept this part of surgeiy in unusual darkness. Let any person take the dissected shoulder joint in his hand, and there will be no occasion for further experience to inform him that this is the best of all the methods employed by Mr. Hey. The reason I hope I have sufficiently explained already. One more observation I am led to by Mr. I ley's Avork ; in page 304 he says, that in several of the cases the counter ex- tension was applied so as to press back the inferior angle of the scapula, contrary to the directions given by Mr. Brorn- field, Avho used to cause the acromion to be pushed backAvard. These different methods of practice, he adds merit an atten- 180 DISLOCATION OF THE ELBOW. tive comparison, that it may be decided on which side the su- periority lies. I hope the question is easily decided ; when tlie surgeon pulls the arm at a right angle Avith the body, and at the same time pushes back the lower angle of the scapula, he brings the bones into that position Avhich relaxes the re- maining connexions of the joint, and relieves the check Avhich impeded the reduction. The truth is, I believe, that Ave cannot throAv back the acromion, but in as much as Ave can Ave prevent the reduction in difficult cases, unless we at the same time elevate the arm bone. From considering the position of the head of the humerus, and effect of the ligament; and the position of thetAvo great processes of the scapula, it appears to me, that the motion to be employed completely to relax the ligament, and move the head of the humerus over the brim of the glenoid cavity, is this, let the arm be extended until the head of the humerus is felt to be draAvn from the holloav of the axilla ; the arm is then to be raised and moved in a circular direction towards the side of the patient's face. In this movement the neck of the humerus first bears on the acromion, and then on the cora- coid process of the scapula; against the last process the lesser tubercle of the humerus bears so, that with the lever power of the humerus its articulating head is raised over the edge of the glenoid cavity, and slips into its place. DISLOCATION OF THE ELBOAV. The dislocation of the ulna from its connexion Avith the loAver end of the humerus happens in young people chiefly, in AArhom the coronoid process of the ulna is not so complete a guard to the joint as it becomes in the adult. A person who running idils on his hands and Avrist may dislocate the ulna, because the Avhole Aveight and shock is received on the elboAV joint, in the line of the ulna ; and in this direction the coro- noid process is the sole guard against dislocation. The ulna >tarts backAvard, and the olecranon and articulating part of the ulna is thrown out behind the arm bone. The pronrU DISLOCATION OF THE ELBOAV. 181 Hence of the olecranon behind the joint, and the painful rigid- ity of the arm, sufficiently distinguish the nature of the acci- dent. I need scarcely add, that so firm is the union of the radius with the ulna, that both bones are dislocated when the ulna is felt thus out of place. To reduce the dislocation of the ulna, the surgeon bends the arm; he puts a handkerchief round the patient's arm, and gives it to an assistant to hold, A\ho stands behind ; then with the. left hand he takes hold of the arm, and with the palm of the right hand on the olecranon, he endeavours, by pushing, to restore the bone to its place. An assistant may facilitate the reduction by taking hold and pulling by the wrist, and gently bending the arm at the same time. However, this will not always do, and a coarser and more dangerous means has been used. The surgeon has been forced to grasp the arm Avith one hand, and the Avrist Avith another, and then thrust, his knee into the fore part of the elbow joint; and by this means bend the joint and reduce the dislocation. It will be observed, that the difficulty of reduc- tion proceeds from the coronoid process of the ulna checking into the posterior fo=?a of the humerus, and this operation by bending, and at the same time pulling separate the hones, is the most effectual way of reducing the dislocation. It Avould, however, be a very terrible accident during this operation, to find that Ave had separated the apophysis, AAhich may cer- tainly happen in a child ! SUBLUXATION OF THE ELBOAV JOINT. The subluxation of the elbow joint is when the segmoid cavity of the ulna is forced laterally, and passes over the pro- minent part of the trochlea of the humerus; the articulating surface of the ulna sits in that part of the humerus appropri- ated to the head of the radius. The nature of the accident is ascertained by the circum- stance of the great increase of the space betwixt the inner con- JL82 DISLOCATION OF THE WRIST. dyle of the humerus and the prominence of the olecranon ; the motion of the joint is impeded. To reduce this subluxation the fore arm must be extended and drawn ; Avhile it is kept stretched, the surgeon uses lateral pressure, by putting the thumb strongly over the inner con- dyle of the humerus, and grasping the head of the radius Avith the fingers of the same hand. DISLOCATION OF THE HEAD OF THE RADIUS AT THE ELBOAV JOINT. Dislocation of the lesser head of the radius is a conse- quence of a violent and sudden twist given to the wrist. It is accompanied Avith a diastasis of the bones of the fore arm. The distinguishing marks of this dislocation are, that the fore arm cannot be bent, and the rotation of the Avrist is pain- full The reason Avhy the elbow joint cannot be bent, is be^. cause the small head of the radius has burst from the coronary ligament and capsule, and noAv stands prominent forwards, so that Avhen the fore arm is bent upon the arm, the head of the radius strikes against the fore part of the humerus. To reduce this dislocation Ave pull upon the Avrist, and di- rect the hand so as to make the force bear more on the radius than on the ulna; at the same time, by twisting the hand to pronation Ave pull the radius still more. Whilst this is doing by grasping the upper part of the fore arm as if to crush the bones together, Ave endeavour to force the radius into its place. We Ioioav Avhen the reduction takes place by the flexion of the arm being no longer impeded. When the dislocation is re- duced, as the action of the muscles has no tendency to retain it in its place, it will be necessary to use a bandage, to bind the fore arm, and to keep the arm in a bent position. DISLOCATION OF THE AVRIST. The os scaphoides and the lunare forming a pretty regular ball are sometimes dislocated from the articulating surface of DISLOCATION OF THE THUMB, AND FINGERS. 183 the radius, viz. the scaphoid cavity. This may happen in consequence of the wrist being tAvisted; but still oftener from endeavouring in a fall to support one's self on the palms of the hands; by the shock the carpal bones are driven past the head of the radius. To reduce this dislocation let an assistant interweave his fingers with those of the patient and pull; the surgeon Avith- holds the loAver part of the fore arm Avith his left hand, Avith the right moves the patient's hand, and occasionally adds his strength to the effort of the assistant. DISLOCATION OF THE BONES OF THE HAND. As the bones of the Avrist are of a Avedge form, and in their union constitute an arch; the central bones are, by la- teral pressure on this arch, liable to be forced from their .place. By a bruise of the Avrist then, Ave may have one of the carpal bones luxated and standing prominent. Let not the prominence formed by the thickening of the periosteum and ligament in consequence of a Avrench, or bloAv on the back of the hand or Avrist, be mistaken for this dislocation. When the bone is displaced, it may be reduced by pressure. I have been told of bone-setters Avho could strike them into their places Avith a blow of the hand. OF THE DISLOCATION OF THE THUMB, AND FINGERS. To the young surgeon it is most unsatisfactory to be told merely, that when the fingers or thumb are dislocated, they Lie to be reduced and bandaged; while he finds that by using all his force he cannot reduce them. That such gene- ral expressions shall usurp the place of precise and intelligi- ble rules of practice is much to be regretted, since it often happens that a patient returns even from eminent surgeons with his thumbs still dislocated; and the thumb has been absolutely torn off at the second joint in the attempt to re- duce the dislocation of the fir=t! 184 DISLOCATION OF THE THUMB. From the same cause there is a difficulty to be encountered in the reduction of the thumb, and of the fingers! But the bones of the thumb being shorter and thicker, and the liga- ments of the joints stronger, it is only in the dislocation of the thumb that Ave have remarkable examples of the inef- fectual violence used in the attempt at reduction. To REDUCE A DISLOCATION OF A FINGER, AVe must not pull directly on the end of the finger; for that will be found to fix the bones by their oavh ligaments, so that they cannot come into their place. It is by grasping the finger forcibly, and bending it, that we shall succeed in bringing the heads of the bones into their natural relations. Thus far I speak from experience, but as to the disloca- tion of the thumb I must reason from the anatomy, for it has not been my fortune to reduce a dislocated thumb. We find, that in the attempt to reduce the first joint of the thumb, the second phalanx has been torn off; this should, conyince us that the difficulty proceeds from the ligaments; for the muscles of the thumb could not bear such a degree of violence. When Ave have recourse to the anatomy Ave find, that the bones are united by a proper hinge joint; that there are strong lateral ligaments ; and that the articulating heads of the bones are square, and have someAvhat of a Avedge form. Mr. Hey, taking these circumstances into con- sideration, has been led to the conclusion, that the difficulty of reduction proceeds from the head of the bone being push- ed between the ligaments, in AA'hich situation the ligaments bind the bones together, and retain them locked. I should have expected that Mr. Hey would have folloAved up these observations with the rule of practice, viz. that Ave must bend the thumb at the dislocated joint, so as to carry the head of the bone Avhich is dislocated in a semicircular movement round the articulating head of the metacarpal bone, before Ave can expect it to be brought through the two lateral liganienK DISLOCATION OF THE THUMB. 185 I shall suppose that A is the metacarpal bone of the thumb; B is the first bone of the thumb dislocated from the metacarpal bone; and C is the lateral ligament. Now let us suppose that the hitch is put over the thumb at B, and that it is drawn in the direction of the line D D. It must fol- low, that the point E will rise to D, and the heads of the bones be consequently locked at F. To reduce the dislocation Avithout lacerating the lateral ligament, it is evident that the dislocated head of the bone must be moved in the circular dotted line, which is the ex- act reverse of its motion Avhen dislocated. I have a conviction, though I cannot give the proof, that by attending to the principle laid doAvn here, the dislocat- ed thumb may ahvays be reduced. But should it be oth- erAvays, should a case occur Avhere many ineffectual endea- vours have been made, and the patient resists all further vi- olence, so thoroughly am I convinced that the difficulty proceeds from the lateral ligaments embracing the head of the bone, that I would insinuate the couching needle under the skin (obliquely), and cut one of the lateral ligaments, AAhen I think there would occur no further difficulty in re- ducing the bone. After this the joint Avould require to be supported by a small splint and bandage. This is a mere opinion,—a proposition to stand contrasted Avith the alterna- tive of the thumb remaining unreduced and lame. VOL. II. A 2 m DISLOCATION" OF TJTE LOWER JAW. DISLOCATION OF THE LOWER JAAV. If Avhen the mouth is open a man receives a blow on the chin, the jaAV may be dislocated. The jaw being in this case dropt to its utmost limit, the angle of the jaw becomes the fulchrum, and the blow on the chin forces the condyloid process forward from its seat in the articulating holloAv of the temporal bone ; it starts over the root of the zygomatic process. One or both condyles may be dislocated. The marks of the dislocation are these :—1. The mouth is open, and the teeth do not correspond. 2. On putting the finger on the root of the zygomatic process before the ear, and making the patient attempt to move the jaw, if the bone be in its place Ave ought to feel the prominence of the con- dyle of the jaAV ; but if dislocation has taken place there is a holloAv before the ear. The coronoid process of the lower jaAV is felt prominent in the cheek Avhen the bone is dislocat- ed. 3. The jaAV is protruded forward, or is distorted. 4. Saliva flows from the mouth ; the speech and deglutition are someAvhat impeded. When one condyle only is dislocated it is knoAvn by the de- pression being felt before the ear of one side only, and by the lateral position of the chin. DISLOCATION OF THE OS HYOIDES. 187 In reducing the dislocation of the loAver jaAV we must pro- vide a protection to the thumbs, by Avrapping a bit of linen round them, or by Avearing a strong glove. The patient is seated low, and his head is held firmly by an assistant. The surgeon puts his thumbs deep into the mouth, so that they rest upon the grinding teeth, the fingers grasp the chin and base of the jaAV. The back part of the jaAV is to be forced doAvnward by the strength of the thumbs, while the chin is lifted by the palm and fingers. By this exertion the surgeon endeavours to carry the condyle under the level of the root of the zygo- matic process; which stands an eminence before the articulat- ing surface of the temporal bone ; Avhich protected the jaAV from dislocation when in its natural situation; and Avhich noAv prevents its reduction. As soon as the condyles of the loAver jaw are freed from the eminence of the temporal bone, the muscles of the jaw draw them into their places, and some- times Avith so much spasmodic force as to close the teeth and bruise the surgeon's thumbs ; to avoid Avhich, he slips them off the grinding teeth upon the gums and cheek. If the surgeon does not succeed in reducing the jaAV by at * tempting to push both condyles into their place at once, he then attempts to reduce first one side, and then the other. To preserve the jaAV in its place it is only necessary to put some check upon the opening of the jaw further than is neces- sary to eating and speaking. DISLOCATION OF THE HORN OF THE OS HYOIDES. The dislocation of the horn of the os hyoides is a conse- quence of swalloAving a large morsel. The nature of this case Avas discovered by Valsalva. It is attended with a sud- den difficulty of swalloAving, Avith an uneasy sensation Avhich excites the muscles of deglutition into frequent action. There is a painful prominence of the bone, to the feeling like a tu- mour on the throat. * I have not seen this kind of dislocation. The manner of replacing it is by pressing and molding the parts on the out- 188 DISLOCATION OF THE RIB; OF THE TELVIS. side of the throat Avith the fingers of one hand, while the fore- finger of the other hand is put into the mouth, and as far as possible over the root of the tongue, so that the tongue, and consequently the body of the os hyoides, may be pressed for- Avard. I am at some loss, however, to understand how a bandage can be applied here so as to keep the bones in their due rela- tion. DISLOCATION OF THE CARTILAGE OF THE RIB FROM THE STERNUM. A young man playing the dumb bells, and throwing his arms behind him, feels something give Avay on the chest; and one of the cartilages of the ribs has started and stands promi- nent. To reduce it we make the patient draw a full inspira- tion, and with the fingers knead the projecting cartilage into its place. We apply a compress and bandage: but the luxa- tion is with difficulty retained. OF THE DISLOCATION, OR DIASTASIS, OF THE BONES OF THE PELVIS. In the many dissections which I haA'e made of women Avho have died in delivery, I have not seen one instance of sponta* neous separation, or loosening of the bones of the pelvis.— Though I have dissected three Avomen who have died, I may say of distorted pelvis, (since the difficulty of the birth from the narrowness of the pelvis was the cause of death,) and, though after opening the Avomb I have with great dif- ficulty pulled the head of the compressed child from the bones of the mother, yet I have not found the joining of the ossa pubis loosened or relaxed. If there had been any provi- sion in nature in the dilatability of the bones of the pelvis for the easy birth of the child, surely it must have been appa- rent in the only case Avhich could require such a provision, viz. where the pelvis is distorted, and the diameters dimi- nished. DISLOCATION OF THE PELVIS. 189 When the symphysis pubis separates in pregnant women, a Aveakness and pain of the loins are remarkable symptoms previous to labour; and after delivery there is an inability of moving, or standing, all a\ hich indicate disease, and not a na- tural provision for easy labour. I believe then, that the se- paration of the bones of the pelvis may be considered as a spontaneous, but not a natural loosening of the bones; and that the force of labour succeeding to this looseness of the joinings actually burst them up. When the bones of thfc pubes separate in labour, the symptoms are, (besides Avhat I have already mentioned,) a jarring of the bones felt during delivery ;# pain and fever succeeding the delivery; Avhen the Avoman attempts to rise she cannot stand, or even sit for any considerable time; hec- tic fever succeeds, and she is for a long time bed-ridden. If the separation of the ossa pubis has been considerable, then the posterior symphysis of the pelvis also suffers; and if the disposition to disease be great, suppuration may take place, both behind the pubis, so as to be discharged from the vagi- na, and on the hip from the sacro iliac symphysis. When there has been much suppuration, it is possible that the bones may at last unite, and anchylose by a medium of bone. By neglect, if I mistake not, in cases Avhere there is less tendency to caries, this species of subluxation produces a moveable joint where there should be a symphysis, or firm union by cartilage. I have not attended a case of diastasis, or separation of the bones of the pelvis; but I have ascertained, by dissec- tion, the effects of the spraining of the joinings of the pelvis. I found an abscess within the pelvis; the ilium and sacrum were disjoined, and the cartilage Avas Avasted, and the liga- ments destroyed, and the bones extensively carious. Such was found to be the consequence of the operation of the sectio symphysis pubis Avhen that horrid operation was per- petrated in France. * Pee TVnman, vol. i. p. 24-. 190 DISLOCATION OF THE OS COCCYGIS ; OF THE HIP JOINT.. The surgical treatment of the diastasis of the bones of the pelvis, I am afraid must be confined to the binding together the circle of the bones; for external applications, though re- commended on the best authority, cannot avail nor reach the seat of disease. A broad bandage of leather softly quilted, and made to draw Avith buckles, ought to be put round be- twixt the spine of the ilium and the head of the thigh bone. This Avill prevent the jarring of the bones, and allay the ir- ritation. We knoAv how incessantly the pelvis rolls on the thigh bone, and Ave know how this motion keeps up, and fos- ters the inflammation in the hip joint. So in the present in- stance, the perfect circle of the pelvis being interrupted, and the junctures loose, every change of posture causes a motion of the bones, and continues the injury. Should there be a diseased joint thus formed, either in the anterior or the posterior symphysis of the pelvis, I see no treatment more likely to effect a cure than the counter irrita- tion by issues. DISLOCATION OF THE OS COCCYGIS. By a kick, or fall, the os coccygis may be dislocated. The injury to the parts from the violence rather than the Avrong position of the bone, occasions retention of urine, or tenesmus, or even abscess, near the rectum. To reduce this bone the finger of one hand is introduced into the rectum, while by tlie co-operation of the fingers of the other hand on the outside, the dislocated bone is brought into its place: no bandage will be required to keep this bone in its natural situation. DISLOCATION OF THE HIP JOINT. The dislocation of the thigh bone from the acetabulum of the os innominatum is a most serious accident; as, besides the dread naturally arising from the application of a force equal to the bursting up of this strong joint, we have to fear the DISLOCATION OF THE THIGH BONE 191 Avasting of the bones, or a partial destruction of the joint, and permanent lameness. Yet these consequent effects are apt to foUoAv only Avhere, besides the dislocation, the internal part of the joint has been bruised, or there is a tendency to scrophu- lous action in the system. OF DISLOCATION AVHERE THE HEAD OF THE THIGH BONE LIES ON THE BACK OF THE ILIUM. The dislocation of the thigh bone upwards is marked by the shortness and strained position of the limb. It is dis- torted ; the knee and toes are turned inward, and the thigh is bent. When Ave turn the patient on his belly, and bend- ing the leg, take hold of the heel, move the leg, (like a le- ver), laterally, and at the same time put the hand upon the trochanter, Ave feel that the motion is interrupted and check- ed, and particularly that when the heel is rapidly moved inward, that the head of the thigh bone strikes against the back of the ilium, so that the motion of the thigh bone on its own axis is much limited. The attempt to stretch the limb is not successful without much force, and is very pain- ful. The head of the thigh bone may be felt as well as the trochanter, both lying on the ilium. There is pain in the groin, and a bent position of the thigh to relieve the pain and tension. The position of the parts considered anatomically is this: the head of the thigh bone having been started from its socket lies on the back of the ilium; the articulating head of the luxated bone is towards the sacro-sciatic notch; the trochanter is more forAvard, and rests upon the ilium also; the capsular ligament, and the round central ligament of the hip joint, are torn; the head of the thigh bone has torn up the cellular membrane under the gluteus raediu«, and lies under that muscle. 195 DISLOCATION OF 1HL THIGH BONE. A, the back of the ilium ; B, the thyroid hole ; C, the aceta- bulumlcft empty ; D>, the head of'the femur ; E, the trochanter major ; F, the shaft of the thigh bone. The limb operating like a long lever is here also the cause ii dislocation. When a man is pushed doAvn on his side, and the haunch strikes the ground; when carrying a heavy "burthen he falls down with the leg and thigh obliquely under him ; or, when, in riding, the horse falls on his side, and the rider's thigh is under the horse, the ligaments of the hip joint may be burst up, and the thigh bone dislocated. I haA^ found a man Avho had been buried under a bank of earth Avith his thigh bone thus dislocated upAvards and outwards; though most frequently I am inclined to believe the head of the thigh bone will be dislocated doAvnward, if displaced at all in these circumstances. Manner of reducing the thigh bone when dislocated upwards. If in an hospital, the patient is to be laid on a strong table, which is screwed to the floor; folded blankets are to be placed under him ; a soft compress is put in the perineum ; if the right thigh bone be dislocated then the patient is to be on his left side, or so that he may rest on the left hip, and that we Dislocation of the thigh bone. 193 may feel and observe the position of the dislocated bone. A 6heet is to be folded so that it may be laid upon the peri- neum, and its ends tied firmly to the table. A quilted strap is to be laid betwixt the spinous process of the os ilium and the head of the thigh bone, and the ends of this are to be fixed to the sheet. The strong leather band with hooks, (Avhich are to be found in the shops for this purpose,) are to be placed above Ihe knee that they may take hold of the thigh bone above the condyles*. But Ave may have to reduce the dislocated thigh bone Avhen we have no hospital apparatus, and therefore Ave must think of our means when in a private chamber. We first fix the bed, then Avrap around the bed post a sheet or blanket. The patient being laid on the bed with his thighs on each side of the post, he is then to lie doAvn inclined towards the op- posite side from that Avhich is to suffer the operation. In this position when the pull is made on the dislocated thigh the tu- ber ischii and perineum are made to press against the bed post. The patient's body is to be kept doAvn in this position by an assistant. It is the duty of this assistant at the same time to observe that the pelvis and trunk do not move upon the sound hip joint; for which purpose he has to lay himself on the bed, and keep hold upon the spine of the patient's ilium. The laques or hitches, may be made of hand-towels, and placed above the knee, so that they take hold of the condyles of the thigh bone. The knee is to be bent, and the leg and foot used as a lever to move the head of the bone in a rotatory manner. It is said, that when one of the towels is brought on the inside of the knee this rotation is impeded. I do not remember to have experienced any difficulty in reducing a dislocated thigh in this manner, though it had continued un- reduced for three weeks. At the same time, if Ave consider the direction of the force to be employed, and the position of * In cases of dislocation where much force is to be used, a few turns of ■» flannel roller should be put round the limb before fixing this apparatus. VOL. IT * 2 i94 DISLOCATION OF THE THIGH BONE. the thigh bone, there can be no objection to the laques being brought to the outside of the knee only. Whilst strong men pull the thigh by the laques in the line of the body, and an assistant holds the knee and ancle to give the rotatory motion, the surgeon should be placed with his hand on the joint; he may press doAvn the trochanter, but he Avill do little good or harm by his efforts there: he cannot press the trochanter doAvn Avithout at the same time pressing it to the back of the ilium, a\ hich must have the effect of de- laying the reduction. Sufficient elongation of the thigh I believe to be all that is absolutely necessary to reduction, but the elevation of the head of the thigh bone over the brim of the acetabulum will be much facilitated by the rotation of the thigh, especially by a pretty forcible jirk of the heel outward Avhen the head of the thigh bone is brought to the level of the margin of the acetabulum. No cunning exertion on the part of the surgeon is required in this stage of the operation ; the head of the bone goes with an audible snap into the socket; the perfect relief satisfies the patient that the bone is reduced. He is inclined to take as little freedom in motion after reduction as can be required by the most cautious surgeon. Unless the acetabulum is broken or diseased, there is no fear of the thigh bone again escaping from the socket. OF THE DISLOCATION OF THE THIGH BONE DOWNAVARD. The thigh bone is sometimes dislocated doAvnward and fonvard, so that the head of the bone rests in the thyroid hole, or rather on the obturator ligament and muscle. I con- ceive this to be a kind of dislocation less frequent than the last, though I see observations contradicting this opinion. It will be recollected, that the loAver margin of the aceta* bulum is eked out by a ligament, but nevertheless that this part of the socket is not so Avell calculated to restrain the head of the thigh bone as the upper part of the circle. The dis- location downwards, therefore, would often happen were the DISLOCATION OF THE THIGH BON*E. 190 force as likely to be applied so as to displace the bone doAvn- wards as to dislocate it upward. When there is a resistance Ioav on the hip, and the trunk is forcibly tAvisted over to the same side, the thigh bone may be dislocated dowmvard and forAvard : or, Avhen a man is crushed doAvn by a weight on the hip, or when the foot slips from un- der him, so that the perineum touches the ground, the head of the thigh bone may be dislocated in this direction, viz. downward and forAvard. If the head of tlie bone is displac- ed by its slipping over the loAver margin of the acetabulum, it must fall a little fonvards and lodge on the thyroid hole. There can be no difficulty in distinguishing this kind of dislocation from all other accidents to Avhich the hip joint is liable ; the thigh is lengthened, and the knee and toe turned outward; the limb straddl s, and is Avith difficulty and pain brought U> the line of the body. We have the explanation of all these circumstances in this sketch of the position of the thigh bone upon the ilium. A, the hollow of the os ilii; B, the acetabulum left empty; C, the thyroid foramen ; D, the head of the femur, dislocated and resting in the thyroid hole. 196 REDUCTION OF THE JfHlGH BONE. OF THE REDUCTION OF THE THIGH BONE WHEN DISLOCATE^ DOAVNWARD. The reader might imagine, that as the limb is already too long there can be no necessity for applying an apparatus, to stretch it as in the last instance ; nevertheless, the position, the manner of securing the patient and of applying the laques to the limb, may be the same in this case as in the last; that is, on the idea that the limb must be somewhat further stretch- ed before it can be reduced. But it requires to be particu- larly noticed, that in this instance of dislocation of the thigh bone doAvnward, the head of the bone must be lifted from the place in Avhich it is lodged, and raised to the level of the aceta- bulum before it cau be reinstated in the socket. It might at first appear, that by using the thigh bone as a lever, the ramus ischii being the fulcrum, it would be possible to raise the head of the bone from the thyroid hole by pressing the thigh backAvard and inward. But Avhen we consider the po- sition of the knee and toes, it is evident that the great tro- chanter is carried so far doAATiAvard, that by this motion it would be carried under the ramus of the ischium, and that consequently, the reduction Avould be checked and impeded. A fulcrum, or fixed point, must therefore be supplied to enable us to operate Avith effect in this position of the limb and trunk. For this purpose a large toAvel or table cloth is put round the thigh, and carried as near the perineum as may be. The ends of this cloth are to be held up by strong assistants. While the tliigh is gently draAvn so as to extend it, the cloth is at the same time raised and carried a little backward, so that the head of the thigh bone may be lifted from the de- pression in Avhich it lies. The tliigh is then bent (by carry- ing the knee forward) and drawn in that direction ; our last resource is to carry the knee to the ground, that is, towards the other side of the patient's body. In this operation avl make the cloth Avhich is put under the upper part of the thigh, a stay, or fulcrum, and by using the thigh as a lever REDUCTION OF THE THIGH BONE. 197 we unfix and raise the head of the bone. We may during this operation, roll the thigh by taking hold of the knee and ancle as heretofore described. We may perhaps find reason to prefer the folloAving method of reducing the thigh bone when dislocated doAvmvard. Tlie patient is set upright on his breech, his thighs on each side of a strong pillar ; or he may be seated on the corner of a bed, the bed-post betAvixt his thighs; something soft is Avrapt round the post, and a person is placed behind him to prevent him from reclining backAvard, and to keep him to the seat. The extension of the thigh is accomplished by drawing it at right angles Avith the trunk. My reader will readily un- derstand that by this operation the head of the thigh bone is draAvn out of the IioIIoav in Avhich it lies, and lifted as it Avere into its proper socket. If drawing in this direction simply does not succeed, then the cloth is at the same time to be put round the thigh as before, so as to draAv the head of the tliigh bone outAvard, while the knees are brought together. There is mention made of a kind of dislocation which, when looking on the subject, I should say is little likely to happenr-the dislocation of the thigh bone upward, Avhile the articulating head is forAvard on the ilium, and the trochanter backward; it will be characterised by the union of the two most distinguishing signs of the other kinds of dislocation, viz. the shortening of the limb Avhile the knee and toes are turned outward. When the thigh bone is reduced there is little fear of its starting again from its place; all that is done on this account is to put some slight binding around the thighs to check their motion. What is to be feared is inflammation in the joint, and gradual wasting of the head of the thigh bone, of Avhich I have lately seen a case. This I must suppose OAving to some badness of constitution. I Avould treat it as the con- secutive dislocation, viz. where the head of the thigh is dis placed in consequence of diseased action filling up the acf la- bulun}. 198 INJURY OF THE KNEE J01V1. DISLOCATION OF THE PATELLA. The dislocation of the patella, or knee-pan, is not an un- frequent accident. A man falling, so that the outside of the patella is struck Avhile the muscles of the patella are not firmly braced, and the limb is nearly extended, suffers this dislocation. From the nature of the accident I have de- scribed, it is implied that the bone is dislocated inward. It is most frequently displaced inward, OAving to the lesser de- gree of elevation of the inner condyle ; but it is also driven to the outside of the knee joint sometimes. This dislocation of the patella is easily ascertained, and the reduction is not difficult. The leg is to be extended, and the thumbs applied to the bone, while the fingers grasp the knee joint. If a difficulty occur it is OAving to the liga- ment of the patella preventing that bone from surmounting the condyle. In this case, as it is impossible to stretch the ligamentous connexion of the patella with the tibia, so Ave must have recourse to the further relaxation of the muscles inserted into the patella, and press the patella downward be- fore Ave attempt to carry it to its place betAvixt the condyles. A laced cap for the knee is to be used after the reduction, to hold the patella in its proper place of lodgment. OF THE INJURY OF THE INNER LATERAL LIGAMENT OF THE KNEE JOINT. This is an accident Avhich I do not see noticed. I have seen it in various degrees, and have had an opportunity of ascertaining the state of the parts in dissection. STRAIN OF THE KNEE JOIST. 199 The internal lateral ligament of the knee joint must suffer in a particular manner whenever there is a stress and unusual force upon the joint from a shock perpendicular to the limb. In this plate, A, is the thigh bone ; B, the tibia ; C, the inner lateral ligament. The force of the trunk bearing on the head of the thigh bone in the direction of the dotted line, must injure, or entirely burst up the ligament at C. So it happens, that a person descending a stair, and think- ing that he has come to the landing-place Avhen one step is still to take, falls Avith the av eight of the body bearing on this ligament, and sprains it. Hoav this is most apt to hap- pen to Avomen is evident, considering the greater Avidth of their pelvis, and peculiar obliquity of their thigh bone. For the more removed the thigh bone is from the perpendi- cular, the more apt is the inner ligament to be sprained. If the violence be great, we can readily conceive hoAV the ligament is actually torn, so as to produce A SUBLUXATION OF THE KNEE JOINT. If this accident should occur, Avhich I confess I have not seen, there can be no impediment to reduction. When ro- 300 SPRAIN OF THE KNEE JOINT* duced, our attention should be chiefly directed to restrain the rising inflammation, and to sustain the limb in its natural position by a splint and bandage. But I am bound to direct my readers' attention more par- ticularly to what I have seen and practised. When the inner lateral ligament is partially lacerated, or even strained only, there comes upon the part, slowly, inflammation and relaxation. The patient feels great pain in walking; the knee gradually falls inward, with increasing lameness. The yielding of the ligament on the inside of the knee joint being attended Avith increased obliquity of the thigh bone, the chance of further injury increases, until at every step the weight of the body bears on the relaxed and inflamed liga- ment. On dissection I have found the cellular substance and late- ral ligament, and capsule, on the inside of the knee much thickened. While they were thickened the ligamentous sub- stance Avas at the same time extended, so that there Avas not sufficient guard to the joint on this side. We understand that this thickening and inflamed state of the ligament, being a change of texture and constitution, it is followed by increasing weakness as an inevitable consequence of diminished density. The method of Cure therefore, will be in the first place to guard against all repetition of the inju- ry, and to change this chronic inflammation. The first of these requires the application of a splint along the outside, of the knee, with such a bandage around the lower part of the thigh and the upper part of the tibia, as may support the joint while there is no pressure made on the injured part. When the stiff splint has been used for a time ; motion may be al- lowed to the knee by a jointed splint applied like the former, which, Avhile it prevents the yielding of the knee joint inward ly, allows the natural flexion. The second part of the design is accomplished by applying successive blisters to the inside of tlie knee. I ought, perhaps, to have mentioned under the head of fractures, that if the knee joint of a boy be twisted violently DISLOCATION OF THE ANCLE JOINT. 201 in machinery, the apophysis of the bones may be separated. I lately examined a case Avhere a young man being caught in the spokes of a carriage by the leg while riding behind, had the lower end of the femur separated by diastasis. DISLOCATION OF THE ANCLE JOINT. I have already explained the nature of the compound dis- location of the ancle joint, Avhere the lower head of the tibia has burst the deltoid ligament which protects the inner an- cle, and the fibula is broken a little above the external ma- leolus. I have only at present to make some remarks on the degrees of injury to the joint. 1. As in the instance just now stated of the injury of the lateral ligament of the knee joint, we have to notice the con- sequences of the lesser and partial sprains of the inner liga- ments of the ancle joint. If, in stepping on an unequal pave- ment, the ball of the great toe be not supported so as to make a balance to the external position of the heel, the foot is twist- ed, and the inner ligament of the joint is injured, and al- though not ruptured, it inflames and becomes weak. 2. I am often asked by my younger pupils Avhat is to be done when the lower head of the tibia is actually forced from the astragalus, and the joint is laid open. Undoubtedly the practice is still to save the foot, and not to amputate. We replace the bones, and bind them, trusting that by bleeding and cold we can keep down the inflammation. No doubt circumstances of the patient's constitution and situation will qualify the rule. 3. A patient of a bad habit, and in a London hospital, will be doomed to suffer amputation, when in other circumstances he might be saved. We must too in all such cases take into consideration the degree of contusion Avhich the part has suf- fered. 4. If a man in leaping from a gig shall lacerate the ancle joint, the foot may be saved. vol. ji. c 2 202 DISLOCATION OF THE ANCLE JOINT, 5. If the wheel has passed over the joint, so as to displace the bones and open the joint, though in exactly the same degree, amputation will be necessary, from the general contu- sion of the parts. I state the circumstances thus to prevent my reader from imagining that in any such case he is to trust to an absolute rule or aphorism, for with the same degree of laceration in the joint, the degree of injury may be greatly varied. The ancle joint may be dislocated by the tibia and fibula slipping before the astragalus. It will be ascertained by the great projection of the heel. It is to be reduced by applying the laques so as to catch upon the heel, and at the same time to pull on the fore part of the foot, by Avhich means the toes are pointed, and the gastrocnemius relaxed. In closing my observations on the injuries of the bones and joints it becomes a duty to remind the young surgeon of the great advantage to be derived from the general healthy state of the body in the final cure of local injuries of these parts; that is, of good air most especially, of better diet than that to AArhich the patient has been accustomed* ; even of exercise, if it can be allowed in the circumstances of the case. It be- comes him to observe too, if there be any scrophulous tenden- cy in his patient, and to endeavour to counteract it; for inju- ry of the bones and joints is apt to rouse scrophulous action if there be the slightest tendency to it. We are informed that the bones of scrophulous people contain a smaller portion of earth than when the part has its healthy constitution. I would not be understood to say, hoAvever, that on this account they are more susceptible of diseased action, though they cer- tainly are more liable to disease ; they are more liable to be fractured and the ligaments of the joint having a tendency to * Even although the patient has been nursed in luxury and great abun. dance it is possible to ameliorate his condition ; though it must be confess- ed we possess more advantage when from the privations to which an hospi- tal patient has been accustomed he can be put on a more generous diet. DISLOCATION OF THE ANCLE JOINT. 203 inflame and soften, they are also more likely to be injured by sprains. For these reasons it is necessary that we should know the cha- racters of scrophula, that we should be able to recognize the disease under its symptoms,—the indolent sAvellings of the glands of the neck ; the softness of the skin, and the laxity of flesh; the largeness of the joints; the light hair and fair com- plexion, and smooth skin; the tender eye-lids and swelled lips; or the dark sooty hair, Avith cheeks of a broken ruddy colour and swelled features. If there be ulcers, either previous to the injury or in consequence of it, we find them pale, shining, and indolent, Avith little pain or inflammation. If such should chance to be the constitution of a patient who has suffered injury of the bones or joints, the cure is more precarious, and certainly more tedious; the predisposition must be Avatched and counteracted. The skin ought to be kept soft, and the vessels of the sur- face active, by the use of the warm bath and friction. The glands and glandular viscera may be kept free of the conges- tion of the indolent habit by occasional doses of calomel, and perhaps bark, iron, or acids, eventually used as giving vigour to the system. "9M of tumours: CHAPTER IX. OF TUMOURS, AND OF THE OPERATIONS TO BE PERFORMED ON THEM. Although it be my object here, consistently with my original plan, to treat only of the manner of extirpat- ing tumours, it appears to me that if I were to proceed to describe the manner of operating, without shewing the diffi- culty of discriminating the cases proper for operation, I should be in danger of doing more harm than good. The subject of tumours is involved in unusual obscurity.- There has been much done of late to draw the attention of the profession to the subject; diseases have been accurately described, and most interesting cases brought forward; yet I feel at this moment the difficulty of entering on the sub- ject without altogether deviating from modern authority. Theories have been entertained which I think defective ; au- thors have supposed they were making accurate definitions Avhen they were only framing hypotheses: and explanations of the nature of the oeconomy have been offered that to me seem quite at variance Avith the laws of the animal oecono- my. The opinions held by Mr. Abernethy and Mr; John Bell I cannot adopt, hoAArever highly I appreciate their abi- OF TUMOURS. 205 lities, and though I feel, in common with the profession, that they have done much to improve our knowledge of the sub- ject. DEFINITION OF TUMOUR. Mr. Abernethy defines tumours to be such swellings as arise from some neAv production Avhich made no part of the original composition of the body. By this definition he con- ceives that he has excluded all simple enlargements of bones, joints, glands, &c. It appears to Mr. John Bell that every tumour is a mere accretion of nutritious particles, in skin, bone, gland, or muscle, according to the nature of the part: tumour is in short, says he, either an increased nutrition, or an increased secretion, modified in its form and character by inflammation and ulceration. There has been no critical examination, surely no impor- tant objection offered to the definition of tumour, " morbo- sum voluminis augmentum," Avhich I conceive to be scientific and correct. To define Avhat is unnatural we ought to take into consideration what constitutes the natural state of the parts of the body. There is an influence governing the growth, shape, and magnitude of the body, and of the individual parts of it: the changes from infancy to age are in a series: there is an uninterrupted progression. Before the seed is put into the ground the tendency of its growth to the utmost maturity of the plant is fixed. In animals, before the first pulsation of the punctum saliens is seen in the embryo, the actions of the system AAhich lead to all the peculiarities in the mature ani- mal, are fixed also. They follow in a natural course to per- fection, in form, movement, and function. As the Avhole ani- mal is, so are the parts, governed in their groAvth ; the form of a finger is prescribed; the action of its vessels is under an in- fluence Avhich restrains the form and constitution. If the pari is cut, It unites again; not by a " stimulus of necessity," nor by a " disposition of renovation:" there is no necessity for 200 OF TVMOUKS. using this unintelligible language if Ave will but acknowledge our ignorance. What governs the constitution of the part in health unites it by adhesion, or circumscribes the neAv formed granulations when it is cut, or injured, so that they rise to the surface, but no further. There is no necessity, nay, there is no foundation for supposing, that an alteration in structure, or in the action of the part, (further than in degree,) is ne- cessary to its closing Avhen cut, to its restoration when injured. When Ave reflect that every part in its natur- al state is continually changing, not for a day remaining ac- tually the same in all its parts, but that absorption and depo- sition are going forward perpetually, while the external cha- racter and form, the internal structure and the very constitu- tion of the part remain the same, need Ave seek for any other explanation of the healing and the restitution of a part injur- ed than the continuance of the same uniform influence, the same action of vessels ? A silent and imperceptible influence preserves the part during the necessary changes from youth to age; by violence this influence becomes apparent, which is owing to the demonstrable nature of its effects, not tq tlie change of its action. We cannot judge of the action of ves- sels but by their effects; when Ave see that the tendency of increased action is to the restitution of the frame to its origin- al and perfect state, we must consider the action as natural; as still influenced by tlie same principle Avhich originally formed it, and by which, during a course of changes, it was preserved. These considerations, I hope, will lead us to adhere to the definition of tumour given by other surgical pathologists. We shall be enabled to distinguish betwixt mere tumefaction and confirmed tumour, while, I hope, we 6hall be led to a ra- tional principle of practice. A swelling is a mere consequence of over-action in vessels where yet there is no change or modification ; in this case the mere reduction of the strength and activity of the part Avill be followed by the reduction of the tumefaction. • OP TUMOURS. 207 A tumour, on the contrary, is a circumscribed swelling, Avith new modification of the structure*, which arises in con- sequence of a specific action ; does not spontaneously disap- pear ; and Avill not subside by the mere subtraction of blood, or diminution of activity in the vessels. A tumour is often superadded to the natural body, but is constituted sometimes by the preternatural augmentation of a part; for example, of a gland, in consequence of a specific change, and increased activity of the Aressels of the part. In illustration of a\ hat I have here delivered I venture to add this example: When a man breaks his leg I conceive it is healed, not by a neAv action, not by a stimulus of necessity, Avhich implies the residence of an intelligent principle, but by the continuance of that uniform influence Avhich brought it from cartilage to bone, Avhich prescribed the form of the bone, which preserved its form whilst its particles were changing daily. Those operations Ave did not see : neither the de- struction, nor the renovation of the parts; but now we see the renovation because the destruction and injury were palpable ; and this, not from the change of action, but from the change of circumstances. When, however, the new bone is not level Avith the old, when it is different in structure and redundant, * On the term rumour, the following observations of Mr. Pearson are most pertinent: "Chirurgical writers have generally enumerated tumour zs an essential symptom of the scirrhus ; and it is very true, that this dis- ease is often accompanied with an increase of bulk in the part affected. From long and careful observation I am however induced to think, that an addition to the quantity of matter, is rather an accidental, than a necessary consequence, of the presence of this peculiar affection. When the breast is the seat of a scirrhus, the altered part is hard, perhaps unequal in its figure, and definite ; but these symptoms are not always connected with an actual increase in the dimensions of the breast: on the contrary, the true scirrhus is frequenUy accompanied with a contraction, and diminution of bulk, a retraction of the nipple, and a puckered state of the skin. The irritation produced by an indurated substance lying in the breast, will very often cause a determination of blood to that organ, and a conse- quent enlargement of it; but I consider this as an inflammatory state of the surrounding parts, excited by the scirrhus acting as a remote cause, and by no means essential to the original complaint-. 208 OF TUMOURS. there is something out of course and unnatural; there is dis- ease ; the vessels have not merely received an impulse of acti- vity, but there is a new influence. If the diseased action should here build up a large protuberance, I call that exosto- sis tumour, though it be of the same blood and bone with the original part. The changes which take place in the body are not so gross and palpable as to be manifest to our senses ; Ave can see no difference often in a mild ulcer, and in one which will be pregnant with mortal contagion. If we are to take only the grosser distinctions of matter as pointing out the difference betAvixt tumour and SAvelling, we shall be in perpetual diffi- culty ; if an exostosis be no tumour because it is only the original matter, is an accumulation of flesh and bone a tu- mour ? or, is a large tumour, full of bone, and membranes, and vessels, and flesh, which groAvs amongst soft parts, to be considered as a proper tumour ? or, is it only a tumour when it contains grey matter, or something unlike what we see in the natural structure of the body ? If this last circumstance be taken as the true definition of tumour, then many circum- scribed swellings of specific action, fatal from the tendency of that action, or the peculiarity of their place, which resist all known means of cure, and absolutely require the knife, are left still to be classed. Another important consideration in practice is, that the place and tendency of the action in the tumour being ascertained, the line of practice is clear ; but if our attention be drawn to the distinctions of internal struc- ture only, to distinctions which have no corresponding out- ward sign to mark their existence in the living body, we are led from the rule of practice, and left without a guide. Surely there is great imperfection in the very first step of Mr. Abernethy's classification ; his first genus being known from the tumour being composed of the coagulable part of the blood rendered very generally vascular. This vascular coag- ulable lymph is the fore-runner of all natural changes of the parts in health and vigour. So Mr. Hey, in describing the fungus nematodes remarks, that the origin of the tumour OF TUMOURS. 209 must have been extravasated fluid become organized; and then he asks, was it blood mixed with a large proportion of lymph ? neither the microscope, nor chemical analysis of the solid or fluid contents of tumours, will ever serve to point out the character Avhich is to guide us in practice; we must take into consideration the peculiarities, constitutional and local, and as far as we are able endeavour to recognize the external character, and study the course of the disease, as the most likely to make us acquainted av ith the peculiarity and tendency of the action. In this investigation we must often recur to the dissection of the tumour, and to the in- ternal structure as our guide ; but the knoAv ledge of the in- ternal structure can be useful only as it directs our enqui- ries, or enables us to judge of the patient's danger by the nitAvard sign. I hope my reader will allow me to detain him from the ' practical part of this tract a little longer, in order that I may explain my opinion on the subject of tumours formed out of coagulated blood. Tlie observations of Mr. Hunter on this subject being, as I think, the foundation of the com- mon opinion, the folloAving excerpt may be taken as ex- planatory of it;— " In the course of his experiments and observations, insti- tuted Avith a view to establish a living principle in the blood, Mr. Hunter was naturally induced to attend to the pheno- mena which took place when that fluid Avas extravasated, whether in consequence of accidental violence, or other cir- cumstances. The first change which took place he found to be coagulation: and the coagulum thus formed, if in con- tact Avith living parts, did not produce an irritation similar to extraneous matter, nor was it absorbed and taken back in- to the constitution, but, in many instances, preserved its liv- ing principle, and became vascular, receiving branches from the neighbouring blood-vessels for its support; it afterwards underwent changes, rendering it similar to the parts to Avhich it was attached, and Avhich supplied it with nou» rishment. vol. i*. D 2 210 OF TUMOURS. " In attending to cases of this kind, he found that where a coagulum adhered to a surface, which varied its position, adapting it to the motions of some other part; the attach- ment Avas necessarily diminished by the friction, rendering it in some instances pendulous, and in others breaking it off entirely. To illustrate this by an example, I shall mention an instance which occurred in the examination of a dead bo- dy. The cavity of the abdomen Avas opened, to examine the state of its contents, and there appeared lying upon tht- peritoneum a small portion of red blood, recently coagulat- ed ; this, upon examination, was found connected to the sur- face upon Avhich it had been deposited, by an attachment half an inch long, and this neck had been formed before the coagulum had lost its red colour. Thi9 steeped in water s« as to become white, appeared like a pendulous tumour." " From this case it became easy to explain the mode in Avhich those pendulous bodies are formed that sometimes oc- cur attached to the inside of circumscribed cavities, and the principle being established, it became equally easy for Mf. Hunter to apply it under other circumstances, since it is evi- dent from a knoAvn law in the animal oeconomy, that extra- vasated blood, when rendered an organized part of the body, can assume the nature of the parts into which it is effused, and consequently the same coagulum whieh in the abdomen formed a soft tumour, when situated on a bone, or in the neighbourhood of bone, forms more commonly a hard one. The cartilages found in the knee joint, therefore, appeared to him to originate from a deposit of coagulated blood upon the end of one of the bones, which had acquired the nature of cartilage, and had afterwards been separated." Mr. Abemethy continues the subject in these words:., a had vessels shot through the slender neck, and organized the clot of hteod, observed by Mr. Hunter, it would then have become a living part, it might have grown to an indefinite magnitude, and its nature and progress would probably ^ave depended on the organization which it had assumed. I have in my possession a tumour, doubtless formed in the manner OF TUMOURS. 211 Hr. Hunter has described, which hung pendulous from the front of the peritoneum, and in Avhich the organization and: consequent actions have been so far completed, that the body of the tumour has become a lump of fat Avhilst the neck is merely of a fibrous and vascular texture. There can be little doubt, but that tumours form every Avhere in the same manner. The coagulable part of the blood being either ac- cidentally effused^ or deposited in consequence of disease, be- comes afterwards an organized and living part, by the groAvth of the adjacent vessels and nerves into it. When the depo- sited substance has its attachment by a single thread, all its vascular supply must proceed through that part; but in ether cases the vessels shoot into it irregularly at various parts of its surface. Thus an unorganized concrete becomes a liv- ing tumour, Avhich has at first no perceptible peculiarity as to its nature; though it derives a supply of nourishment from the surrounding parts, it seems to live and groAv by its oavii independent poAvers; and the future structure which it may acquire, seems to depend on the operation of its oavii vessels. When the organization of a gland becomes changed into tliat unnatural structure which is observable in tumours, it may be thought in some degree to contradict those observ- ations: but in this case the substance of the gland is the matrix in ivhich the tumour is formed." When Mr. Hunter, Mr. Abernethy, Mr. Home, Mr. Hey, and Mr. John Bell, give up their time to the investigation of the nature of tumours, it is an injunction on me to do my ut- most to satisfy my reader on the subject. Perhaps some of these gentlemen may feel contempt and indignation at the idea of controverting opinions so substantiated as these I have transcribed. But in a science so interesting, the assumption of superiority is a singular instance of inconsistency, and car- ries Avith it a most ridiculous air of folly. Whoever makes the philosophy of the living body his study may be taught humility, and fpom his oavh errors learn to look mildly on those of others. 2A.2 OF TUMOURS. I would have my reader to recollect the phenomena of the formation of bone, in cartilage, in membranes, or in that mass, Avhich Ave are accustomed to call callus, around the ends of-a broken bone ; of the formation of neAv membranes; of the adhesion of the soft parts by an intermediate sub- stance ; as Avell as of the formation of tumours from coagulum, as it is imagined. And I intreat him not to attach himself entirely to a solitary fact, nor to give himself up implicitly to the guidance even of a Hunter, who, amidst all the splen- dor of his talents, was often unintelligible. 1. I think the leading error of this doctrine is the inat- tention to the distinction betAveen the coagulum thrown out from the organized extremities, and that which is spilt as it were by the accidental rupture of a vessel. In the one in- stance it is a secretion; and in the other a mere extravasa- tion, possessed of no power of reproduction; absorbed, if in a small quantity; a source of inflammation and suppuration, If in a great quantity. I must see the coagulum of blood thrown out in apoplexy, and in aneurism, full of vessels, before yield- ing up the conviction that the coagulum of blood accidental- ly thrown out is absorbed, and a nevV deposition secreted, previous to the formation of vessels. 2. It is matter of surprize to me, how the physiologists, who support the original observation of Mr. Hunter, can adhere Avith such devotion to the circumstance of this coagu- lum forming a cpnnexion with the peritoneum obscurely ima- gined* when if the fact Avere so, viz. that coagulum of pure blood formed adhesion to that, or any other surface, and grcAv there, it Avould be as familiarly known to every surgeon, as it is demonstrable that extravasated blood is absorbed, and that a limb turgid with extravasated blood will resume its form* 3. We frequently have coagulum thrown out from inflam- ed surfaces with such a proportion of the colouring particles of the blood, as to appear like a pure coagulum of blood some- what blanched ; and I have no doubt the coagulum found by Mr. Hunter was of this nature. But while I believe that 0F TUMOURS. 2X$ the pure coagulum of blood escaped from the rupture of an artery, or a vein, has no power, of adhesion, or of forming ves- sels within it, yet if circumstances should present themselves to convince me of my error, the following view of the subject would stand uncontroverted by that circumstance. 4. Every part having a peculiarity of structure, preserve* that peculiarity by the prescribed modification in the activity of its vessels ; this modification is continued when the part is injured, or cut, and the renovated matter is consequently like tlie original substance. Violent injury will sometimes in- terrupt this natural renovation; but on the subsiding of the violent commotion, and the return of the natural action, the part is reinstated. As* however, the functions, (and we may perhaps venture to say the structure,) of some parts of the body are more delicate and peculiar, these are not restored in all their pristine perfection, though ahvays Avith such a rela- tion to it as to show that the bond of union of the divided part* is not the same in all, but holds a relation to the origin- al formation. 5. If a bone is broken, a coagulum is throAvn out; the ves- sels of the bone penetrate this coagulum, and the vessels of bone deposit bone. Such is the received explanation of the formation of new matter of bone, and a most imperfect one it is. This opinion does not at all correspond with the facts, which stand thus: The mass Avhich we call callus, and which surrounds the broken ends of bones, is supplied with vessels principally from the surrounding soft parts, and yet bone is formed. If, therefore, the source from which the vessels chance to be derived influenced their action, muscle and membrane would be formed, instead of earthy matter depo- sited. The fact, as it has appeared to my eyes, is, that the original coagulum of blood, which is by the violence of the accident, and the rupture of vessels, thrown out around tlie extremities of the bone, is absorbed, and a new deposition is slowly secreted ; the source of that secretion is the bone, and bone is formed in that nidus, although the vessels supplying it with blood be from parts entirely different in structure and 214 U4 TUMOUR^. use. The medium into which the vessels pass influence their activity, wc might say, but I belieAre this is not the entire truth;—an artery does not bore and Avork its way into a co- agulum as has been described. Some people's minds are ea- sily satisfied I and Avhen they think of the force of the circu- lation, they conceive it an evident and likely thing that the blood forces its way forward; that the arteries push out and enter this substance, without ever imagining it necessary to consider how veins, and lymphatics, and nerves make their way into this new matter. It appears to me, that this se* creted coagulum in the very act of its formation receives its character; that its structure is already determined -, that the tract of its vessels is laid; that the parts are in embryo ; when blood is received, the previous determined structure influences the secretion to be drawn from it, as in all other instances. Thus far we have been speaking of natural changes of re- novation;—tumours are unhealthy superstructures. If tu- mour forms from coagulum, that coagulum is not the mere blood escaped from the vessels, but a coagulable part secret- ed by the vessels of the surface, under a peculiar influence in their action; and according to that action is the growth of the future tumour. Its character, the matter secreted into it, and the proper substance of it, depend on the original formation; in other Avords on the influence of the vessels Avhich secreted the coagulum. The folloAving scheme of tumours, reduced under four heads, I hope will be found a suitable introduction to my observations on the manner of extirpating them. QF TUMOURS. 215 I. INCYSTED TUMOURS. (CySttdeS.) We must distinguish the term cyst from capsule, which latter I think ought to signify the condensation of the cellu- lar substance round a solid tumour. The incysted tumours consist of a cyst, the contents of Avhich are secreted by its inner surface. Hydatides. Delicate incysted tumours often gregate; and entangled in the cellular membrane. The incysted tumours containing lymph, or serum, have been called hygroma. Even here, in the first step of our inquiry, we are at a loss to mark the distinction betwixt tumours of the cellular mem- brane, and those transparent bags uniformly round and smooth, filled with clear water, and which have no adhesion, which are distinct animals: "they produce their like, and multiply." Although these animals cannot be considered as tumours, being themselves animals, yet they become a charac- ter of disease, since I imagine that there is a previous nidus for them in a change of vascular structure, or action. There is yet a third distinction under the head hydatid, more distinctly animals, the tenia hydatiginta. These I have found in the monkey, sheep, and hare. They adhere to the vascular mem? branes of the viscera, by a pendulous membranous sac, which has vessels branching on it; within this, sac the hydatid is contained quite loose. Some of diem hi the same animal 1 have seen with one mouth, some with two, and others smooth without any, which led me to doubt whether these white cor- rugated projections on the sac were indeed the mouths of the animal. I have found a worm like the tenia, and these tenia hydatiginea floating loose in the abdomen of the same animal. Ganolioh. A solitary incysted tumour, connected with ten- dons, or ligaments. .RANUUi. (See Diseases of the Mouth.) An incysted tu* mour under the tongue, or projecting on them- side of the cheek. 21b OF TUMOURS. I would place here, under the head of incysted tumours, sacs containing fluid blood, such as I have seen about the throat. Cysts containing matter dense, like these three last exam- ples, have been called lupia. Melic£ris. An incysted tumour, the matter being of the consistence of honey. \theroma. An incysted tumour, the matter contained be- ing pultaceous. Steatoma. An incysted tumour, the contents of which are fatty, or like suet. II. glandular tumours. (Phymata*). I. Scrophulous tumours. 2. Sarcoma. A tumour, to the feeling of the consistence of flesh. Under this head AAre must place a very great variety of diseased enlargement of the glands, varying in the kind of glands they attack, in their outAvard character, in the celerity of their growth, in their termination, and in the ap- pearance of their contents. There will of course fall under this head several tumours of distinct glands : aR, Bronchocele. Enlargement of the thyroid gland. Sarcocele. Fleshy tumour of the testicle, or cord- Z. Scirrhus. A hard, irregular, and indolent tumour of a gland. The knobby hardness of a tumour is, no doubt an alarming circumstance, but such indolent affections of the glands often appear in mature years, which prove unconquerable, and yet continue innocent to the latest period of life. When surgeons speak of the true and exquisite scirrhus they mean the carcinoma. ■* A tumour having its seat in a gland; " born of itself," and proceeding from no evident injury. OF TUMOURS. 21? 4. Carcinoma. A tumour of a gland, in a state of activity approaching to cancerous ulceration*. The tumour is hard and unequal ; there is a lancinating pain in it; the skin is purple, or livid red ; and the cutaneous veins are en- larged. 10° To the term Cancer Ave find the Avord6 apcrtus and ocultus joined ; the first meaning the open ulceration ; and the other, the sense I have given to Carcinoma. The spreading of varicose veins over the surface of the tumour being considered as a symp- tom of great malignity, aatis the reason of the term cancer being used ; they conceived they saAv a resemblance in the branching of the veins to the claAvs of the crab ! A true cancer, arrived at ulceration, has the edge of the ulcer serrated, indurated, retorted; the errosions betwixt the excrescences are deep, and bleed from time to time; there is constant burning pain, and the discharge is sordid, sanious, and peculiar in its fretor. Internal parts and canals having a glandular structure, though not the outward form of glands, partake of the scir- rhus and carcinoma. We have the disease in the oesophagus, in the stomach, in the rectum, &c. -5. Brr.n. A hard, phlegmonous, swelling of a lym phalic gland, from disease received through the absorbent system; or symptomatic of acute and malignant constitutional derange- ment. * When a surgeon writes that his patient is strumous, the case is unde lined ; but there are swelled glands with suspicion of scrophula. If he says, lie has scirrhus tumours about the neck, I understand, somewhat indefi- nitely, that they are hard and knobby, and suspicious in their nature ; but when he says, that they are carcinomatous, I imagine he has no doubt from the veins about them; from the hardness and lancinating pain, and inc.re«w rd inflammation, that they are cancerous, and of a fatal kind. vor. it. R 2 238 WJ TUMOURS. We are quite unable to distinguish accurately the charac- ters of the tumours of which the glands are tlie nidus. There is a very great variety of them, proceeding from the changed disposition of the vascular action. We sometimes find a solita- ry tumour about the throat, which will at last inflame, and become active and cancerous. Another case will present, where with the same character, we see that the disposition spreads, and there are many glands diseased; and on occa- sions, that the disease is not confined to the lymphatic glands, but spreads to the salivary and thyroid glands. Sometimes we see a disease commencing in the glandular structure, propagated without seeming preference to parts of the same original structure with the gland ; but in\'olving skin, cellular membrane, and even muscle and bone, in a diseased assimi- lated action. HI. VARIX. Varix is a tumour of enlarged veins. When the vessels: are distended, it is not in breadth only, but in length also ; and to accommodate themselves they must necessarily be twisted. But neither varix nor aneurism ought to be consi- dered as tumours, for there is no peculiarity of action amount- ing to disease ; it is but at most a derangement of mechanism, the mere effect of pressure. But as the derangement of the natural action always endan- gers the substitution of permanent disease, so in instances of mere distension of veins Ave find diseased action to be a conse- quence of it, as in the instance of haemorrhoids, (tumours on the verge of the anus) which* though at first a mere distension of the veins and cellular membrane by blood, or lymph, become firm fleshy tumours. (Marisca.) But it is of consequence we should particularly notice, that besides venous distension being a mere effect of the pressure of the blood; and besides, being a sign on the surface of solid tumours of virulence Avithin; that there are tumours of varicose veins, distinct altogether in character from these, and which have a history so peculiar, that I deem it right to put them under a different head altogether. See Hypersarcosh. OF TUMOURS. 219 IV. RXCRESCXNiriJF.. Folyfus. A pendulous tumour from a canal, or cavity. Cartilaginous tumours appended to the inner surface of the capsular ligaments of joints. A question still remains to be decided;— are the loose cartilages in the knee joint of the same origin Avith those attached to cartilagi- nous bodies ? If it is concluded that they are, and that they are excrescences of the natural cartilage, hoAV do Ave account for bodies of the same kind being found loose in the vaginal coat of the testicle. Veruca. A warty, cutaneous excrescence. Exostosis. The excrescence from a bone Avhere there is no • general enlargement. Nodus. The thickening of the membranes Avhich cover a bone ; it is often the same disease Avith the last. Fungus. This terra implies the soft excrescence from a surface ; as of a bone, or of the dura mater. N.«vus. (Nawus matcrnus.) A flat congenital excre- scence of the skin. Sometimes rough and Avarty ; often with hair upon it; of a purple, redish, blue, or black colour. It is only in common language that Ave can call a corn, (cla- ws,) a tumour; for it is a mere effect of pressure. There is no diseased action, but the continuation of a natural action ; an action of a kind in other circumstances to preserve the bo- dy. The accumulation of the layers of the cuticle on the palms of the hands and soles of the feet, as a consequence of use and pressure, is a happy provision for the protection of the parts beneath. But Avhen pressure is on a point, there the accumulated cuticle acquires a hardness equal to horn, and bears hard on the soft parts beneath, m OF TUMOURS* Under this head of Excrescentim there might be enumerat- ed many terms Avhich imply tumours of particular parts; as for example: Epulis. A tumour of the gums and alveoli, Pterygium, or Pterygion. A thickening of the. tunica con* , . junctiva. Encanthig. A tumour of the inner angle of the eye, in th,e« seat of the caruncula lachrymalis. Staphyloma. A tumour of the cornea, &c. V, THE DISJGASLD GROW 111 Of A VASCULAR, FLESHY SUBSTANCE, involvisc THE parts promiscuously. (Hypcrsarcosis.) Under this head I put such tumours as are of a fleshy con- sistence, and not distinctly of glandular origin, but Avhich spread equally around. * Fungus hjematodes of Mr, Hey. This disease may take its origin in muscle, cellular membrane, or even bone. Some- times it begins as a distinct tumour ; sometimes as a general enlargement of the part; as of the leg, thigh, or shoulder; generally it is not painful. It is irregularly soft, (of uneven density,) and to the feeling there is a sensation of extravasatr ed fluid, yet not of a fluid in a distinct sac. There is no ir- regular hardness; and no puckering of the skin. If it be seated under the fascia the distension has a considerable elas- ticity. The veins on tlie surface are much enlarged. In its progress the tumour bursts ; and a soft, dark coloured, bloody excrescence rises from the centre, Avhich bleeds freely, and re- duces the patient's strength. The irritation, and the haemorr- hagy together, carry him off. When this tumour is opened in the life of the patient, the bleeding is profuse. When its contents are examined after extirpation, there is a greasy, ash coloured substance in the midst of a vascular bed.

Its origin is often from those marks on children called nasi materni; but some- times, apparently from injury of the skin in the adult. The disease is, for the most part long stationary, Avhen, Avithout any apparent cause, the action of the vessels acquire vigour, the pulsation becomes perceptible, and the tumour sensibly increases. The colour of the tumour is a blackish blue or purple, and on the most prominent part there is an excre- scence like a mulberry, Avhich bleeds profusely from time to time. The substance of the tumour is cellular, and contains pure liquid blood. The blood can be pressed from it, and, to the feeling, the bags are soft and avooIIv. It destroys the. patient by hreinorrhagy, When dissected it is like a mass of placenta. This disease cannot be called an aneurism, which is a puh: ating tumour of blood, from a mere injury of the machine, from a yielding of the coats of the arteries Avithout any pe- culiar action. It is not a varix, Avhich is a mere venous dilat- ation in consequence of an impeded return of the blood. In this tumour, on the contrary, there is a specific and very pe- culiar action, and nothing resembling either the impeded cir- culation of aneurism or varix, Anomalous tumour.—Under this name, in various collec. tions, Ave have both of the last mentioned cases; but besides such as correspond AAith these of Mr. Hey and Mr. John Bell, there still remain many tumours of the bones, muscles, and 6kin, Avhich entirely differ from them, and which have had as yet no name given them. I have dissected a tumour of large size, Avhich it Avas impossible to say resembled most the steatomatous tumour, or the vascular tumour described by Mr. John Bell, and in the substance of the tumour there were many cells full of liquid blood. These cells Avere not the ir- regular cavities of varicose vessels, but of a perfectly regular form, they had a smooth secreting surface. 1 Avould have called them hydatids but for their contents. The nature of the osteo-steatomatous and osteo-sarco- matous tumour i<= but little knoAvn; the first term implies 222 st.:' i'UMOUitS. the growth of a steatomc in the marroAv of the bone, in which the bone enlarging becomes a shell to the fatty tumour, until perhaps the softer substance bursts through the bone*. Tlie term osteo-sarcomatous describes that softening and enlarge- ment of a bone in which the tumour exhibits a mixture of soft and bony matter and softer fleshy substance. But the action of the vessels, the nature of these tumours, partakes of a great variety. Indeed the term steatom gives us an im- proper idea of tlie common fatty tumour of the body, which is a diseased acretios of fat nourished by vessels, and often Avithout a cyst, or much to distinguish them from the com- mon fat hat their inordinate groAvth. It is not in vindication of the imperfection of this sketch of a classification of tumours that I venture to throw out a doubt of a possibility of making a perfect catalogue and a de- scription of them. Without boasting of how much I have seen, I may assert that I have seen a distracting multiplicity in the character of tumours. I have seen lately, and expect often to see, tumours which bear no accurate resemblance to such as I have seen before, or such as I find described. Tumours are not like animals, each proceeding from a stock, and bearing the mark of that origin. They are not like the diseases of the natural body, Avhich, in similar circumstances is always similarly affected. But, to use the Avords of Mr. Abernethy, they are edifices which are built up by diseased actions, and in Avhich these diseased actions reside. There is - In the greatest enlargement of a bone it often occurs, that what appears like an immense bone is but a shell. When the bony matter is absorbed on one side of a bone, we see it accumulated on the other; when wasting with- out, accumulated within ! in short, when there are the most decided ravages of disease the bone is strangely disfigured, but still the mass of earthy mat- ter remains nearly Uie same. Ii considering this disease of osteosteatoma, or of the cases which I have seen, when the tumour of aneurism, and the formation of bone went on together; it appears, that the bony matter forms a shell as long as the original quantity of matter is not exhausted; at last, however, the growth of the original tumour becoming too Urge, the thin shell of bone is absorbed over the most prominent part of the tumour, and :he turno-jr seems to hires* through. OP TUMOURS. 223 in this opinion much to ponder on and to admire. The mat- ter in which the action resides, is the result of disease; the disease varies in its nature; the structure of that matter, so formed, slightly deviating, must affect the action residing in it; and that action having no doubt the character of all de- viations from nature, viz. a less definite and circumscribed existence may be undoubtedly varied and modified. Thus it appears to me that neAv diseases are formed in many of the individual tumours, though they are not propagated: a cor- rect general classification may no doubt be expected from careful observation, but I think it will ever be liable to de- rangement by the observation of individual cases. OP THE TREATMENT OF TUMOURS. Of a swelled gland. It is only by the continuance and ob- stinacy of a tumour in resisting remedies, that we know it to have such a peculiarity of action, as to afford little hopes of its resolving. In the beginning of every tumour, therefore, much the same practice may be pursued \ and I shall state what is right to be done, under the idea that Ave still hope that it is merely a gland accidentally swelled; and where the diminution of the action may be folloAved by the decrease of size, and the restoration of its natural function. When a patient comes to us with a swelled lymphatic gland AA-e first consider the probabilty there is of its being in consequence of some irritation in the course of the absorb- ents ; or we attend to the probability of its being scro- phulous and constitutional. If Ave find it a solitary swelling of a lymphatic gland, for example, in the neck, we take into consideration its seat, and the course of the vessels; there is, perhaps, a scabby eruption about the roots of the hair, a gum- boil, ulcerated sore throat, discharge from the nose, &c. If there should not be one, but many glands swelled, and indu- rated, we must look to the age and constitution, and not com- mit the error of treating wholly as a local disease that which has its origin in the prevailing tendency of the system. 224 Of TUMOURS. When a gland enlarges, leeches arc to be applied, and the part frequently bathed Avith tepid water; on the second and fourth day they are to be repeated; and Avhen the bites have healed a blister is applied with the best advantage. If, Iioaa- ever, the gland shows itself to have much inflammation, a blister Avill aggravate and increase the swelling ; and even in cases Avhere the gland seems indolent, it is necessary to secure a certain degree of Aveakness in the vascular action of the part, before any thing stimulating be applied to the surface. I am very partial to the use of vomits in discussing inflamed glands. When glands enlarge from the action of cold in a scrophu- lous constitution, cold wet applications are to be.avoided ; in- deed, in that case it will be better to have recourse to warm fomentation of decoction of chamomile, and of sal ammoniac, or of salt and water, or of gentle and long-continued friction Avith the hand, or Avith stimulating oils. The part should be kept warm ; and if the above plan is found too trouble- some to be employed, in the absence of affectionate care, a warm plaster of cummin-seed may be applied. If we find that there is a concealed scrophulous action in the system, but that Avhere the skin is exposed there chiefly the glands sAvell, it is most probable that the glands are suf- fering'by sympathy Avith the skin ; which is the reason I re- commend the plan of fomentation and friction ; but when the enlargement of a gland has no such origin, avc may apply ei ther cold solution of ammonia muriata, and cerussa acetata on cloths, or the blister, without deviating from the intention of diminishing the vascular action. The general explanation of the action of a blister is, that it excites the lymphatics, and consequently assists the absorption and diminution of the tu- mour. I imagine it is to be explained thus: if the blister he applied Avhere there is a tendency to inflammatory action, the. stimulus is propagated backAvard upon the trunk of the ves- sels brought into activity ; but if the power of re-action be previously subdued, then this irritation makes a revulsion from the deep parts, by bringing the blood which would otherAvise pa*s to the deep pnrt? to supply the superficial vessel^: what- or TUMOURS. 225 ever diminishes the activity of a swelled gland restores the balance to the absorbents, which were previously overpower- ed by the activity of the arteries; for it would not be diffi- cult to prove that the lymphatics are less under occasional in- fluence than the arterial system. While we endeavour to reduce the activity of a sAvelled gland by direct means, we must prescribe purgative medi- cines twice a week, and enjoin an abstemious diet; tempe- rance is of the utmost consequence where there is danger of a eonfirmed scirrhus. If the gland continues hard after this treatment, our next resource is an alterative treatment, by giAdng small doses of calomel, or corrosive sublimate. The extract of cicuta with calomel is a favourite remedy. Elec- tricity is used, not as a counter irritation, but directly affect- ing the gland; it rouses its activity. We must be well aware of the mildness of the nature of a gland which we rouse to activity: no doubt, if there be no malignity in a gland, the rousing the vascular action may be productive of a change, and cause its final absorption ; as it is sometimes observed, that a gland having been long indolent, swells, be- comes painful, and then disappears. It is a different expectation Avhich makes the surgeon ap- ply caustic to a tumour ; he expects, that being of a mild, indolent nature, with little capacity of action in it, the life of the part, (being diseased), may be too Aveak for the violent operation of the caustic, so that the whole part may slough out. Such is the common effect of escarotics and caustics to a Avart; the life of the excrescence is weaker than that of the natural parts on which it groAvs, and consequently while the application is too severe for the diseased action, the sound parts remain unhurt. But this is a dangerous practice in regard to scirrhous tumours; instead of destroying the dis- ease, we may only rouse it to activity. When a tumour is excited to virulence by corroding, or stimulating applications, it is doubted, whether the latent ma- lignity of the disease be merely roused, or a new action be produced ; our most intelligent surgeons seem to think that VOT. IT. F 2 2S6 OF TUMOURS. there is no such thing as the conversion of disease i- Mr* Pearson expresses himself thus: " Writers have indeed said much about certain tumours changing their nature, and as- suming a neAv character: but I strongly suspect, that the doctrine of the mutation of diseases into each other, stands upon a very uncertain foundation. Improper treatment may Avithout doubt exasperate diseases, and render a ^complaint which appeared to be mild and tractable, dangerous or de- structive ; but to aggravate the symptoms, and to change the form of the disease, are things that ought not to be con- founded. I do not affirm, that a breast which has been the seat of a mammary abscess, or a gland that has been affected by scrophula, may not become cancerous; for they might have suffered from this disease, had no previous complaint existed; but these morbid alterations generate no greater pro- pensity to the cancer, than if the parts had always retained their natural condition." I cannot entirely agree with this opinion. I conceive that a part deprived of its natural ac- tion, is in a certain measure throAvn out of the governance of the general ceconomy, and is left a prey to irregular action, to disease. When a gland is* injured by a blow, and the inflammation has gone high; if the natural structure and osconomy be deranged, permanent disease follows the subsid- ing of the mere inflammation. So Ave see that there is a period of life when the breast and Avomb become useless, and the influence of the system is no longer felt upon them ; then disease fixes on them. I am not able to give any other explanation of the cancerous affections of the womb and mamma being so frequent at the turn of life. By pushing this discussion a little further I am led to conclude, that dis- ease is not the effect of circumstance, and impression, but that there is a latent tendency to certain diseases, which take place in the absence of the controul of the healthy action. Of the extirpation of tumours by the knife. Tumours of glands are cut out, as being likely to propagate a malignant disease; as apt to increase and press upon important places, as the eye, or throat; or lastly, from mere unseemliness. OP TUMOURS. 22} Before AA-e think of using the knife, we must consider Avell whether the tumour be simply scirrhous, or if it be of the nature of a carcinoma; or Avhether a capsule has been form- ed which marks the limit of the diseased action, or the sur- rounding parts be imperceptibly assimulated into the disease. In carcinoma, Mr. Hunter observed a disposition in the sur- rounding parts prior to the actual occurrence of disease in them. This remark, says Mr. Abernethy, is ratified by daily experience, and has led to the folloAving rule of practice ; that a surgeon ought not to be contented with- removing merely the indurated, or actually diseased part, but that he should take aAvay some portion of the surrounding substance. The simpler statement I fancy to be, that long before the eye can discover diseased texture in the substance, the action is pro- pagated which must necessarily precede this effect. HoAvever that may be, it is particularly necessary to exa- mine the edges of a tumour AA'hich has been cut out, and to see that there is none of the peculiar texture of the tumour terminating abruptly on the edge, as if cut through. For ex- ample, the character of carcinoma, as exhibited on dissection, is in the condensed cellular membrane, Avhich has a very pe- culiar appearance of irregular diverging streaks of a Avhiter colour, in the darker substance of the tumour ; noAv if these membranous bands have reached into the cellular texture which has been left after the tumour is cut off, the disease will inevitably return, and grow Avith a rapid progress. The tumour is, therefore, to be held in reference to the wound, and where these bands are found to terminate abruptly, or where in the tumour there are any hardness and irregularity, or pulpy matter, or substance which does not appear of the natural texture, the corresponding part of the Avound is to be examined, and the remaining disease extirpated. We must ever remember, that if tumours possessing malignity are only partially extirpated, they resent the injury offered to them, and resume a Avorse aspect than before. If Ave are to operate on a tumour Avhich has its seat in a gland, and if it be a mere ccirrhiu', there is a circumstance, Avhich if du- 238 OF TUMOURS. Iy attended to, will greatly facilitate its extirpation; Avhilst the body of the gland is hardening, the surrounding membrane is condensed. The pressure, and probably the slight inflam- mation, forms the cellular membrane into a distinct capsule. By bearing in mind that these hard scirrhous tumours are surrounded by a membrane, Ave are enabled to cut out a tu- mour from a seeming dangerous depth. I shall suppose that a patient comes to my reader with a hard tumour under the angle of the jaw, and which threat- ens to push toAvards the throat. The surgeon calculates the place of the arteries. He presses the root of the veins, and when they swell, hje sees Avhich are in his way. He then moves the tumour to ascertain Avhether its roots be deep, or if it has any firm adhesion; in doing this, he relaxes the muscles, and especially the platysma myoides. If the tumour has not encroached on the great vessels too much, if if has not adhered, and communicated its bad in- fluence to the surrounding parts, it may be extirpated. But my experience prompts me to say here, in the most confi- dent manner, that if the tumour be not sufficiently free in its attachments, but on the contrary, has pushed deep, and taken attachment to the jaw, or transverse processes of the cervical vertebra, no good will come of the operation. The patient after suffering considerable risl?, and being the sub- ject of a most painful operation, will have the mortification of finding the part grow hard soon after the cicatrization, and increase in its growth with a rapidity, Avhich the pro- gress of the tumour before the operation shall not have led him to expect. If it shall be determined to attempt the extirpation of an indurated and scirrhous gland, the surgeon has to provide himself with knives, and a strong hook, and a blunt hook for the assistant, with tenacula, and needles; but above all, Avith pieces of sponge having ligatures attached to them; and Avith adhesive straps, and a graduated compress and bandage. or TUMOURS,, 229 He begins his operation by cutting so that the fibres of the platysma myoides are cut across. To do this, it is not ne- cessary that he carries the incision across the neck, for in that case he Avould open veins needlessly; but I mean to Avarn the young surgeon against cutting betAvixt tAvo of the fasci- culi of the fibres of that muscle by Avhich he Avill find him- self restrained, in a most distressing manner, in the prosecu- tion of the dissection around the base of the tumour. The first incision being made through the skin, I have seen the operator begin his sweeping cuts round the tumour, forget- ful of the cutaneous muscle of the neck; and forgetful too of that essential circumstance, that the gland is noAv surround- ed with a proper capsule. If he begins to dissect round the gland before he has cut down to it, he will find himself in much confusion; and vessels bleeding in the progress of his operation which ought not to have been cut. He has therefore to lay back this cu- taneous muscle freely, and then he will find himself reAvard- ed for his decision by the gland starting more forAvard, and becoming, in fact, more superficial. But still he has not exposed the proper surface of the gland; if he cuts perpendicularly on the cellular coat which covers the tumour, he discovers that this cellular substance is a loose capsule, from which the gland can almost be turn- ed out Avith the point of the thumb! Avith the handle of the knife he separates the capsule from the glund :—he finds a part Avhere there is more resistance; a stronger union be- twixt the gland and capsule by a cellular cord; in this he Avill find the principal artery which supplies the tumour; and when he cuts this tag across, he must be prepared to take up the vessel Avith the tenaculum. In our dissections, every day we see, that the lymphatic glands have one principal ramification of a neighbouring arte- ry running into their substance. It is this same artery, Avhich by its activity enlarges the gland; and this artery, for the most part, is all a surgeon has to take up in the extirpation of the gland- 230 OF TUMOURS. If the operator is ignorant of this Avay of forcing the diseasw ed gland from its capsule, or has to operate upon a tumour which has no such capsule, his dissection is more tedious and difficult; and much more blood must be lost. If I am cer- tain that a gland has this capsule, I care not Iioav deep it may be seated ; I knoAv that I can extract it; but if it be of a different nature, and assimulated to the surrounding sub- stance, I am unwilling to attack it, because I have no guide to show me the extent of the disease; and because it hap- pens, that at every touch of the knife a vessel bleeds. If we have to extirpate a tumour of the nature of a bleed- ing fungus, like that described by Mr. Hey, or Mr. John Bell, we shall find no capsule formed by the condensed cel- lular substance. We must look well to the extent of the disease before Ave begin the operation; for it is not likely that we shall be able to mark the extent of the diseased sub- stance during the operation; we must here too be aware that the disease does sometimes extend further than the dis- eased appearance, and Ave must therefore cut freely away the surrounding parts if it be possible or safe. Where the smallest speck of tortuous vessels of the skin remains behind after the amputation of that tumour called aneurism by anastomosis, the tumour is quickly re-produced Avith an in- creased exuberance. If the tumour has been seated in the neighbourhood of a bone and has fixed upon it, though there be no appearance of disease in the bone apparent during the operation, yet from that source will the disease be re-produc- ed and propagated. I have so often seen bloody and painful operations per- formed on these tumours Avithout any good finally resulting from it, that I beg of my reader not to undertake the extir- pation of them unless he be resolved at all hazards to take all away that is tainted with the disease. In operating on these vascular tumours Ave must keep wide of their confines for another reason, to avoid blood, and the confusion resulting from it. If an adventurous young.sur- geon cuts into the body of a tumour of tortuous veins and OF TUMOURS. 231 arteries, he has vessels throAving out their blood over both his shoulders, and his attempts to tie these vessels are quite unavailing. But if he keeps Avide of the diseased mass he makes his dissection in the common cellular membrane, and perhaps only cuts across one artery Avhich throws out its blood with no uncommon velocity, although sufficient to sup- ply vessels with blood much more active than itself. I shall not stop to reason on this but state it as a fact worthy of the surgeon's attention. In operating on sacculated tumours, as we have understood that the sac is the source of the secreted contents, it is evi- dent that Ave must cut out the sac altogether, or Ave 6hall not eradicate the disease. If there be room enough, incysted tumours ought to be cut out entire. It may happen, how- ever, that they are situated in the orbit, and pressing on the eyeball, in which case after the integuments are dissected, as the knife cannot be pushed by the side of the tumour, let it be punctured, Avhich Avill give us room to proceed. The atheromatous tumours will sometimes burst of them- selves and discharge their contents, and heal. This circum- stance may tempt the surgeon, on some occasion, to puncture and press out the fluid from these tumours, and perhaps it may happen that after this only a fluid like the original mat- ter of the cyst be discharged from time to time; but the greater probabihty is that an irritable fungus rise6 from the opening. So we shall find that an imperfect operation on one of these wens, where a part of the cyst is left, is followed by inflammation, when if the disease had been extirpated the inflammation Avould have quickly subsided. These incysted tumours are cut off for the most part on ac- count of their size merely, but they do sometimes burst and push out a fungus, and become a source of irritation and erysipelatous inflammation; nay, tjie erysipelatous Mamma- tion from such a source has spread and sloughed, and the derangement of the constitution been such as to destroy the patient: on this account therefore are they to be extirpated.. I may here notice further that if we find that a fungus lu- 232 OF TUMOURS. mour has arisen from a Aven or incysted tumour, it is an encouragement to operate upon it. We hope that the deep- er part of the tumour is still separated from the surround- ing parts by the remaining cyst, and prevented from incor- porating Avith them*. An incysted tumour may be so situated that it cannot be, cut out, and yet something must be done to free the neigh- bouring parts from the pressure of it. I do not speak of the incysted tumours, the atheroma and steatoma, but of such sacs of fluid as wre may see about the tongue and throat, and which are imagined, but without any very direct proof, to be salivary tumours. These cysts ought to be freely opened. When punctured they inflame and thicken, and yeitf do not close altogether; even the seton does not obliterate their ca- vities, and Avhen they are inflamed and yet are not obliterat- ed, the sac thickens and becomes itself like a tumour. In my scheme of tumours I have mentioned under the head of incysted tumours, those containing blood. It is not always possible to distinguish these tumours of blood from such as have a proper secretion within the cyst, yet when they have no stool or firm sac, when by continued pressure we can empty them in a considerable degree, I am inclined to conclude that there is fluid blood contained in the tumour. * These tumours are soft, colourless, and as I have said com- pressible, and have no pulsation, and are very slow in their growth. These tumours soft, compressible, and without discoloura- tion, I have seen on the side of the neck. I have contemplat- ed the dismay of a surgeon on opening such a tumour with the lancet, when he found pure blood flowing from a tumour over the carotid artery! But there is nothing alarming in it: they can be compressed. The practice I would recommend in such a case, were it again to occur to me, is, after you have proved that you can command the blood from one puncture, to puncture and ex- * See Mr. Abernethy's Treatise. QF TUMOURS. 233 press the blood, and puncture it again and again in several places, then use compression. It may naturally be asked, why puncture to discharge the blood Avhen if can be pressed from the tumour Avithout this ? I propose puncturing not to discharge the blood, but to let it escape from the cells in which it is contained into the common cellular membrane, and to inflame the tumour, by Avhich alone Ave can expect the con- solidation of it, and the destruction of this cellular structure which receives and gives out the blood. I hope I need not again put my reader on his guard, to warn him against such interference as I here recommend in cases of such'vascular and bloody tumours as are described under the term aneurism by anastomosis, or tumours of blood av here there is pulsation or discoloured skin, or tortuous veins. On this last subject of tumours of the skin Avith discoloura- tion and tortuous veins, I have just to mention, that Avhen at any time they sheAV a disposition to greater activity, by a Avet bandage, by keeping a spongy cloth perpetually Avet over them, their tendency to increase may be checked. Of a tumour forming in a nerve. I have given a plate of a tumour in a nerve, which by the continued pain it gave wore out the patient's health and destroyed him at last. I knoAv not whether to consider this as a tumour of the nerve proper- ly, or only as a diseased groAvth in the interstice of the ner- vous filaments. However that may be, I consider it as very necessary to call my reader's attention to the symptoms of this disease, and further to intreat him to attend to the course and affections of the nerves someAvhat more than is usual, being convinced that by this he may be able to detect the nature or seat of disease when otherwise it will be impossible. It was but the other evening that a gentleman complained to me of a pain and numbness of the back of the thumb and fore- finger, this I found referable to a disease of the elboAV joint, and an affection of the muscular spinal nerve. I visited a woman with a disease of the womb, who complained of an un- usual pain and frequent spasms of the legs, I imagined that the disease had involved the sacro ischiatic nerve, and found VOL.

So Ave ascertain the seat of disease to be in the loies from the numbness of the thigh, and retraction of the testicle; and further from the knoAvledge of the peculiar nature of the pain from the injury of a nerve, I have been able to ascertain that a disease of the arm did not proceed from,the injury of the'nerve, when others thought it so evident that they sought to cut the nerve across. In wounds too Ave shall often be able to ascertain the precise track of the ball, and the very artery Avounded, by attending to the loss of sense of certain parts. lif a baltfhas made its (rack through the axilla I consult the sensation of tlie finger and arm, to tell me where it has passed ; and so indeed of the wounds of the pelvis, something definite may be learned * Avlien avc find that parts are rendered insensible Avhich are supplied by the anterior, middle, or great posterior nerve.

He suffered much from the bruise on the back of the thigh, but in a short time it got entirely t well. Some time after this, he began to be much troubled Avith a pain in his foot. This pain Avas in a part not likely to procure him much sympathy, and lie suffered much and ion^ Avithout attempting to procure assistance, or only such as the extremity of pain will put a man upon for the time. But the pain continued to increase from day to day, until it totally unfitted him for labour, exhausting and Avasting his OF TUMOURS. 2'3a> frame by continued Avatching. This pain Avas of a peculiar kind—it Avas confined to the bottom of the foot and Avas like an intense burning, while there Avas not the slightest disco- louration or SAvelling in the place. Often he Avould rise at night from his bed and stand on the cold stones, or plunge -* his foot into Avarm Avater or cold Avater, or into both alter- ^ nately. He noAv sought relief in a public hospital, and the attend ants there disconcerted Avith the strangeness of the symptom, which they did not comprehend, put him, as is usual on ♦ ? sucb^oxcasionf, on a course of mercury; but this trial of a . . medicine didj no good, and he went home.

'•■* if « , • ' K \^.V>; 1 am aware that some may conceive that this fchapter \ , . contains matter foreign to the nature of a system of surgery. I cannot agree Avith them: I Avrite for my pupils in the firsf " instance, and I know in Avhat they are most apt to err. Al-t * though I take all possible care in nay lectures to teach them a proper and manly Avay of studying\he arteries, yet I find them deficient in this branch of surgical anatomy, without *' Avhich their other joiowledge is useless. I think I was the first who taught my pupils the anatomy of the arteries in partial viewsrcut down upon them, and endeavoured to shew them in their natural confusion, and as they are seen in ope- ' ration, I have done this in the hope that my pupils might ' not be at a loss when they came to seek for bleeding arteries in the living body, as are those ivho have been taught the ana- tomy of the arteries on dried preparations, or at most shewn them on the -injected subject, after the dissection of the parts. When I say I Avas the first who taught the arteries thus, JL knoAv not that it is done even now by others; but I am cer- tain that the labours of men of the highest ability" must be less useful than those of the most ordinary capacity, if tlie former continue to teach on dry preparations, whilst the lat< ter take this method. Young men are too apt to fancy that when they have got a knowledge of the circle of operations, they are fitted for situations in the navy and army; but the first battle in Avhich they are engaged brings them to a mortifying conviction of their ignorance.

Class i. Arteries the wounds of which are necessarily fatal. The aorta, and pulmonic arteries—the arteria innominata— the cosliac—the superior and inferior mesenteric—the splenic —the emulgent—the common iliac, and the external and in- ternal iliac arteries, and the common carotids near the aorta. "Class ii. Arteries from which the bleeding is fatal if the vessel be not immediately stopped. The carotid artery—the femoral artery—the axillary bra- chial arteries—the profunda femoris and popliteal artery. * It is gratifying to find, however, that the college of surgeons are desirous of discountenancing this disgraceful method of teaching by question, so con- trary to the true spirit, and that when they discover the monotonous sound of this baby lesson, the candidate is brought to tlie full disclosure of his ig- norance, by some pertinent question, directly regarding the knowledge of the dead bodv. ». « 24Q ,. OF WOUNDED ARTERIESv > Class hi. Arteries, the bleeding from which is profuse and dangerous, and which require the ligature. These are the arteries of the leg—the ulnar and radial *, arteries—the gluteal and ischiatic arteries—the sub-scapularis —the thyroid and lingual arteries, and the branches of the profunda femoris. Class iv. Arteries which require careful compression, and if that be not possible the ligature—the internal pudic—the epigastric—the arteries in the sole of the foot and palm of the hand—the interosseous artery of the fore arm#;-the inter- ** costal arteries—the temporal and fascial artery, and occipital! arteries. Class v. This is a class of arteries that can be trouble- some only in cases of great weakness, or Avhen they are hi bones or fungous surfaces. , I. Ik there be bleeding from the hand or foot, and the sur- geon is called soon after the accident has happened, and be- fore any clumsy attempts have been made to stem the bleed- ing, he may put doAvn a piece of sponge into the wound, and then a graduated compress being applied, the vessel will be * effectually closed. But if the blood has been driven from » the mouth of the artery into the cellular membrane, and un- der the aponeurosis, the compress cannot be used Avith accu- racy and effect; neither can the tenaculum be used, because the mouth of the artery is hid; and the needle cannot be used, because the mouth of the bleeding artery is amongst nerves and tendons. So it happens that a wound of a trifling artery in the hand or foot requires the ligature of an artery of greater size in the Avrist or at the ancle. My reader now enquires Avhether all Avounds of the arte- ries of the foot and hand require a ligature ? Certainly not. I have seen the hand pierced and shattered in all directions by balls, and no ligature required. I have seen in the same OF AVOUNDED ARTERIES, 211 day three gun-shot wounds through, the palm of the hand, without haemorrhage; or more than Avas to be wished for. - In the use of a compress, this is not enough considered— that inflammation as well as pressure is required to the ob- literation of an artery. If there be a considerable thickness of cellular membrane, or a fascia, betwixt the lint or sponge * and the artery, the pressure may very likely fail, whereas if the compress had been put doAvn in contact Avith the artery it would surely have succeeded ; for then the pressure not on- ly keeps the sides of the vessel together, but the contact of the foreign body causes inflammation and adhesion. It will accordingly happen that the ulnar artery being wounded where it forms the arch in the palm of the hand, Ave shall in vain try to compress it; because the cellular mem- brane is charged with extravasated blood, and the artery has shrunk under the aponeurosis: the compress does not touch the artery and there is a great thickness of a substance like placenta over it. On another occasion finding an open wound, and the artery'displayed, and no such driving of the blood into the palm of the hand, and no such general swelling as in the last instance, the compress being put down into the wound and the hand bound over a ball of cotton or lint, the ha^ morrhage will be effectually suppressed. IL Ir is more difficult to say what size of an artery requires a ligature than may be at first imagined. It is very likely that while I am describing the manner of cutting down upon the arteries of the third class, the tibial or fibular, or ulnar arteries, a naval surgeon may say, « all this is superfluous, for I have stopt these arteries by compression." I have to shew that I know this, and yet that I deem it sometimes necessary to take up these A'essels with the needle. John Roe was shot in the arm and in the breast. He stood with the tackle in his hand ready to help in running out the gun, when a ehower of grape-shot shattered the men at the VOT.. IK H * m OF WOUNDED ARTERIES'. gun, killed two and wounded four. Roe felt his breath gone, and was sensible of a shot in his breast. The shot had pass- ed through his arm, breaking the ulna above the middle, and wounding the ulnar artery; it then passed obliquely over the scorbiculus cordis, very critically passing betAvixt the muscles and skin. Although there Avere circumstances in that Avound of the breast that might be interesting, yet it is to the Avound of the artery only that I have at present to call my reader's attention. The finger could be put into the Avound by which the ball entered, as well as that by which it passed out of the fore arm. These wounds were filled with lint, compresses laid on each, and a tight roller applied. There was at first no pain ; very little even Avhen the surgeon thrust his finger deep into the Avound ; but in half an hour the pa- tient felt the bandage tight, and became sensible of the cram- ming of the Avound and soreness. The shot holes Avere black at the second dressing; the dossils of lint were drawn out, but he had no recurrence of hasmorrhagy. It may be said that there was no absolute proof that the ulnar artery was wounded in this instance : in my opinion it was complete; but there can be no cavil about the folloAving fnstance. M'Kenzie was on the covering party, on the retreat from Villa Franca, and while reloading his piece he saAv a sharp-shooter of the enemy take his aim at him; the ball struck him in the fore arm; for the space of three miles of the retreat he bled freely from the Avound, but on finding the surgeon the arm Avas bound up and the bleeding Avas stopt and did not return. When I looked on this man's arm some days after, I was assured that the ulnar artery was in the di- rect course of the ball, and that it must have been cut through: the ulna was shattered, and many loose pieces lay in the bot- tom of the wound. I was confirmed in my supposition of the artery being divided, by the unusual irritation and pain in the Avound, which I attributed to the ulnar nerve being cut across, and now engaged in the fungous and ill-conditioned sore. The arm Avas amputated: the propriety of the opera- tion turning on other circumstances than what is to my pre- OF WOUNDED ARTERIES. 2U sent purpose. When I examined the part in dissection, 1 found the ulnar artery and nerve cut across, and on introduc- ing the probe into the artery, I found it stopt for tlie length of an kich and a half, in part owing to the contraction of the artery, but principally from the adhesion through coagulable lymph. I could give other cases of wounds which I have seen of the ulnar and radial arteries thus easily stopt by compression; but Avhat I have said is sufficiently conclusive on this point, viz. that Avhere these arteries are divided by gun-shot, com- pression is sufficient to stem the blood. I give here a sketch of a wound of the lingual artery, Avhich being of the scco»d order of arteries also, is I think conclusive on this head. The ball shattered the angle of the jaAV, passed obliquely through the tongue, and came out by the edge of the mastoid muscle of the other side. This wound bled for half an hour and then stopped. I judge that the lingual artery Avas wounded here, first from the course of the ball, as apparent to the eye; but also from this circumstance, to which I was care- ful to attend, viz. the insensibility of the left side of the tongue, which implied that the nerve was cut, 244 OT WOUNDED A&TERIEV'. III. The next inquiry which the intelligent young surgeon would naturally make, respects the necessity of tying arteries of the third class, when Avounded by a splinter or by a knife. The first question is not so easily answered as the second; let ns for example take the following case:-—In Lord Duncan's victory John Niel Avas stationed at a gun, Avhen a shot struck a bulk-head, and drove it in splinters, so as to throw doAvn and wound all the men at the gun; Niel was cut about the breast and throat with splinters, but not deeply. He went to the next gun and Avrought at it; Avhen as he carried a forty-tAvo pound shot betwixt his hands, a shot passed through the ship, and a very large splinter struck his arm and made him quit his hold. While he was looking at his arm two men were dashed against him, and all three tumbled down the hatchway. Niel was much sprained and bruised in the back by his fall*. When he could, he craAvled into the cock- pit, and found his arm bleeding very profusely. There Avert two wounds on the outside of the elboAV joint, through the belly of the supinator muscle. In one of them a large splin- ter Avas sticking, which Niel, while he Availed his turn to be dressed, endeavoured to pull away but could not. It was from this wound the bleeding proceeded : it was like a baH wound, and admitted the point of the finger, and Avas very deep. When the firing ceased the surgeon set this poor feK Ioav in a great chair, while he took his arm and tugged at the great splinter ineffectually. He therefore, at last, cut the wound open on one side, so as to free it, and it came out easily. If he had carried his knife into the other wound, which was close by it, he would have done good, for it afterwards ap- peared that there were many splinters in it, buried deep in * The reason I transcribe these circumstances is to bring xay reader ac- quainted with the very different kind of wounds aboard ship, from those to which the soldier is- exposed from grape and musket shot. The ease Walt communicated to me by my brother, OF WOUNDED ARTERIES. 24S the flesh, though not to be felt Avith the finger when it was pushed deep into the wound. Both wounds noAv bled pro- fusely ; the surgeon crammed them with flour, and laid a compress and a tight bandage over them. During two nights and two days the bleeding Avas so profuse as to indi- cate a wound of the ulnar artery; but partly because the bleeding was in some degree commanded by the compresses, and partly from want of assistance, the surgeon did riot undo the bandage. Niel was by this bleeding reduced very low. When the bandages were undone on the third day the bleeding had stopped. In this case we have a wound in the same arteries, but in circumstances materially different. The splinter of wood, although driven with the force of a bullet, yet wedged and cut its way no doubt; and while a ball, being round and obtuse, bruises as it passes, this splinter cut the artery. The bleeding was however stopped; but if the artery had been cut by a knife, it might have been more difficult: to shew which, I subjoin the following note of a case of wound of the radial artery, proving that a man may die from it :— IV. A gentleman was wounded in the fore arm by a pistol- shot The arm swelled prcdigfoudy; abscesses formed in the fore arm; and it was thought necessary to open them freely, and to rip up the fascia: in doing this, unfortunate- ly, the radial artery was touched. The bleeding was pro. fuse- and from the. weakness of the patient, critical: my reader may conceive from what has been described, that no- thing would be so eaiy as to compress this artery; but let him consider things as he will find them in practice, ihe man's arm is swoln to half the size of the body ; great ab- besses are in it; it is inflamed and so painful, that a heavy foot in the room, or the lifting of the thumb of the patient, gives excruciating pain. It is evident that the wound can- net be effectually stuffed and compressed Avhen m this state. 245 Ul AVOUNDED ARTERIEfc. I know not on Avhat grounds the surgeon determined in the preceding instance, but he took up the humeral artery, and not the radial artery. Still the bleeding continued. This put my notions of the effect of ligature into strange perplex- ity. Still the patient bled, and what could be further done ? —and in a short time he died. On dissection, I found the radial nerve with a firm ligature around it, but the humeral artery was not included. I never had seen the radial nerve mistaken for the humeral artery, but this was the third time I had found the radial nerve Avith a ligature around it. This is a pure case of a division of the radial artery, by the knife, proving fatal; and these cases leave no room for conjecture on the difference between gun-shot Avounds, those by splinters, and the clean cut of a knife. It is in this latter case especially that we have to cut dow n upon the artery and! take it up. V. I have stated that the branches of the profunda lemons require the ligature; but from the difficulty of the dissec- tion, the uncertainty in regard to the branch Avhich bleeds, and the precise place of it, Ave shall be long held in suspense, and perhaps obliged to trust to compression. In gun-shot wounds the case is still more perplexing. «F AVOUNDED ARTERIES. 247 In this slight sketch I have represented the place of the Wound of J. Chambers, of the rifle corps. He was wounded ih the retreat at Villa Franca; the ball entered under the edge of the sartorius muscle, passed obliquely through the flesh of the thigh, and round the bone, and lay under the skin near the trochanter major. The wound bled freely on his first receiving the shot. He was thrown on a mule, and for three leagues on the retreat he continued to bleed. The surgeon cut out the ball, and bound up the limb, and then the bleeding stopt; but it broke out again, and continued to bleed for ten days; and after this, when aboard the trans- port, there ay as great bleeding, so that they Avere obliged to apply the tourniquet, &c. The wound continued to bleed till within two days of his coming ashore. ' A Avound of the femoral artery would have prevented him from ever rising from where he fell. This has been a Avound of the branch of the profunda, which descends before the insertion of the long head of the triceps, and which is be- hind the great artery; yet although a branch, it is as large as the brachial artery, and its importance is shown by its continuing to bleed for thirteen days,—from its requiring the tourniquet eleven days after the Avound was received. This artery, however, was at last stopped by the compress and roller—but had it been cut with a knife the bleeding would most probably have been fatal, if the artery had been left unsecured. VI. It will not be denied, (though I know not where the inu portant fact will be found distinctly stated), that it is not the size of the artery which makes it to be dreaded, but its comparative size; and this not in comparison with the size and years of the patient only, but its principal importance hangs on the question whether—is it the main artery of a limb, or a branch ? From a branch of the profunda, equal to the brachial artery in size, tlie man is less likely to bleed to death, than if the wound is in the brachial artery. 248 OF TYING OF ARTERIES. VII. If a man is wounded in the main artery of the thigh, or arm, from the weapon entering in at the outside of the limb, it must be evident that the original wound cannot be enlarged to seek the artery, as has been proposed. To take the most favourable case for this proposal, I say, that if a man be wounded through the flesh of the triceps, and the sword pass into the humeral artery, we cannot dilate the wound to expose the puncture of the vessel. We must pass the gun-shot probe into the wound, and pass it forward un- til Ave can feel its point on the skin on the inside of the arm, and near the artery. Here Ave cut upon the artery, and make sure that this incision communicates with the original wound ; and if we do this, there can be no embarrassment from the artery continuing to bleed by the wound towards the outside, Avhile Ave are dissecting for the artery on the in- side of the arm. If in searching for the wound of an artery the blood does not flow, although you are sure that the side of vessels is wounded, compress the artery below the supposed place of the Avound, and the blood will start out. VHI. When we cut down upon the artery of a limb, and hav ing found it, are about to separate the vein and nerve from the artery, Ave must bend and relax the limb; by inattention to this rule I have seen the radial nerve tAvice included in the ligature put around the brachial artery. IX. It does not appear to me that surgeons have determined whether a single, or a double Jigature be required in case of a Avounded artery. I am sure that some nwv entertain these OF WOUNDED ARTERIES. 249 difficulties: viz. whether in certain cases a ligature being put around the artery above the wound, the patient is quite se- cure ? or if it be not necessary to tie the loAver part of the artery also ? On this subject I shall state Avhat appears to me to be the fact, and endeavour to draw the safe rule of practice. While these papers are before me my assistant is called to take up the radial artery, Avhere it has turned from the fore part of the Avrist. He finds a man with a deep Avound of a knife betwixt the fore-finger and thumb: the man has al- ready lost much blood; and introducing the probe it is found', that the point of the probe is at the head of the meta- carpal bone of the thumb. Tlie artery is taken up by the side of the extensor tendons of the thumb. The bleeding is stopped, yet in a short time the blood Aoavs again ; but the. wound being tied up, Avith a compress laid in the course of the wound, all is Avell. When a man is bleeding from the hand, or Avrist, or foot, tying the artery only diminishes the impulse of the blood, and does not entirely stop the Aoav of blood which comes round by the very free inosculations.— But the direct course of the blood being interrupted, our dressing is sufficient to stem the force of the hacmorrhagy by the anastomosing vessel; if the artery be not taken up, a sponge must be thrust deep into the Avound, and a tedious sore is the consequence ; but if the main supply be stopped, the lips of the wound can be brought together, and the com- press put over the integuments, (not into the flesh), and the wound healed by the first intention. If the surgeon be brought to a man who has received a wound in the inside of the arm, and he has reason to sup- pose, from the dashing of the blood, that the humeral artery is AArounded, ought he to be satisfied with pulling out some- thing from the bloody wound, and tying it ? nay, even sup- posing that he distinctly sees the extremity of the artery, and the blood floAving from it, is it sufficient to tie that mouth of the artery ? I believe, that Avith common care afterward, and due compression, the patient will not die of harmorrha- VOL.

These bandages not only prevent the early union of the cut, which is a minor consideration, but they do not allow the free circulation through the limb by the collateral arteries, noAv that the main trunk is cut and tied- When the main artery of a limb is tied we expect the free course of the blood by the anastomosing branches still to supply the lower part of the limb; and surely, Avhen we are so confident of this expectation, Ave cannot doubt the propriety of tying the arte- ry both above and below the wound, so that there may be no fear of hajmorrhagy from the returning blood, and no ne- cessity for a compress to be put into the Avound.

I take particular pleasure in producing the folloAving case, presented me by Mr. Torbit, of the Crescent, formerly a pupil of mine. A CASE OF DIFFUSED ANEURISM AVHICH HAPPENED AT THE SIEGE OF DANTZIC, MAY THE THIRD, 1807. A Polish pilot was offered a pecuniary reward, from the British Consul, to carry dispatches from General Kalkruth, commanding the garrison of Dantzic, to General Kaminski, commanding the allied Russio-Prussian army in the Fair Water. On his passase in an open boat down the Vistula, he Avas fired at by the French sentinels from both banks of the river, and received a Avound from a musket ball, Avhich entered the left arm from without, about two inches below the elboAv joint, the ball made its exit at the lower end of OF WOUNDED ARTERIES. 251 the ulna, carrying away both radial and ulnar arteries. A profuse haemorrhage followed, but he continued to exert his strength to get clear of the sentinels, until he fainted from the loss of blood; the boat Avas drifted d
