Some Recent Experiences in Clinical Surgery. (Illustrated by Notes of Cases, Pathological Specimens, and Patients ) BY DONALD MACLEAN, M. D. REPRINTED PROM THE Transactions of the Mich. State Medical Society FOR 1886. SOME RECENT EXPERIENCES IN CLINICAL SURGERY. (Illustrated by Notes of Cases, Pathological Specimens, and Patients.) DONALD MACLEAN, M. D. The first subject to which I desire to call the attention of the Association is the common one of diseased knee joints. Two cases have recently occurred in my public practice which have seemed worthy of presentation here, for the reason that they represent in a practical manner two important pathological conditions, demanding widely different methods of treatment, viz: in the one resection of the joint, in the other amputation of the thigh. A pathological specimen obtained from each one of these cases I have brought with me for inspection by those members of the Association who may feel an interest in the subject. Not only so, but one of the patients, viz., the one in which resection was performed, is present in the flesh for the purpose of giving ocular demonstration of the result of his treatment. Case 1. Charles M. , set. 19, Alpena, Mich., Englishman. History: about seven years ago, patient says that he had his left knee bruised between two logs. Notwithstanding the use of liniments, plasters, blisters, etc., the effects of this injury per sisted, and the joint grew steadily worse until August, 1884, when patient came to the University hospital at Ann Arbor, where Dr. Sullivan, in my absence, examined the knee and applied a plaster of Paris cast. From this the patient states that he experienced great relief. On October 10th following, patient returned to the hospital 2 EXPERIENCES IN CLINICAL SURGERY. and was examined by myself. The symptoms at that time pointed to chronic synovitis, and I advised continuance of the treatment by plaster cast, together with general tonics. He soon left the hospital feeling much relieved and in good spirits. On November 23,1885, patient once more entered the hospital. He then stated that all had gone well with his knee until March, 1885, when lie had the misfortune to give his knee a very severe wrench, in consequence of which he was confined to bed for two months. From that time until the date of his admission to the hospital the joint continued painful and swollen in spite of treatment, which consisted chiefly of extension by weight and pulley, with plaster casts. On admission at this time, November 23d, the general swell- ing of the joint; the thickened, gelatinous condition of the synovial membrane; the deep, gnawing pain, aggravated at night; the great tenderness on pressing the joint surfaces together, all testified unmistakably to general degeneration of all the joint structures, with ulceration of the articular cartilages. At the same time it seemed quite certain that the disease was confined to the immediate neighborhood of the articulation. In view of all the facts stated, I advised resection, and the patient gladly assenting, the operation was performed on January 14, 1886, in presence of the medical class. It was accomplished by making one long curved incision over the front of the joint, dividing the ligamentum patellae, but retaining it and the patella in the superior flap. The bones were not wired, but the flaps were drawn firmly together and supported by deep button sutures. The dressing consisted of antiseptic gauze and cotton wadding applied all over the surrounding parts, after they had been freely irrigated by a solution of mercuric bichloride, 1 to 2,000. Over these dressings a plaster of Paris cast, with a long posterior splint, was applied. January 18th. Dressings removed, when only about half a drachm of discharge could be detected. Irrigation, antiseptic dressings and a cast were applied. No rise of temperature BY OONALO MACLEAN. 3 occurred, and healing by first intention took place throughout nearly the whole extent of the wound. January 19th. A wrought iron splint, together with a plaster cast, was so applied as to admit of the thorough dressing of the wound, from which, however, there was not at any time much discharge. February 20th. Walked out with crutches. June 3d. Patient appeared before the class and walked from one end of the amphitheatre to the other without crutch or cane. His general health is completely restored, and here he is to speak for himself. (Patient looked healthy and walked freely without crutch or cane in presence of the Society. He still wore a light plaster cast as a precautionary measure.) The specimen obtained from this case was exhibited to the Society, and constituted a beautiful illustration of ulceration extending right through the cartilages of the joint and affecting the bones to a considerable depth. Elimination of the disease, consolidation of the bones, and consequent restoration of the limb to usefulness, will, in young adults, be more surely and quickly obtained in this form of disease by resection than by an}7 other mode of treatment; that is to say, after the usual con- servative procedures have been tried and have failed, as they will sometimes do. Case 2. The following case is interesting and instructive as showing a state of matters in which resection was contra-indicated and a more radical procedure called for. John R. , set. 37, Bennington, Mich. In January, 1875, patient’s left knee was injured by a block of wood falling on it, but from this complete recovery seemed to have been attained. Two years later patient says that he fell when running and severely wrenched the joint. A swelling in the popliteal space resulted from this injury, but has long since entirely disappeared. On admission the knee presented very little external signs of disease ; it was not swollen nor deformed. Nevertheless it was immovable and extremely painful, more especially at night—so 4 EXPERIENCES IN CLINICAL SURGERV. much so that sleep was greatly interfered with. Patient stated that last year he was under Dr. T. A. McGraw’s care, at St. Mary’s Hospital, Detroit, the treatment then consisting mainly of the application of the actual cautery and the use of plaster of Paris casts. After four months of this treatment he says that lie was not any better. It should be noted here that never during all the years dur- ing which his case had lasted had he been confined to bed, or the knee been subjected to continuous extension and counter extension. This was at once resorted to at the University hospital, but with no appreciable benefit beyond securing sleep. Amputation was advised as the only alternative, on the following grounds: First—The long standing and intractable character of the dis- ease testified clearly to the fact that the structural lesions were too deep seated and too extensive to admit of effectual relief, except by a radical operation. These lesions I conceived to be the following: (a) Ulceration of the articular cartilages and joint surfaces; (b) infiltration (fungous) more or less thorough of all the articular structures; (
