With a Report of the Microscopical Examination of~ a ISection of the Spinal Cord. By Henry Power, M.D., NEW YORK CITY ; PATHOLOGIST TO THE MOUNTAINSIDE HOSPITAL. H. P., aged twenty-four years ; single; teamster; born in New Jersey. Has a slight admixture of African blood, although he is very nearly white. Admitted to the Mountainside Hospital, January 12, 1893. Previous and family histories not of especial significance, except that the patient claimed to have come of healthy stock, and that he had never suffered from any serious illness in his life. He distinctly denied all venereal lesions. On admission the patient was quite helpless and was suffering acutely from an injury to the back, which he had sustained in the following manner: He was driving a team of horses attached to an excavating wagon, of which the driver's seat was very high. In attempting to drive into a barn he did not notice, until it was too late, that there was almost no space between the jamb of the door and the seat of the wagon. There was some ice upon the road and upon the approach to the barn- door, and the patient's horses were smooth-shod. As the latter ap- proached the door they began to slip, and naturally quickened their pace to get inside the barn. The patient tried to hold them back, and finding this impossible, he dropped his reins and tried to slide or roll off of his seat. In an instant he was caught between the door-jamb and the high back of the wagon-seat and pinned there until the team had pulled the wagon into the barn. He fainted away from pain and shock. After the door-jamb had been passed there was more room and the patient was pulled down from his exalted position and medical aid summoned. He thought that there was rather more than six inches of space between the door-jamb and the back of the wagon seat. When admitted to the hospital he was perfectly conscious, and, after morphine had been administered hypodermatically, passed a fairly com- fortable night. The next day he was not suffering any pain. His bladder was full of urine, of which he had passed none since his accident. He was completely paralyzed as to both sensation and motion in both 2 NEWTON, POWER*. FRACTURE OF A VERTEBRA. lower limbs. The line of anaesthesia in front was at Poupart's ligament, and behind at the upper extremities of the gluteal eminences-thus corresponding to the seventh zone of anaesthesia in Prof. Starr's tabula- tion (The Amer. Journ. of the Med. Sci., July, 1892). According to the Professor's observation this line of anaesthesia indicates a lesion of the cauda equina and filum terminale at the level of the second lumbar vertebra, and in my case the injury was afterward proved to be at this point. There was complete loss of the reflexes, both deep and superficial, below the seat of the injury. The patient could not feel the passage of the catheter, although he felt relieved after the water was drawn. The surface temperature was apparently somewhat raised over the lower limbs, but of this there was no certainty at the time, inasmuch as it took a day or two to procure a surface thermometer. The feet were also warm. But the ankle clonus could not be elicited. Although the rigidity of the joints of which Starr speaks (ibid.) was noticed, it was impossible by tickling or pricking of the soles of the feet to awaken any sensation or provoke any movement, reflex or otherwise. There was no priapism. No emesis. There was at this time no deformity nor bulging of the spinal column. No crepitus could be detected. None of the vertebral spines seemed to be missing or displaced. No bruises, lacerations, nor ecchymoses-in a word, no evidence of external violence was found on the man's body, although carefully looked for, and none subsequently appeared. It should be stated in passing, that the man was a short, stocky, heavily muscled person, and his spinal column was well walled in with firm muscular tissue. For the first three days after admission the temperature in the mouth was 101° F. ; pulse 80 to 86. Two drachms of compound licorice powder produced a copious stool, of which the patient was unaware. On the morning of the third day some bulging backward-of the spine was noted in the upper lumbar region. A plaster jacket was put on the patient, extending from the axillae to the hips. During its application he complained strenuously of pain, and twice nearly or quite fainted away, so that he had to be let down from the apparatus in which he was suspended and laid flat upon his back on the floor until he revived. The plaster jacket seemed to make him somewhat more comfortable and he could pull himself about in the bed by his arras. He complained more or less constantly of pain in the abdomen. Some suspicious-look- ing round, black spots appeared on his heels, and a number of small, oval, red ones. His urine was drawn three times daily with a soft catheter. For three days careful observations of the surface temperature were made with a Seguin's surface thermometer, about six minutes being consumed in an observation. They were as follows : Temperature on front of abdomen near umbilicus, 99°. Front of left thigh between hip and knee, 97° ; right, 94f°. Front of left arm between shoulder and elbow, 97° ; right, 98°. Front of left thigh between hip and knee, 99° ; right, 97°. Front of right thigh between hip and knee, 96 ; left, 98f °. Front of right arm between shoulder and elbow, 97f°; left, 95°. As these results seemed inconclusive the observations were discontinued. After a period of eight days without a movement from the bowels, the patient experienced great distress from tympanites of the abdomen, which became so excessive as to embarrass the respirations. Accordingly two drops of croton oil were given, and were followed in an hour and a half by an exceedingly copious action of indescribable fetor. This gave NEWTON, POWER: FRACTURE OF A VERTEBRA. 3 temporary relief, but was the beginning of fecal incontinence. About this time several small blebs were noted about the feet and ankles. On the 27th of January, after a consultation of the entire hospital staff, an operation was determined upon in the hope that something might be accomplished for the relief of this man's pitiable condition. The uncertainty and danger of the proposed operation had been ex- plained to the patient and his friends and their full consent to it obtained. It seemed better not to wait any longer, because the patient was daily losing ground, and we feared that he would not be in a condition for operation if a period of six weeks was allowed to elapse, as suggested by Dr. White and others, before undertaking an operation. Accordingly, I proceeded to operate with the assistance of my colleague, Dr. Love, and Drs. Ward, Whitehorne, and Francis, of the hospital staff. The plaster jacket was cut up the back and removed. There was a moderate posterior bulging of the upper lumbar vertebrae, and the most prominent of these seemed to be the second. We had agreed to do an Abbe's operation. A longitudinal incision, six inches long and one-half inch to the right of the vertebral spines, was made, beginning at the tenth dorsal vertebra and extending to the sacrum. The tissues were divided down to the laminae of the vertebrae. It was then observed that the second lumbar vertebra was displaced by having been rotated to the left, so that the hollow between the spinous and right transverse processes of this bone was nearly or quite in the median line of the back. The spinous processes of the remaining vertebrae were in their proper align- ment. A strong hook was employed, and several attempts were made to rotate this bone into its proper place, but without success, although an extraordinary amount of force was used. The arches of the first and second lumbar and the right transverse process of the latter were then cut away with a long pair of bone- forceps, exposing the medullary canal. The spinal dura mater had been torn by the original injury, so that only a small portion of the segments of the spinal cord that we had exposed was covered by its membranes. In fact, only a triangular-shaped piece of the dura mater, with its hypothenuse running from above downward and from right to left, was found. This covered probably a fifth of the two segments ; the remain- ing four-fifths of the dura mater we could not find. Of the cord itself a fusiform enlargement was observed, which probably increased the diameter of the cord by 50 per cent. This was purplish in color. No spiculm of bone and no blood-clots were observed in the medullary canal; nor so far as could be ascertained was there any pressure being exercised upon the substance of the cord. The patient now began to exhibit unmistakable signs of collapse. The operation had been long and bloody, and inasmuch as it seemed that little good and much harm might follow further manipulation, it was decided to close the wound and do nothing further. Considerable difficulty was experienced in stopping the hemorrhage, which was venous in character and welled up between the cut surfaces of bone. Affusions of hot water and pressure from sponges wrung out of boilkhg water finally stanched the flow of blood, and the wound was closed. A strip of iodoform gauze was used for a drain. The deep sutures were of catgut, specially prepared and kept in closed glass tubes. The muscular tissues wrere brought together With sutures of silkworm-gut. Every approved antiseptic precaution 4 NEWTON, POWER: FRACTURE OF A VERTEBRA. had been observed. Abbe's operation had, of course, proved impracti- cable owing to the displacement of the second lumbar vertebra. The patient was profoundly shocked by the operation. The next day his pulse was 132 and thready; temperature, 102° F.; and respiration, 28. In forty-eight hours the temperature fell to 97-1°, and then rose again to 102|°, at which point it remained until death. On January 31, 1893, five days after the operation, the patient had rallied somewhat and we felt some encouragement about his chances of recovery, albeit there had been no improvement whatever in the symptoms caused by the accident. On February 1st, however, his condition again became alarm- ing, and he died very quietly shortly after midnight, five and one-half days after the operation, and twenty-one and one-half days after the injury. An autopsy was forbidden. A hurried and surreptitious examination of the wound, however, revealed the following condition of things: There was no odor and almost no pus about the cut surfaces. A thin coating of lymph was noted over the exposed muscles, and indicated a healthy healing process. There was considerable laceration of the deeper layers of muscles from the original injury and from the use of the cutting forceps. The intervertebral substance between the first and second lumbar vertebrae was fractured nearly through. The body of the second lumbar was broken-the line of fracture beginning near the middle and running downward and forward to near the junction of the anterior and lower surfaces. A fracture of the intervertebral substance between the second and third lumbar, and of probably at least two of the articular processes of these vertebrte, must have existed, although from lack of time all the lesions could not be accurately made out. The swollen and discolored portion of the cord noted at the operation was removed and turned over to Dr. Henry Power, the pathologist of the Mountainside Hospital, for examination. His report is as follows: " The portion submitted for examination consisted of many of the roots forming the cauda equina, and also some more compact material among the fibres. The relations of the tissue to surrounding parts were in no way indicated. The tissue was hardened in bichromate solution of 2? per cent., and then in alcohol. Sections examined by Weigert stain and picro-acid fuchsin. The compact material above referred to was not part of the cord, as had been hoped, but consisted of blood-clot and some adhesions binding together the nerve roots. All the nerve fibres showed with the Weigert method the various stages of degenera- tion. No evidence, however, of the exact location of the injury causing the same was obtainable from the specimen." The explanation of the displacement and rotation to the left of the single vertebra (the second lumbar) seems to me to be that the patient was struck when leaning forward and to the right side, as he endeavored, when too late, to throw himself from his seat to the ground. (He would naturally sit on the right end of the wagon seat to drive, and would also naturally get on and off his wagon on the right side.) The habit of the colored race of ducking the head when danger threatens is well known; he therefore ducked his head and was struck by the door-jamb upon the right shoulder. His spine was already bent forward as much as possible as he was endeavoring to slide off of the seat and avoid the door-jamb at the same time. The blow broke his back at the point of NEWTON, POWER: FRACTURE OF A VERTEBRA. 5 the greatest curvature, the second lumbar, and also, since the legs were now held fast by having passed under the door-jamb, the same force displaced the entire spinal column above the fracture to the left. As, however, the wagon passed on, the man's body was drawn between the high back of the wagon-seat and the door-jamb, and since it could not pass with its transverse diameter perpendicular to the opposing surfaces, the body was forced on to the back, and the lateral dislocation was by t'his means reduced while the body was passing under the door-jamb. The second lumbar vertebra, however, was prevented from resuming its place with its fellows, because it was held fast by the high seat-back, a board about an inch wide. Thus the intervertebral substance between the second and third lumbar must have been fractured and the articular processes broken, if they had not been broken before. A lateral dis- placement with rotation would also account for the peculiar diagonal tear to the theca, and the partial reduction of the dislocation would account for the disappearance of the missing portion of the membrane, which was probably folded away against the side of the bony canal under the injured cord. Whether the above explanation be the true one or not, it is plausible. It is true that the best authorities seem united in the belief that a total abolition of the reflexes signifies a complete transverse destruc- tion of the cord, and also many of them hold that in cases exhibiting these symptoms an operation is contra-indicated. But considering the low seat of the lesion in my case, there is good authority for opera- ting, as, e. g., Prof. White, in the able summary of the " Surgery of the Spine," already referred to (Ther. Gazette, October, 1891), says (p. 680): "As to the region involved, both theoretical and statistical considerations show that the lower dorsal and lumbar vertebrae are those which can be operated on with the greatest hope of success." And again (p. 682) : " That it is unsafe to say in any given case that the cord is hopelessly damaged would seem to be fairly well established by the results of such cases as Horsley's, Macewen's, and Lowenstein's, so that operation should scarcely be refused on that score alone." And again (p. 683) he quotes Chipault as saying " Trephining is absolutely indicated . . . when there is compression of the filum terminale from any cause." And finally Dr. White lays down amongst the conclusions to his paper the following: "Resection of the posterior arches and laminae should be resorted to in all cases in which there is compression of the cauda equina from any cause." Having then so good authority for operative interference in this case, I cannot think that any injustice was done our patient by submitting him to an operation which, while it was by no means successful, has taught some valuable lessons, and at the worst only abridged by a comparatively short period a life already doomed, and thereby doubtless eliminated much suffering. 6 NEWTON, POWER: FRACTURE OF A VERTEBRA. The increasing number of reported operations undertaken for the relief of spinal injuries is, in my opinion (as Prof. White also holds), rather encouraging than otherwise to those surgeons who favor surgical interference in these cases; and who shall say that Sir Astley Cooper overstated the truth when he asserted that if one patient out of one hundred could be saved (by operation), it would be better than could be hoped for from Nature alone?
