A roller and a kind of round splint applied to each side of the limb, forming the whole of the apparatus, and not being sufficient to retain the fragments, soon allowed them to overlap each other nearly two inches. The pains continue; a considerable swelling appears around the fracture; the patient is greatly agitated; he is brought to the Hotel-Dieu, where, from the deformity of the limb, Desault was satisfied, at first sight, of the existence of a fracture; on a more attentive examination, it was discovered to be complete and very oblique. The muscles being tense and in a state of violent contraction, drew the inferior fragments very forcibly upwards; these were finally, however, by means of well directed efforts, brought into perfect contact, with the superior fragments: the difficulty now lay in maintaining this contact. The age of the patient, his strength, and the almost convulsive state of the muscles, gave reason to apprehend that a displacement was about to occur. An attempt was made to prevent this in the following manner. The patient being laid on a bed properly prepared, 1st, The foot and the leg above the ancle, were covered by a bolster or compress, round which was passed a strong roller intended for the purpose of making extension. The ends of this roller, being left free, were carried, one on the outside, and the other on the inside of the limb. 2dly, Below the tubercle of the tibia was placed another bolster, surrounding the leg, and on this, was secured another roller for the purpose of counter-extension. The ends of this roller, after crossing under the knee, were left hanging loose one on each side of the limb. 3dly, The two rollers being thus arranged, while the assistants, still continued to make extension, the surgeon applied successively, and in the order already mentioned, the compresses, the bandage of strips, and the bolsters. 4thly, He then took two splints with notches in their lower ends, of the same breadth with the splints already described, but long enough to reach, each of them, from four inches above the knee to the distance of four inches beyond the sole of the foot. One of these was applied on the outside and the other on the inside of the leg. 5thly, The surgeon then taking hold of the two ends of the upper roller, drew them over the upper ends of the corresponding splints, while an assistant crossing the two ends of the lower roller under the sole of the foot, drew the external end over the lower extremity of the internal splint, and the internal end over the lower extremity of the external splint. Carrying them, then, up along each side, he brought them, at the middle of each splint, to meet the ends of the upper roller, to which they were firmly secured by knots, so as to make extension at the foot, and counter-extension at the knee. The two fragments, being drawn by this apparatus, the one down and the other up, could not again overlap.[36]
