The muscles of the thigh, by means of violent contraction, had drawn that portion of the os femoris attached to the external condyl upwards, and the superior fragment downwards. The sharp point of the latter had passed through the skin, and produced a wound of an inch and a half in extent, on the inside of the thigh, and a little above the condyl. The patient being undressed, was placed on a bed nearly horizontal, on which had been previously spread the necessary pieces of apparatus, disposed in proper order. Desault then examined the wound, extracted a splinter of the bone, covered the wound with lint, and then proceeded to the application of the apparatus which he usually employed in such cases (128). The extension was accompanied by no pain: on the other hand, it gave immediate relief: diluting drinks were prescribed. Next day, no pain; pulse a little raised; no dryness, nor any alteration of the skin; diet the same as on the preceding day; the apparatus wet with vegeto-mineral water. Fourth day, a new application of the apparatus, which had become relaxed; appearances of suppuration. From this time the dressing was renewed every other day, till the sixteenth, when the wound was cicatrized. After this the apparatus was not touched except when deranged; it was only wet from time to time with vegeto-mineral water, and great pains were taken to keep up the extension. The apparatus was not laid aside till the sixty-fourth day, although the callus appeared to have acquired a state of solidity somewhat sooner. The patient was soon in a situation to take exercise. The stiffness then disappeared rapidly, and, in about three weeks, he left the hospital, able to bend the leg to a right angle with the thigh, and under a full confidence that he would in a short time regain all the motions of the limb. § XXII. OF THE SUBSEQUENT TREATMENT. 131. As soon as the consolidation is complete, the motions of the limb must commence. These, at first gentle and confined, must be afterwards, increased in extent, and more frequently repeated, till, at length, the limb should be exercised every day for two or three hours without intermission. The position and direction of the leg ought to be constantly changed. One while, the thigh should be elevated by a bolster, so as to flex the leg; at another time, the bolster should be fixed under the leg to keep it extended. The rotula must be moved in every direction, and, as soon as the patient can leave his bed, he should take exercise himself. These precautions are more necessary here than in any other fracture, because a stiffness of the parts adjacent to the joint, is always the inevitable consequence of a long state of rest. Certainly writers would not have considered anchylosis as the most favourable termination of such fractures, had they been acquainted with the effect of exercise and rest in that now under consideration.
