In the night, pains returned; agitation; some spasmodic motions; an anodyne draught administered in the morning. In the course of the day, these troublesome symptoms disappear; a slight swelling at the ancle. Third day, no pain; swelling gone; aliment increased. Sixth day, patient permitted to return to her usual regimen; extending rollers relaxed; lower one tightened: eleventh day, apparatus renewed; fragments in perfect contact: thirteenth day, limb moved incautiously; a slight shortening; apparatus reapplied; extending bandages drawn tight: sixteenth day, a disposition slightly bilious; evacuants administered with success: twenty-fourth day, a third application of the bandage: thirtieth day, progress in consolidation already very evident; the limb straight: fortieth day, extending rollers laid aside: fifty-second day, consolidation complete without the least deformity. 70. The muscular force, in children, being weak, and the weight of the body inconsiderable, have, in general, much less influence in producing a displacement in them than they do in adults. When, therefore, fractures occur in subjects under six or seven years old, the resistance, on the part of the apparatus, need not be so great. In general the lateral pressure which it makes, and the bearing of its different pieces against the limb, are sufficient to prevent the return of deformity, when this has been perfectly removed by reduction. 71. In such cases Desault covered the thigh with a circular bandage, made of a roller seven ells long, and three inches broad. Beginning with this below, near to the condyls, he carried it upwards, by oblique and reversed turns, to the pelvis, round which he threw a cast; then, giving the ball into the hand of an assistant, he applied four splints, one before, another behind, and one on each side: directing these to be held at their lower part near to the knee, he resumed the roller, and secured them firmly by a second series of circular and reversed turns, descending to the lower extremity of the thigh. The limb was then placed in a proper position, and, in general, of whatever kind the fracture was, whether oblique or transverse, this simple bandage, without the aid of permanent extension, was sufficient to retain it. 72. It would be difficult to determine the period necessary for the consolidation of fractures of the os femoris. Numerous circumstances concur to influence this work of nature, which is, in general, extended beyond the term of forty days, vulgarly assigned to it by the people at large. Besides, a stiffness of the limb, the inevitable effect of its long state of rest, still adds to the length of the patient’s confinement, by retarding the necessary motions, the return of which, as in other similar cases, can be accelerated only by exercise.
