116. We discover, in general, that the cure is complete, from a disappearance of the signs of the fracture, more particularly from the motions of the great trochanter, in which circumduction[28] succeeds to rotation on its own axis, when the limb is made to move on itself, that is, to rotate outwards or inwards. The power of standing and walking is an infallible evidence of this reunion; nor are these exertions practicable, till the expiration of some time after it is completed; this circumstance is owing to a stiffness remaining in the parts around the joint, occasioned by long extension and a want of motion, and which exercise alone can effectually remove. (See what has been already said on this subject, in several parts of this work.) [28] A motion or sweep describing the arch of a circle. TRANS. 117. Numerous cases may be adduced in favour of the doctrine laid down in this memoir. But a sufficient number have been already published in the Journal of Surgery. I shall subjoin only two, drawn up by Manoury and Seveille. CASE VIII. Maria ***, aged forty, falling on the great trochanter, experienced a sudden pain, and heard a considerable report: she rose, however, and with difficulty made her way home. On the day following, a shortening of an inch was perceived in her thigh: the great trochanter was drawn backward and upward: walking was now impracticable, the foot remained turned inwards. Notwithstanding this latter circumstance, Desault, being called to the patient, declared that a fracture existed, which was evidenced in particular by a rotatory motion of the great trochanter on its own axis. The necessary apparatus being applied, was carefully examined every day by Manoury, to whom the patient was intrusted. No shortening of the limb occurred, nor did any unfavourable accident supervene, and, by the thirty-ninth day, the fracture was exactly and firmly united; on the forty-third, the splints were removed; and on the fiftieth, the patient could walk without assistance. CASE IX. John Rignal fractured the neck of the os femoris by falling, not as in the preceding case, on the great trochanter, but on the knee, which was bent at the time of the fall, while the shoulder of the same side supported a heavy load. He was brought to the Hotel-Dieu, where the same signs, as in the preceding case, (except that here the foot was turned inwards) furnishing ground for the same diagnosis, gave rise to the same treatment, which, in fifty days, was followed by a result equally favourable.
