Symptoms.—In posterior dislocations the leg is rotatedinward and fixed in more or less pronounced flexion andadduction. When the patient lies on his back, thisdeformity is readily recognized and is associated withshortening of the leg. It is greater in the iliac than inthe ischiatic form. The shortening is demonstrable byactual mensuration. The legs are brought into symmetricposition with respect to the pelvis, and the distances fromthe anterior superior spines to a point on the knee-joint—say, the lower edge of the patella or the median line of theknee—are measured. An easy method of estimating theshortening consists in flexing the two t
