The shorteningis well shown by flexing the two thighs at aright angle with the pelvis. The top of the trochanter is, as shown bythe ilio-ischiatic line of Nelaton, not so much displaced upward as inthe iliac luxation. An everted dorsal luxation occurs, but it is anterior or inward dislocations usually arise from over-extensionof the hip with abduction and rotation outwards. They may, how-ever, occur during flexion. The suprapubic form has several variations in accordance with theexact spot at which the head rests upon the ramus of the pubes. Thesymptoms are flexion, abduction and eversion of the thigh, a prom-inence made by the femoral head on the top of the ramus of the pubes,pain and numbness from the anterior crural nerve being stretched overthe displaced bone, marked shortening of the limb, flattening of thegluteal region, the trochanter absent from its normal site but foundfurther toward the median line and near the acetabulum, the joint.

In the infrapubic, obturator or thyroid form there is slight flexionof the hip, abduction and eversion. These deviations are less markedthan the suprapubic in form. The leg has theappearance of being lengthened a little, the footis everted, the hip flattened in the region of thegreat trochanter, and the head palpable under theadductors or by the finger in the rectum. Theamount of motion, active or passive, is very slight,though it is said that the patient may be able towalk on the limb. Pain from pressure on theobturator nerve is to be expected. It is believedby some that the thyroid form is a common formand that it is sometimes converted into a posteriorby secondary i
