The head of the bone is so buried in the ischiatic notch, that it cannot be distinctly felt, except in thin per-sons, and then only by rolling the thigh-bone forwards as far as the comparatively fixed state of the limb will allow. The knee and foot are turned inwards, but less than in the dislocation upwards ; and the toe rests against the ball of the great toe of the other foot. When the patient is standing, the toe touches the ground, but the heel does not quite reach it. The knee is not so much advanced as in the dislocation upwards, but is. 60 DISLOCATION OF THE HIP JOINT, still brought a little more forwards than the other, and is slightly limb is so fixed that flexion and rotation are in a great degreeprevented.* Dissection.—There is a good specimen of this accident in thecollection at St. Thomass Hospital, which I met with accidentally, ina subject brought for dissection. The original acetabulum is entirelyfilled with a ligamentous substance, so that the head of the bone couldnot have been returned into it. The capsular ligament is torn fromits connection with the acetabulum, at its anterior and posteriorjunction, but not at its superior and inferior. The ligamentum teresis broken, and an inch of it still adheres to the head of the bone. Thehead of the femur rests behind the acetabulum on the pyriformismuscle, at the edge of the notch,above the sacro-sciatic muscle on which it rests isdiminished, but there has been noattempt made to for
