    transverse plane as that occupied by the heads of the thigh bones when supporting this weight. The de¬ gree of extension of the pelvic and lumbar joints must therefore be considerable. This condition is less marked where the dislocation only exists uni¬ laterally , but is similar in its mechanics on the affected side. On exerting traction on the femur in a direction away from the joint, the capsule offered no resistance, but movement in this direction was opposed by all the muscles attached to the femur, by the fasciae and other soft parts. In order to remedy this very faulty mechanical condition it was clear that the best method would be to replace the head of the bone, or what repre¬ sented the upper articulating surface of the femur, in a cavity occupying the position of the normal acetabulum, or, in other words, in the transverse axis around which the normal pelvis rotates. Then by compensating for the shortening the pelvis could be rendered symmetrical. I would for one moment call your attention to the form of the upper end of the femur in this condition, since some writers seem to speak of it as if it were normal in form when they discuss the possibility of replacing it in an acetabulum which is presumably also of the natural shape when the subject has reached even adult age. This may possibly be true in certain cases, but it neither corresponds with my experience of the conditions found in the vast majority of patients operated on, nor with those which arguments by analogy afford. As far as I know, a growing bone remains normal only so long as it performs its normal functions. s
