Abstract

After the success of total hip replacement arthroplasty by John Charnley in 1962, it was well known fact that total hip replacement arthroplasty can be applied to degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis, ankylosing spondylitis, even on the fused hip. However the old dislocated hip gives arise a few problem for its total hip replacement with the follwing causes:, 1. floor of the falad acetabulum is very thin and inadequate to receive a socket. 2. distorted anatomy of the acetabulum and proximal femur. 3. short and atrophic abductor mechanism. Total hip replacement arthroplasty could be successful for the old dislocated hip, if the adequate size of cup ard prosthesis are available and there is adequate length of the hip abductor. Preoperatively we can measure the size of the acetabulum and the distorted femur with roentgenogram. But it is not known how to measure or predict whether or not there is enough length of the abductor muscle mechanism preoperatively. Therefore the question arises how to measure or predict the length of the hip abductor in the old dislocated hip. Although this is a preliminary report, it is our feeling that the more the range of motion the hip has, the better the length of the hip abductor muscle. In our series acetabular socket can be positioned at the original site and the osteomized greater trochanter reduced to the femur easily in the cases more than 190 of total range of motion of the affected hips, The range of motion of the affected hip can be measured preoperatively.
