Cemented total hip arthroplasty with autogenous acetabular bone grafting for hips with developmental dysplasia in adults: the results at a minimum of ten years.

We carried out primary cemented total hip arthroplasty (THA) on 25 hips in 21 patients with developmental dysplasia of the hip, using autogenous acetabular bone grafts. The socket was placed at the level of the true acetabulum and bone from the femoral neck was used as graft. Five hips were excluded, leaving 20 which were followed up for a mean of 12.9 years (10 to 18). The mean modified Merle d'Aubigné and Postel functional scores were 5.6 for pain, 4.3 for mobility and 4.2 for range of movement. Radiological examination showed aseptic loosening in three sockets but not in the stems. The bone grafts had united and showed no evidence of late failure.
