Abstract
Fifty eight total replacement operations were carried out on the hips with deficient acetabulum. The acetabulum was reconstructed by bone grafting. The active exercise was started one week after the operation and the partial weight bearing was allowed 3 to 4 weeks. Remodelling of the reconstructed acetabulum was completed in one and a half years after operation, and the stable fixation of the prosthetic socket was secured without one loosening in all cases.
