Lateral acetabular bone graft in total hip arthroplasty. A three- to eight-year follow-up study without internal fixation.

A series of 20 total hip arthroplasties were performed on 17 patients with significant acetabular deficiencies. Autogeneic femoral head bone grafting was performed without internal fixation. There was one failure caused by inadequate support of the graft, and this operation was revised. All grafts united within six months of surgery. Long-term follow-up evaluation revealed no evidence of progressive radiolucency or graft resorption.
