title: Use of structural bone graft with cementless acetabular cups in total hip arthroplasty.
abstract: We retrospectively studied 15 primary and 13 revision total hip arthroplasties in which structural acetabular bone grafts were used in conjunction with cementless acetabular cups (for 11 type I segmental acetabular defects and 17 type III combined segmental/cavitary acetabular defects). Mean follow-up was 7.7 years in the primary and 6.8 years in the revision group. Radiographic analysis was performed to assess graft incorporation, component migration, bone-implant radiolucencies, and polyethylene wear. Two acetabular components (7.1%) were radiographically loose and demonstrated component migration. One of the two patients with these components also showed evidence of eccentric polyethylene wear. Three patients (10.7%) exhibited eccentric polyethylene wear. All grafts were well-incorporated radiographically without evidence of resorption. Modified Harris hip scores for all patients improved postoperatively.
