Total hip arthroplasty and acetabular bone grafting for unreduced fracture-dislocation of the hip.

Functional restoration after chronic persistent fracture-dislocation of the hip was achieved by total hip arthroplasty (THA) in two patients with history of severe multiple injuries. Acetabular deficiency was corrected by use of the femoral head as an autologous bone graft. A 24-year-old man and a 42-year-old woman were treated for persistent fracture-dislocation of the hip two years and one year, respectively, after the accidents. In both, total hip arthroplasty in combination with acetabular bone grafts, with the femoral head, produced satisfactory clinical results at follow-up periods of 59 and 55 months.
