Impaction bone grafting and a cemented cup after acetabular fracture.

Purpose: Patients suffering from post traumatic osteoarthritis of the acetabulum often require a total hip arthroplasty at a relatively young age. Long-term data outcome studies for this population are lacking. We report on the long-term outcome of 20 acetabular fractures in 20 patients treated with impaction bone grafting and a cemented cup after a mean follow-up of 18 years (range, 12-26 years).
