Total hip arthroplasty for failed treatment of acetabular fractures: a 5-year follow-up study.

Total hip arthroplasty (THA) remains an available surgical option for failed treatment of acetabular fractures. We retrospectively analyzed 53 patients who underwent THA because of failed treatment of acetabular fractures. The mean duration of follow-up monitoring was 64 months (range, 32-123 months) in 49 patients. The average Harris hip score increased from 49.5 before surgery to 90.1 at the latest follow-up examination. Postoperative complications included 1 dislocation, 3 sciatic nerve injuries, and 3 class III instances of heterotopic ossification. There was only 1 revision due to aseptic loosening of the acetabular and femoral component. Despite the technically demanding nature of the procedure, the results of acetabular reconstruction are encouraging in these patients; complication rates are low, and patient satisfaction level is high.
