Dealing with post-traumatic arthrosis of the hip.

Abstract

The conversion of the arthritic post-traumatic hip may be more similar to revision surgery than routine primary hip replacement. Careful preoperative planning and templating is essential. Soft-tissue balance to produce stability is challenging, and patients may need bracing with a THR orthosis postoperatively to assure soft-tissue healing and stability. Acetabular bone stock may be significantly compromised, and the preoperative identification of bone stock deficiencies may not always be possible. The surgeon should be prepared with adequate allograft, acetabular reconstruction rings, and alternative procedures such as fusion or resection arthroplasty in these challenging cases.
