Eleven patients with ankylosing spondylitis underwent reconstructive hip surgery (21 hips). In 10 of these hips multiple surgical procedures had been performed. The final procedure included total hip arthroplasties (16 hips), femoral cup arthroplasties (four hips) and an Austin-Moore prosthetic replacement (one hip). A clinical and radiographic evaluation in the postoperative period revealed a high incidence of decreased joint motion and heterotopic ossification. Clinically moderate to severe restriction of motion was noted in 12 hips, and in six of these "reankylosis" was present. Radiographically moderate to severe new bone formation was seen in 11 hips, and in nine of these "reankylosis" was suggested. An association of excessive ossification and multiple surgical procedures was evident. It would appear that when the prime indication for hip surgery in patients with ankylosing spondylitis is restricted motion, the operation may not be beneficial.
