Conversion of a fused hip to total hip arthroplasty.

Background: Arthrodesis of the hip remains a viable treatment for severe unilateral arthritis after traumatic injury or infection in a young but otherwise healthy individual. The goal of the present study was to review the long-term clinical and radiographic results after conversion of a fused hip to a total hip arthroplasty and to identify the risk factors that would lead to a higher rate of failure.

Methods: We performed a retrospective review of the charts and radiographs of 187 patients (208 hips) who had conversion of a fused hip to a total hip arthroplasty.

Total hip arthroplasty in ankylosing spondylitis: an analysis of 181 hips.

The results of cemented total hip arthroplasty (THA) in patients with ankylosing spondylitis were studied to determine the utility of THA for these patients. A total of 103 patients with ankylosing spondylitis underwent 181 THAs; 72 patients (69.9%) had bilateral surgery.
