RESUMO
PURPOSE: To examine clinical outcomes of patients who have undergone arthroscopic treatment for hip pain in patients with ankylosing spondylitis. MATERIALS AND METHODS: Between April 2003 and May 2008, 9 early ankylosing spondylitis patients with hip pain who underwent hip arthroscopic treatment were analyzed retrospectively. Arthroscopic synovectomy was performed on all the patients and a spur resection was performed simultaneously on any patient showing osteophytes or spurs on their radiograph. The clinical results were assessed using the pain score and Harris hip score. RESULTS: All the patients showed normal to early arthritic changes except for 1 case in a hip simple radiograph and showed synovial hyperplasia in the arthroscopic findings. Seven patients showed specific spike-shaped spurs on the femoral head-neck junction. According to the pain score, the scores were 0.8 before surgery, 2.6 at 6 months postoperatively and 2.8 at the final follow-up. According to the Harris hip score, the scores were 47.4 before surgery, 87 at 6 months postoperatively and 91 at the final follow-up. CONCLUSION: Arthroscopic synovectomy and spur resection is a useful treatment for young adults with ankylosing spondylitis.
