OPERATIVE STRATEGY AND REHABILITATION IN THE MANAGEMENT OF PATIENT WITH ANKYLOSED HIP JOINTS CAUSED BY LATE ANKYLOSING SPONDYLITIS

Abstract

To investigate the effect of bilateral total hip replacement for patients with ankylosed hip joints caused by late ankylosing spondylitis (AS) and to discuss its related pre- and post-operation rehabilitation problems.

Data of 20 patients with ankylosed hip joints caused by late AS undergone total hip replacement (40 hips) were reviewed. Among the total 14 patients (28 hips) undergone bilateral total hip replacement, other 6 patients (12 hips) undergone twice operations. We used Harris score, assessment of the joint pain, range of motion to make sure the curative effect of the operative strategy.

The mean duration of follow-up was 3. 8 years, all hip joints function was improved, and the flexion deformity of the involved hips were disappeared. The range of hip flexion were 75°–105°(average 86. 2°), and the range of hip extension were 5°–15°(average 8. 7°), the average Harris score was from 32.8 pre-operation improved to 88.2 post-operation, the patients experienced no pain on their hips, the pain of the knee and the lower back complained before the treatment were obviously relieved.

Bilateral total hip replacement is an effective treatment for ankylosed hip joint caused by late ankylosing spondylitis, early rehabilitation intervention is useful for the functional recovery of the joints
