ABSTRACT

Objective To review the characteristics and outcomes of primary total hip replacement(pTHR) in patients with ankylosing spondylitis(AS). Methods Eighteen patients (26 hips) with AS underwent pTHR from January 1991 to September 2003 were reviewed retrospectively. Sixteen patients (24 hips) were followed-up. The mean duration of follow-up was 85 months (ranging from 23 to 169 months). All patients were evaluated using Harris score standardization. Results There were 15 hips with hip ankylosis( 57.7%). The average time of the operation was 167.4 minutes (ranging from 90 to 350 minutes),the average volume of bleeding in the operation was 773.9 ml (ranging from 300 to 2000 ml),the postoperative average drainage was 488.6 ml(ranging from 50 to 1130 ml). The rate of excellent and good was 87.5 percent. Conclusion The pTHR is a very effective treatment for patients with AS. The perfect rehabilitation care is one of the main factors influencing the outcomes of pTHR for patients with AS.
