Cementless total hip arthroplasty for ankylosing spondylitis in 27 cases / 中国组织工程研究

ABSTRACT

AIM: To explore operation opportunity and method and curative effect of cementless total hip arthroplasty (THA) surgery for treatment of ankylosing spondylitis. METHODS: Twenty-seven (33 hips) ankylosing spondylitis patients were selected from Xiangya Hospital between 2000 and 2005. All patients underwent THA with cementless prosthesis through Gibson approach. Ribbed cementless artificial total hip was provided by Link. Merle D'Aubigne score and range of motion joint before and after surgery were compared.RESULTS: Twenty-seven patients (33 hips) were all followed up for 21 months (at least 5 months). The X-ray showed that the prosthesis was in good position with no dislocation. The Merle D'Aubigne score was 17.3 in average (range 16 to 18) postoperatively. CONCLUSION: For ankylosing spondylitis patients, cementless THA has no rigorous limitation to surgery age. According to different patient conditions, THA correct technique could restore hip joint function.
