强直性脊柱炎非骨水泥型全髋关节置换27例

探讨强直性脊柱炎患者行人工非骨水泥型全髋关节置换的手术时机、手术方法及疗效分析。 方法：选择2000/2005湘雅医院收治强直性脊柱炎后髋关节强直患者27例33髋，均经Gibson入路行人工非骨水泥型全髋关节置换，全部采用Link公司Ribbed非骨水泥型人工全髋关节。比较髋关节置换前后Merle D’Aubigne评分及髋关节活动范围。 结果：27例33髋均获得随访，随访时间≥5个月，平均21个月。X射线平片示假体位置良好，无脱位，髋关节疼痛消失。各向运动良好。患者术后Merle D'Aubigne评分平均17.3分(16~18分)。 结论：对强直性脊柱炎进行人工非骨水泥型全髋关节置换可放宽手术年龄限制，根据患者的不同情况，在术中采取恰当的关节置换技术，均可恢复髋关节功能。

Cementless total hip arthroplasty for ankylosing spondylitis in 27 cases

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.
