目的探讨人工全髋关节置换术治疗强直性脊柱炎的临床效果。方法选取2004年7月至2009年2月收治的行人工全髋关节置换术的强直性脊柱炎患者24例(33个髋关节),对其临床资料进行回顾性分析。结果本组术后平均随访24个月,患者Merle D’Aubigne评分:15～18分,平均17.2分;髋关节活动范围:屈伸平均50°～125°,外展内旋10°～50°,内外旋20°～45°。术后无切口及关节内感染,无脱位,髋关节疼痛消失。X线平片示假体位置良好,无松动,未出现异位骨化。术后髋关节活动度增加,屈曲挛缩畸形基本矫正(0°～5°)。结论人工全髋关节置换术可明显增加髋关节活动度,矫正髋关节畸形,改善髋关节功能,提高患者生活质量,是治疗强直性脊柱炎髋关节的有效方法。
Objective To investigate the clinical effect of total hip arthroplasty in treatment of ankylosing spondylitis. Methods Twenty-four patients (33 hips) with ankylosing spondylitis undergoing total hip arthroplasty from July 2004 to February 2009 were selected and their clinical data were retrospectively analyzed. Results The average follow-up time was 24 months in this group. The score of Merle D’Aubigne was 15-18, with an average of 17.2 points. The range of hip joint activity was 50 ° ~ 125 ° flexion and extension, 10 ° ~ 50 ° pronase rotation, Internal and external rotation 20 ° ~ 45 °. No incision and intra-articular infection, no dislocation, hip pain disappeared. X-ray showed a good prosthesis position, no loose, no heterotopic ossification. Postoperative hip mobility increased, flexion contracture deformity basically corrected (0 ° ~ 5 °). CONCLUSION: Total hip arthroplasty can significantly increase hip mobility, correct hip deformity, improve hip function and improve quality of life of patients. It is an effective method for treating hip joint of ankylosing spondylitis.
