人工全髋关节置换术在强直性脊柱炎中的应用

The application of artificial total hip replacement in ankylosing spondylitis

目的探讨强直性脊柱炎全髋置换术的手术特点,评价其术后疗效。方法 14例强直性脊柱炎患者行人工全髋置换术,其中全髋单髋置换4例,全髋双髋置换10例。结果随访时间2～10年,平均5.25年。Harris评分由术前的平均26.33分(12～46分)提高到随访时的平均82.96分(74～96分),髋关节术前总活动度由术前的100.04°(0°～172°)改善为术后的185.38°(186°～247°)。14例术后均可生活自理。结论全髋置换术治疗强直性脊柱炎可获得满意疗效,选择合理的手术策略及合适的假体对手术效果尤为关键。

Objective To explore the surgery characteristics of total hip arthroplasty （THA） for patients with ankylosing spondylitis （AS）,and to evaluate the postoperative curative effect.Methods Forteen patients with AS were were given THA,in which 4 patients were given unilateral total hip arthroplasty,10 patients were given bilateral total hip arthroplasty.Results The follow-up time were 2 to 10 years with the mean of 5.25 years.Harris Scores increased to 82.96 scores （74-96 scores）from the mean of 26.33 scores before the surgery（12-46 scores）.Hip total mobility improved of 185.38 °（186°-247°） after the surgery from the mean of 100.04°（0°-172°） before the surgery.Forteen patients all could take care of themselves after operation.Conclusion Total hip replacement therapy of ankylosing spondylitis can be obtained satisfactory curative effect,chosing reasonable operation strategy and suitable prosthesis are keys to the operation effect.
