We retrospectively reviewed 54 patients (92 hips) who underwent cementless total hip arthroplasty for bony ankylosis in ankylosing spondylitis between September 1988 and 2002. The mean age of the patients was 25.5 years. The mean duration of follow-up was 8.5 years. The average preoperative Harris Hip Score of 49.5 improved to 82.6 postoperatively. Postoperatively, 10 hips had mild to moderate pain. Anterior dislocation occurred in 4 (4.3%) hips, and sciatic nerve palsy in 1 (1.1%) hip. Heterotopic ossification was seen in 12 patients; reankylosis rate was 0%. Thirteen (14%) arthroplasties were revised because of aseptic loosening. Kaplan-Meier survivorship analysis with revision as end point revealed 98.8% survival at 5 years and 85.8% survival at 8.5 years follow-up.
我们回顾性分析了1988年9月至2002年间因强直性脊柱炎骨融合接受非骨水泥型全髋关节置换术的54例患者（92髋）。患者的平均年龄为25.5岁。平均随访时间为8.5年。术前Harris髋关节评分平均为49.5分，术后提高到82.6分。术后，10髋有轻至中度疼痛。4髋（4.3%）发生前脱位，1髋（1.1%）出现坐骨神经麻痹。12例患者出现异位骨化；再融合率为0%。13例（14%）关节置换因无菌性松动而翻修。以翻修为终点的Kaplan-Meier生存分析显示，5年生存率为98.8%，8.5年随访生存率为85.8%。
