全髋关节置换术治疗27例髋关节发育不良合并骨性关节炎

目的探讨全髋关节置换术对髋关节发育不良合并骨性关节炎的临床疗效。方法对该院27例（33髋）髋关节发育不良合并骨性关节炎的患者施行全髋关节置换术,其中Crowe IV型患者9例（12髋）,CroweⅢ型患者12例（15髋）,CroweⅡ型患者6例（6髋）,对手术时间、髋关节功能、矫正恢复情况进行统计分析,所有患者随访3年。结果患者全部顺利完成手术,手术时间在65~120 min,术后双侧下肢长度差在0.5~3 cm,X片示人工髋臼均位于真髋关节窝内,假体无松动移位,末次回访髋关节Harris评分明显高于术前评分分别为术前评分（45.15±8.81）;36个月回访（87.88±6.33）],关节活动度均有不同程度改善,患者对治疗效果满意。结论全髋关节置换术是治疗髋关节发育不良合并骨性关节炎的有效方式,能够纠正关节畸形,改善关节功能,值得推广应用。

Total Hip Arthroplasty for 27 Cases with Hip Dysplasia and Osteoarthritis

Objective To explore the clinical effect of total hip arthroplasty on 27 cases with hip dysplasia and osteoarthritis.Methods 27 patients（33 hips） with hip dysplasia and osteoarthritis admitted in our hospital including 9 patients with Crowe type IV（12 hips）, 12 patients with Crowe type Ⅲ（15 hips）, 6 patients with Crowe typeⅡ（6 hips）, were given total hip arthroplasty. The surgery time, hip function and corrective recovery were counted and analyzed; all the patients were followed for 3 years. Results All the operations of the patients were conducted successfully. The operation time was 65 ~120min; the bilateral difference in leg length was 0.5~3cm after the operation; X-ray showed that artificial acetabulums were located in the true hip socket, no prosthesis loosening; the result of the last visit showed that Harris hip score was significantly higher than the preoperative score（preoperative score was 45.15 ± 8.81; the score at 36-month visit was 87.88 ± 6.33）; the range of motion was improved to some extent and the patients were satisfied with the treatment effect. Conclusion Total hip arthroplasty is an effective way for treating hip dysplasia complicated by osteoarthritis, which can correct the joint deformities, improve the joint function, and is worthy of popularization and application.
