全髋关节置换术治疗髋关节发育不良并骨性关节炎

Total hip replacement in treatment of hip dysplasia and osteoarthritis

目的探讨全髋关节置换技术治疗髋关节发育不良并骨性关节炎的临床效果。方法对19例(22髋)髋关节发育不良并骨性关节炎患者进行全髋关节置换术。对手术时间、术中出血量、髋关节功能及畸形矫正情况进行分析。结果手术时间60～110(85.2±11.8)min,术中出血量300～1 200(650.3±157.7)ml。髋关节Harris评分由术前平均47.65±7.85分提高至86.54±6.30分。短缩肢体延长1.5～4.0 cm。19例均获随访,时间14～42个月,随访期内影像学显示假体位置正常;关节活动度满意。2例患者仍遗留轻度跛行。结论全髋关节置换技术治疗髋关节发育不良并骨性关节炎能显著改善髋关节功能,纠正髋关节畸形,近期疗效满意。

Objective To investigate clinical effect of total hip arthroplasty （THA） in treatment of hip dysplasia and osteoarthritis. Methods 19 patients （22 hips） with hip dysplasia and osteoarthritis were treated by THA, The oper- ation time, bleeding volume, the function of hip joint was analyzed and deformity correction. Results The operative time was 60 - 110 （ 85.2 ± 11.8 ） rain, the blood loss 300 - 1 200 （ 650. 3-± 157.7 ） ml, Harris hip score improved from preoperative average of 47.65 ± 7.85 points to 86. 54 ± 6.30 points. Shortening limbs were extended 1.5 - 4. 0 cm. 19 cases received follow-up 14 -42 months, Follow-up imaging showed position of the prosthesis was normal; Joint activity was satisfied. 2 patients were still left slightly limp. Conclusions THA for hip dysplasia and osteoar- thritis can significantly improve hip function, correct the deformity, and the shoit term effect is satisfactory.
