目的 :回顾 3 2例 ( 3 3髋 ) Staheli手术 ,观察其治疗儿童髋臼发育不良的疗效。方法 :采用 Mc Kay髋关节临床和 Willett X线片评定标准 ,对术后 3 2例 ( 3 3髋 )的疗效予以评价。结果 :平均随访时间 3 1( 3～ 70 )个月。临床优 3 1例 ,3 2髋 ;良 1例。X线片测量 :髋臼覆盖股骨头的百分比 ( % ) :正常组为 ( 85 .3 9± 7.0 5 ) % ,术前组为( 5 1.60± 10 .2 5 ) % ,术后组为 ( 10 9.5 6± 11.4 0 ) %。F值 =2 0 5 .4 4,P=0 .0 0 1。结论 :该术式操作相对简便 ,对股骨头的覆盖非常充分 ,是治疗儿童特别是青少年髋臼发育不良的理想术式之一。
Objective: To review 32 cases (3 3 hips) of Staheli surgery and observe its curative effect on acetabular dysplasia in children. Methods: The clinical efficacy of Mc Kay’s hip joint and Willett radiographs was evaluated in 32 patients (33 hips). Results: The mean follow-up time was 31 (3-70) months. Clinical excellence in 31 cases, 32 hips; good in 1 case. X-ray measurement: The percentage of acetabulum covering the femoral head (%) was (85.39 ± 7.05)% in the normal group and (5 1.60 ± 10.25)% in the preoperative group and 10 9.5 6 ± 11.4 0)%. F value = 2 0 5 .4 4, P = 0 .0 0 1. Conclusion: The procedure is relatively simple operation, the coverage of the femoral head is very full, is an ideal surgical treatment of children, especially young acetabulum dysplasia one of the ideal.
