改良Colonna手术后髋臼发育的远期变化

The Long-term Outcome of Acetabulum Development Following Improved Colonna Operation

目的观察改良Colonna手术后髋臼发育的远期变化。方法对比120例术后5年以上的双髋X光片和随机选择的与随访时年龄相近的120例正常的双髋正位X光片,仔细测量髋臼指数、CE角、臼头指数和髋臼深度,对单侧者还进行双侧对比测量。结果改良Colonna手术组髋臼的各项指标与正常组对比,差异无显著意义。球窝形髋臼占72.67%,无骨盆变形,无髋臼囊变。结论改良Colonna手术不会影响髋臼的生长发育,促进髋臼发育的关键是股骨头的同心圆复位及股骨头的形态。

Objective To observe change of the long-term development of acetabulum following improved colonna＇s procedure. Methods Acetabular index,CE angle,acetabuar head index and acetabular depth were carefully measured on roentgenograms of 120 developmental dysplasia of the hip cases over 5 years post-operation and 120 normal children whose age were similar to sick children as control group during following-up. Results There was no statistical significance of the above indexes between the children with improved colonna＇s procedure and those of normal control ones.The spherical socket acetabulum accounted for 72.67%.There were no pelvis deformation and cystoid variation in acetabula. Conclusion Modified improved colonna＇s procedure is no affect on acetabular growth.The key factors promoting acetabular development are concentric reduction of femoral head and capital head shaoe.
