【摘要】 目的: 介绍经髋臼基底三联截骨术治疗青少年髋臼发育不良。方法: 2000年 3月~2004年 2月改进Tǒnnis术式, 设计经髋臼基底三联截骨治疗 22例患者。术前X线片显示:CE角为-25~15°, 平均 8. 4°; Sharp角为 45 ~70°, 平均 58. 6°: 臼头指数为 31% ~76%, 平均 61. 4%; ACP角为100~170°, 平均 139. 8°。CT片示: 髋臼前CE角大于正常, 髋臼前断面角和前倾角小于正常。CT三维重建示: 前、后外侧壁边缘角, 外侧髋臼倾斜角均大于正常, 水平面髋臼旋转角小于正常。结果: 16例 ( 16髋 ) 有 12 ~30个月(平均 20个月) 的随访结果。X线片示: CE角平均 32. 6°(15~52°), 比术前增大约 25°; Sharp角平均 41. 5°(38~46°), 减小约 18°; 臼头指数平均 81. 6% (69% ~89% ), 增大约 20%; ACP角平均 171. 1° ( 140 ~180°), 增大约31°。CT示: 髋臼前CE角和前倾角变小, 髋臼前断面变大。CT三维重建示: 髋臼前、后外侧壁边缘角变小, 外侧髋臼倾斜角变小, 水平面髋臼旋转角变大。结论: 经髋臼基底三联截骨术治疗青少年髋臼发育不良能够获得满意疗效。更多还原

【Abstract】 Objective:To introduce the periacetabular triple osteotomy for the treatment of adolescence acetabular dysplasia.Method:From March 2000 to February 2003,the authors had modified Tǒnnis triple pelvic osteotomy and designed periacetabular triple osteotomy creatively,22 patients with acetabular dysplasia were operated upon with the new therapy.Computed radiography preoperation showed:CE angle was -25～15° with an average of 8.4°;Sharp angle 45～70°,averaged 58.6°;AHI 31%～76%,averaged 61.4%;ACP angle 100～170°,averaged 139.8°.Shenton’s line broken.Computed tomography showed:ACEA justo major;AASA and AAVA justo minor.Three dimensional computed tomography showed:ALAL,PLAL and LAI justo major;TR justo minor.Result:Sixteen cases(16 hips)were followed up for 12～30 months,with an average of 20 months.Computed radiography showed:Average CE angle was 32.6°(15～52°),increased about 25°;average Sharp angle was 41.5°(38～46°),decreased about 18°;average AHI was 81.6%(69%～89%),increased about 20%;average ACP angle was 171.1°(140～180°),increased about 31%.Computed tomography showed:ACEA and AAVA decreased,AASA increased.Three dimensional computed tomography showed:ALAL,PLAL and LAI decreased,TR increased.Conclusion:The periacetabular triple osteotomy is a very safe and efficient procedure for the treatment of adolescence acetabular dysplasia.更多还原
