摘　　要：目的通过尸体标本研究对经皮髋臼前柱拉力螺钉最有指导意义的导航参考图像。方法选取成年男性防腐尸体标本5具,将尸体标本仰卧于手术床上,连接、启动导航系统(型号medtronic),采集骨盆正位、入口位、闭孔斜位图像。在导航仪的帮助下逆行向髋臼前柱内拧入直径为6.5mm的空心螺钉,左、右两侧共10次。术后CT扫描髋臼,观察空心螺钉是否在髋臼前柱中。结果 CT扫描示10枚空心螺钉均在髋臼前柱内。结论骨盆正位、入口位、闭孔斜位的图像组合可以作为X线透视导航下经皮髋臼前柱拉力螺钉的参考图像。Objective To choose the reference image of percutaneous lag screw placement in the anterior column by studying cadaver specimens.Methods Cadaver specimens of 5 adult males were chosen.The specimens were lain on the operation table.The navigation system was connected and started,and the pelvis was examined by anterioposterior view and pelvis inlet view and obturator oblique view.The hollow screw under diameter of 6.5 mm was twisted retrogradely into the acetabular anterior column under guide of navigator.The left and the right acetabular anterior column of each specimen were all experimented.The acetabulum were scanned by CT and the location of screw was checked.Results All the screws were inserted into the acetabular anterior column.Conclusion The combination of X-ray views for anteroposterior position,inlet position and obturator oblique position can be taken as the reference image for percutaneous lag screw in acetabular anterior column.
