Objective To evaluate the validity of the pelvic anterior plane ( PAP) as the reference plane for acetabular component implantation by analyzing the change of the pelvis inclination between the supine and standing positions. 目的分析卧位和站立位时骨盆倾斜度的变化情况,观察骨盆前平面作为髋臼假体植入的参照平面时的稳定性。
Conclusion Intraoperatively the pelvic anterior plane could be used as a valid reference plane for the implantation of the acetabular component. 结论骨盆前平面作为临床手术中髋臼假体植入的参照平面是稳定、可靠的。
