中文摘要：

目的：通过计算机辅助对股骨头假体植柄通道的模拟研究，为人工全髋关节表面置换术股骨头假体植入方案提供更为科学的评估方法和预测手段。方法：选择无明显髋关节疾病的15具成人尸体标本，对整个骨盆进行连续CT扫描，将CT原始数据导入Mimics 10．1软件，重建出股骨近端三维模型。通过计算股骨头中心和股骨近端中心线，建立股骨颈轴线并确定股骨头假体最佳植柄通道，进行虚拟植入和三维可视化分析。结果：各维度观察股骨头假体植柄通道通过股骨头中心，位于股骨颈的中央。股骨头定位针模拟植入后假体柄干角与术前颈干角相比呈轻度外翻位，侧方偏移和水平偏移度较小，达到预期植柄方位的要求。结论：计算机辅助可以准确建立股骨头假体植柄通道并进行可视化分析，为个体化髋关节表面置换术提供了科学的评估方法和预测手段。

英文摘要：

Objective：To provide a scientific assessment and prediction method for femoral prosthesis implantation of total hip resurfaeing arthroplasty through computer - aided simulation research. Methods： Original data were obtained from non - obvious hip lesions specimen through spiral CT scan and then transferred into a computer workstation. After the 3D model of femur was reconstructed and calculated the center of femoral head and the centerline of femoral neck using Mimicsl0.01 software. We could find the axis of femoral neck, confirm the fem- oral prosthesis implantation channel and conduct implantation virtually, analyze based on 3 -dimensional visualiza- tion finally. Results： The femoral prosthesis implantation channel passed the center of femoral head and located in the middle of femoral neck. Short stem - shaft angle had a litter valgus compared with preoperative neck - shaft angle af- ter simulating implantation. The lateral and horizontal offset were small, So it met the requirement of expected loca- tion of implantation. Conclusions ：This accurate and effective method covers the shortage of conventional hip resurfa- cing arthroplasty and can provide a scientific assessment and prediction approach to individual preoperative plan of to- tal hip resurfacing arthroplasty.
