| 摘 要： | 髋关节置换手术中采用标准型假体时,术前只能大致选取假体,术中还要预备多个假体,往往手术时间增长。为了解决这一问题,本文提出一种利用计算机优选标准型髋关节假体的方法。从X线片中获取患者股骨解剖数据。利用这些解剖数据和股骨近端截面平均数据库三维重建患者股骨近端,重建出的股骨近端模型使优选标准假体成为可能。理论分析表明,该方法切实可行。

| Abstract: | In a hip replacement case when a standard hip stem is chosen,it is rough to select hip stems before operation,thus some stand-up standard hip stems should be prepared.The operation time is usually prolonged.In order to solve this problem,this paper presents a method to automatically select optimal standard hip stems by computers.Femoral anatomical data of a patient are acquired from X-ray films.Based on these anatomical data and a database of average cross-sections in proximal femurs,proximal femur of the patient can be reconstructed.This proximal femur model makes it possible to optimally select a standard hip stem.Theory analyses indicate that the method,presented in this paper,is practicable. |
