基于股骨正位X片的人工髋关节术前优选系统的研究

Study of hip prosthesis preoperative super-selection system based on hip orthotopic radiograph

目的研究开发人工髋关节术前优选系统,为患者选择最优的人工髋关节。方法综合国内外人工髋关节选择的最新成果,对人工髋关节假体的形状尺寸特征进行了全面分析,结合股骨正位X片,制订了人工髋关节的选择原则,并进行几何和力学评价;使用MATLAB和VB混合编程开发人工髋关节术前优选系统。结果制订了优选准则与评价方法,开发人工髋关节术前优选系统。临床初步应用,已为患者成功进行了人工髋关节置换术。结论根据患者股骨正位X片及其股骨特征尺寸,该系统可以准确的为患者选择最优的假体。

Objective To research and develop the preoperative super-selection system for selecting proper prosthesis for patients. Methods This system integrates the latest achievements about hip prosthesis selection and analyse the characteristics of the hip prosthesis＇ figure and size based on hip orthotopic radiograph to set up the super-selection regulations. This Hip Prosthesis Preoperative Super-selection System developed with both MATLAB and VB could be also used to evaluate the select results from geometry and stress aspects. Results To develop the preoperative super- selection system, the guides and the methods for this super-selection were established and evaluated. Conclusion The super-selection system can make the proper choice of hip prosthesis for patients according to femur characters of patient＇s pelvis X-ray films.
