背景:人工关节的脱位、松动、活动度未如理想等除与材料因素及术者技术相关外,还与假体大小型号等的选择有密切关系.目的:探讨人工髋关节置换术前模板测量软件的研发和初步临床应用的结果.方法:132例患者随机分为2组,分别使用课题组研发人工髋关节置换模板测量软件或传统方法对其髋关节置换过程中实际采用的假体型号行置换前预测,比较二者吻合率.结果与结论:通过人工髋关节置换模板测量软件选取的假体型号符合率为86.36%,而传统方法选取的假体型号得吻合率仅为71.97%,差异有显著性意义(χ2=13.794,P <0.001).软件置换前预测臼杯型号同置换中应用臼杯型号之间存在相关性(r=1.0000,P=0.015),软件置换前预测假体柄型号同置换中应用假体柄型号之间存在相关性(r=0.9999, P=0.029).说明数字化人工髋关节模板置换前测量软件研发成功,初步临床应用效果良好.

BACKGROUND: The dislocation, loosening, activity of artificial joint associated with the material factors and the surgeon technologies, but also closely related with the choice of prosthesis sizes. OBJECTIVE: To investigate the research of the software for measuring template before total hip replacement and its reliability in initial clinical application. METHODS: 132 patients were divided into two groups, the preoperative measurement of the prosthesis model that actual y used in the process of hip replacement was performed with the research and development total hip replacement template measurement software or traditional methods respectively, and final y compared the above results with the practical application at surgery. RESULTS AND CONCLUSION: The coincidence rate of prosthesis model measured by the software was 86.36%while coincidence rate of prosthesis model measured by traditional methods was 71.97%, the difference was statistical y significant (χ2=13.794, P < 0.001). There was significant correlation between software predicted preoperative acetabular prosthesis model and intraoperative acetabular prosthesis model (r=1.000 0, P=0.015), and software predicted preoperative femoral prosthesis model was significantly correlated with the intraoperative application of femoral prosthesis (r=0.999 9, P=0.029). The software for preoperative measuring is devised successful y, and the initial clinical application is wel .
