摘　　要：目的探讨3种不同方法测量的股骨前倾角值之间的相关性和差异。方法选取解放军总医院第四医学中心标本陈列室91例离体左侧股骨的CT数据,通过计算机软件生成三维表面模型,导入计算机辅助软件,分别模拟传统解剖学方法、基于CT的Reikerås法和基于CT的Murphy法对前倾角进行测量。观察指标:(1)分析3种测量方法测量结果的组间和组内一致性;(2)分析基于CT的Reikerås法、Murphy法的测量结果分别与模拟传统解剖学测量法之间的相关性和差异,以及基于CT的模拟Reikerås法、Murphy法的参考值。结果模拟传统解剖学方法测得股骨前倾角数值为14.8°±5.0°,基于CT的Reikerås法测量值为13.3°±7.2°,基于CT的Murphy法测量值为21.8°±7.3°。3种测量方法的测量结果组间和组内有良好的一致性(组内相关系数为0.960~0.987)。模拟传统解剖学测量方法的测量结果分别与基于CT的Reikerås法、Murphy法测量结果有较强的相关性(r=0.905、0.942,P值均<0.001),且测量值比较差异均有统计学意义(t=4.10、-21.52,P值均<0.001)。基于CT的Reikerås法、Murphy法测量股骨前倾角的参考值是13.7°~15.8°和20.3°~23.3°。结论基于CT的Reikerås法、Murphy法测量股骨前倾角均与模拟传统解剖学测量方法具有较强的相关性,但是不同方法得出的测量值存在差异,参考值也不同。Objective This study aims to evaluate the correlation and differences of three methods for measurement of femoral anteversion angles.Methods Ninety-one left femurs were selected for computed tomography(CT)data analysis,and 3D surface models were generated using computer software.The models were imported into computer-aided software to measure the femoral anteversion angles by using traditional anatomical methods,CT-based Reikerås method,and Murphy method.The following indicators were observed:(1)inter-and intra-observer consistency of the three measurement methods;(2)correlation and differences among CT-based Reikerås method,Murphy method,and the traditional anatomical measurement method as well as the reference values of CT-based Reikerås method and Murphy method.Results The femoral anteversion angle values were 14.8°±5.0°in the traditional anatomical method,13.3°±7.2°in the CT-based Reikerås method,and 21.8°±7.3°in the Murphy method were.Good inter-and intra-observer consistency was found among the three measurement methods(the interclass correlation coefficient ranged from 0.960 to 0.987).The measurement results obtained by the traditional anatomical method were strongly correlated with those obtained by the CT-based Reikerås method and the Murphy method(r=0.905,0.942;all P values<0.001),and the differences were statistically significant(t=4.10,−21.52;all P values<0.001).The reference values for measuring the femoral anteversion angle by using the Reikerås method and the Murphy method were 13.7°−15.8°and 20.3°−23.3°,respectively.Conclusion The CT-based Reikerås method and the Murphy method for measuring the femoral anteversion angle are strongly correlated with the traditional anatomical method,but their measurement and reference values differ.
