摘　　要：背景:股骨颈的前倾角是股骨内外髁后缘连线与股骨颈长轴所形成的夹角,涉及股骨两端的两个面,因此测量比较困难,方法很多,结果也有所不同。目的:通过对股骨解剖结构特殊性的仔细研究及对股骨颈前倾角定义的分析,探索一种CT测量股骨前倾角简便而又精确的方法。方法:选取行髋关节CT检查者80例,受测者双侧髋关节无器质性病变。在常规体位分别对同侧髋关节和膝关节进行扫描,然后计算出股骨颈前倾角,称为定义值;在中立体位对髋关节扫描,测量股骨颈前倾角称为实验值。结果与结论:股骨前倾角的定义值为(10.48±2.40)°,实验值为(10.29±2.10)°,两组间差异无显著性意义(P>0.05)。该实验值测量方法只需对髋关节扫描,可准确反映股骨颈前倾角,可为髋关节区病变的诊断和治疗提供确切的量化指标。BACKGROUND：Femoral neck anteversion is an angle between the posterior edge connection of the femoral condyle and the femur neck axis,involving the two ends of the femur.The measurement is more difficult,and many measurement methods lead to different results.OBJECTIVE：To provide the anteversion of the femoral neck criterion for imaging diagnosis of hip joint through CT measurement research.METHODS：Eighty adults who had performed CT scan were selected.The hip joints had no structural disease.In conventional position,the same side hip joint and knee joint were scanned and the anteversion of the femoral neck was calculated,called as definition value.In neutral position,the hip joint was scanned,and the anteversion of the femoral neck was measured,called as experiment value.RESULTS AND CONCLUSION：The mean and standard deviation of the definition value of anteversion of the femoral neck was （10.48±2.40）°.The mean and standard deviation of the experiment value of anteversion of the femoral neck was （10.29±2.10）°.There were no significant differences between definition value and experiment value （P0.05）.The method to measure experiment value was simple that was just to scan hip joint.Experiment value showed anteversion of the femoral neck exactly.It provided quantificat index for the diagnosis and treatment of hip disease.
