背景：了解大转子、小转子和股骨头中心之间的关系有助于在髋关节置换术中获得满意的下肢长度，并且在无法参考手术髋对侧时可能更为重要。目的 测量股骨头中心、大转子、小转子的相对位置，并分析这些解剖标志之间的关系。方法：采用骨盆X线测量股骨头直径（D）、股骨头中心（C）至大转子的直线距离（G）、股骨头中心至小转子的直线距离（L）。分析数据的基本信息，计算G与D、L与D的比值，纳入性别、年龄因素后分析数据之间的函数关系，计算基础数据和比值数据的95%参考区间。结果：本研究共纳入97例患者194髋。直径D为5.08+/-0.43cm，距离G为4.68+/-0.45cm，距离L为4.28+/-0.49cm。 G/D比为0.92+/-0.07，95%参考范围为0.78-1.06。 L/D 比为 0.84 +/- 0.08，95% 参考范围为 0.68-1.00。将性别（g）纳入回归分析，得到回归方程G=1.890+0.536*D、L=1.129+0.620*D。年龄与距离G、L无关。结论：测量了G、D、L的基本数据，并分析了这些解剖标志之间的关系。
Background: Understanding the relationship between the greater trochanter, the lesser trochanter, and the femoral head center is helpful to achieve satisfactory lower limb length in hip arthroplasty, and it may be more important when the contralateral side of the surgical hip cannot be referenced. This work aims to measure the relative position of the femoral head center, the greater trochanter, and the lesser trochanter, and analyze the relationship between these anatomical landmarks.Methods: The femoral head diameter (D), the linear distance (G) from the femoral head center (C) to the greater trochanter, and the linear distance (L) from the femoral head center to the lesser trochanter were measured by pelvic X-ray. The basic information of the data was analyzed, the ratios of G to D and L to D were calculated, the functional relationship between the data was analyzed after the factors of gender and age were included, and the 95% reference intervals of the basic data and ratio data were calculated.Results: A total of 97 patients with 194 hips were enrolled in this study. The diameter D was 5.08 +/- 0.43 cm, the distance G was 4.68 +/- 0.45 cm, and the distance L was 4.28 +/- 0.49 cm. The G/D ratio was 0.92 +/- 0.07, and the 95% reference range was 0.78-1.06. The L/D ratio was 0.84 +/- 0.08, and the 95% reference range was 0.68-1.00. Gender (g) was included in the regression analysis, and the regression equations G=1.890+0.536*D and L=1.129+0.620*D were obtained. Age was not related to the distances G and L.Conclusions: The basic data of G, D, and L was measured, and the relationship between these anatomical landmarks was analyzed.
