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.
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.
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+0.536D and L =1.129+0.620D were obtained. Age was not related to the distances G and L.
The basic data of G, D, and L was measured, and the relationship between these anatomical landmarks was analyzed.
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实现满意的下肢长度，当无法参考手术侧的对侧时，这可能更为重要。本研究旨在测量股骨头中心、大转子和小转子的相对位置，并分析这些解剖学标志之间的关系。
通过骨盆 X 线测量股骨头直径（D）、股骨头中心（C）到大转子的直线距离（G）和股骨头中心到小转子的直线距离（L）。对数据的基本信息进行分析，计算 G/D 和 L/D 的比值，纳入性别和年龄因素后分析数据的函数关系，并计算基本数据和比值数据的 95%参考区间。
本研究共纳入 97 例 194 髋患者。D 直径为 5.08±0.43cm，G 距离为 4.68±0.45cm，L 距离为 4.28±0.49cm。G/D 比值为 0.92±0.07，95%参考范围为 0.78-1.06。L/D 比值为 0.84±0.08，95%参考范围为 0.68-1.00。回归分析中纳入了性别（g），得到 G=1.890+0.536D 和 L=1.129+0.620D 的回归方程。年龄与 G 和 L 距离无关。
测量了 G、D 和 L 的基本数据，并分析了这些解剖学标志之间的关系。
