Computed tomography provides a non-invasive method for studying anatomy in live subjects. The abductor muscles of the hip were studied by using computed tomography to describe their position, size, and orientation. The outlines of the muscles were clearly identifiable; patterns that are associated with trauma, arthritis, and so on, differed from normal. The patterns in eighteen normal hips in twelve adults were mapped in detail. The cross-sectional areas of the abductor muscles were measured and vectors representing the total pull of the abductor muscle in the frontal and sagittal planes were constructed for each hip. The variations in individual and composite muscular anatomy were recorded. The inclination of the axis of the abductor muscle ranged from 17 to 26 degrees (standard deviation, 2.9 degrees) in the frontal plane and from -2 to 14 degrees (standard deviation, 4.2 degrees) in the sagittal plane.
计算机断层扫描为研究活体的解剖结构提供了一种非侵入性方法。通过计算机断层扫描对髋部外展肌进行研究，以描述其位置、大小和方向。肌肉轮廓清晰可辨；与创伤、关节炎等相关的模式与正常情况不同。详细绘制了12名成年人中18个正常髋关节的模式。测量了外展肌的横截面积，并为每个髋关节构建了代表外展肌在额面和矢状面总拉力的矢量。记录了个体和复合肌肉解剖结构的变化。外展肌轴线在额面的倾斜度范围为17至26度（标准差2.9度），在矢状面的倾斜度范围为-2至14度（标准差4.2度）。
