The anatomical examination of the distal end of the human humerus brings new perspectives. The lower extremity of the humerus is considered as a structure with two diverging columns that prolong the diaphysis and flank the trochlear mass articulate with the ulna. Two series of dry humeruses, one of 100, and the other 20 permitted a study with measurements of the posterior width of the columns, their antero-posterior dimensions, the angle that they form with the posterior longitudinal axis of the diaphysis. Dry bones, radiographs, and direct tracing were used. The second series of bones was used for cross-sections in several planes, and for perforations of the fossae. Lastly, graded cuts of frozen elbows were done. These methods showed the two columns to be completely different. The outer column is thick, quadrangular, bulky, convex at the back, wide, almost vertical; in front it bears the condyle, while a lateral facet appears on its distal part; this column is articulated with the radius and extends itself to the thumb column. The inner column is fusiform, narrow, oval on cross-sections; it is a column which supports the trochlea and the muscles, two roles played also by the outer column.
对人类肱骨远端的解剖学检查带来了新的视角。肱骨下端被视为一个具有两个分叉柱的结构,这两个柱延续骨干并在滑车块两侧与尺骨相关节。两组干燥的肱骨,一组100个,另一组20个,用于研究柱的后宽度、前后尺寸以及它们与骨干后纵轴形成的角度。使用了干燥骨骼、X光片和直接绘图。第二组骨骼用于多个平面的横截面以及窝的穿孔。最后,对冷冻肘部进行了分级切割。这些方法表明这两个柱完全不同。外侧柱厚、呈四边形、粗大、后部凸出、宽、几乎垂直;在前面它承载髁,而在其远端部分出现一个外侧小平面;该柱与桡骨相关节并延伸至拇指柱。内侧柱呈梭形、狭窄、横截面为椭圆形;它是一个支撑滑车和肌肉的柱,外侧柱也发挥这两个作用。
