Measurements of the maximum width and depth of the intertubercular sulcus (ITS), angles of the medial and lateral walls with the floor of the ITS, as well as the length of the humerus in 100 right and 100 left matched, unpaired dry humeri of 100 adults were statistically analyzed. Since 90-95% of the general population is right handed, on the basis of altered size of the dimensions of the right ITS relative to the left, it is proposed that greater width and smaller angles of the medial and lateral walls of the ITS of one side are indicative of handedness on that side. Handedness can further be deduced by the presence of a < 50 degrees angle of the medial wall and of a supratubercular ridge of Meyer on that side. The length of the humerus correlated with the width and depth of the ITS (P < 0.001). Regression equations of the length of the humerus on width, depth, as well as width and depth of the ITS have been derived.
对100名成年人的100对匹配的、不成对的干燥肱骨（100个右侧和100个左侧）的结节间沟（ITS）的最大宽度和深度、内侧壁和外侧壁与ITS底部的夹角以及肱骨长度进行了统计分析。由于90%至95%的普通人群是右利手，基于右侧ITS尺寸相对于左侧的改变，有人提出一侧ITS内侧壁和外侧壁更宽且夹角更小表明该侧为利手。通过该侧内侧壁角度<50度以及存在迈耶结节上嵴可进一步推断利手情况。肱骨长度与ITS的宽度和深度相关（P<0.001）。已得出肱骨长度关于ITS宽度、深度以及宽度和深度的回归方程。
