Present methods of documenting internal rotation of the shoulder joint are based on the point reached over the back by the tip of the fully extended thumb. Disease or stiffness of the joints distal to the shoulder gives a false measure of internal rotation. Using the interepicondylar line of the humerus in the coronal plane as the neutral position, internal rotation can be documented accurately as the angle formed by this line with the coronal plane when the shoulder is rotated inwards.
目前记录肩关节内旋的方法是基于完全伸展的拇指尖在背部所达到的位置。肩关节远端关节的疾病或僵硬会给出错误的内旋测量值。以肱骨在冠状面的髁间线作为中立位置，当肩部向内旋转时，内旋可以准确记录为该线与冠状面形成的角度。
