The aim of this study is to reveal the relationship of the shoulder joint components from humeral elevation using X-ray. We selected 39 people without current shoulder symptoms or history of previous injuries of the shoulders. The X-rays were taken both arm at side and the maximum elevated position of the shoulder joint. As the result of this study, humerus was abducted 167.78 degrees. Clavicle was shifted 16.85 degrees. Sternum was shifted 8.1mm inferiorly. CL angle was 123.72 degrees. Scapular upward rotation was 51.89. The relation of each component has a significant correlation between ABD and scapular upward rotation, scapular upward rotation and clavicle, sternum and clavicle, CL angle and clavicle, and to take part also by ABD in the CL angle and the GH angle. During elevation of the arm, the scapular upward rotation and the range of GH joint took great part adding the small part of momentum of the clavicle. It was possible to guess at the motor function of the component during shoulder elevation with 2 pictures, and it's use as some help in functional diagnosis was suggested.
