Figure 3

MRI grade 3 (the arrow pointed in the figure): the attachment end of the greater tuberosity of the humerus in the supraspinatus tendon indicated emptiness and was filled with liquid signal shadow. It was found that the continuity of the tendon was interrupted and the broken ends were retracted. Effusion in the deltoid bursa below the acromion was found.
