Preoperative imaging studies of patient (case 60) with extensive rotator cuff lesion (RC): a – anteroposterior radiograph shows the rise of the humeral head, b – resonance imaging (MRI) in the coronal T2 slice shows retraction of the supraspinatus tendon to the edge of the glenoid cavity (arrow) and the rise of the humeral head; c – axial T2 MRI, injury to the subscapularis tendon (arrow), d – sagittal T2 MRI, RC lesion including the supraspinatus and infra-spinal tendons (arrows), e – sagittal T1 MRI, fatty degeneration greater than 50% of the supraspinatus muscle (arrow).
