44-year-old male with left shoulder acute injury with pain, limited flexion. Evaluate for left shoulder RC tear. ROTATOR CUFF: There is complete rupture of the subscapularis tendon with retraction of the proximal tendon fibers to the level of the glenoid. There is a tear of the anterior fibers of the supraspinatus tendon in the setting of mild tendinosis. The supraspinatus muscle appears normal. The infraspinatus and teres minor tendons and muscles appear normal.SUPRASPINATUS OUTLET: Note is made of an os acromiale, a normal variant, with associated edema.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is anatomic. There is a moderate to large joint effusion with debris indicating synovitis. There is degenerative tearing of the glenoid labrum. Mild osteoarthritis affects the glenohumeral joint. There are bone marrow changes likely due to anemia secondary to renal failure.BICEPS TENDON: The long head biceps tendon appears normal.ADDITIONAL
