71-year-old male presents with right shoulder pain, evaluate for rotator cuff tear. ROTATOR CUFF: There is a complete tear of the subscapularis tendon from its insertion on the lesser tuberosity. Portions of the tendon are retracted to the level of the glenoid. The subscapularis muscle appears normal. There is generalized thinning of the supraspinatus tendon likely reflecting chronic attritional tearing, but no full-thickness tear is identified. The anterior fibers of the infraspinatus tendon likewise appears thin, but without a full-thickness tear. The supraspinatus and infraspinatus muscles appear normal. The teres minor muscle and tendon are normal.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint. A small amount of fluid is noted within the subdeltoid bursa anteriorly.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is a glenohumeral joint effusion with fluid concentrated anteriorly. Intermediate signal intensity within the superior labrum may reflect degeneration. There is also enlargement of the anterior inferior labrum which may reflect degeneration or prior trauma.BICEPS TENDON: The tendon of the long head of the biceps appears intact, although edema anterior to the tendon at its transition from the rotator interval to the intertubercular groove may indicate injury to the pulley.
Complete tear of the subscapularis tendon and other findings as described above.
