Reason: eval for superior labral tear History: L shoulder pain, positive O'Briens ROTATOR CUFF: There is a full-thickness tear of the rotator cuff at the junction of the supraspinatus and infraspinatus tendons approximately 1 cm proximal to the cuff insertion on the greater tuberosity. There is just under 1 cm of retraction of the undersurface fibers of the infraspinatus tendon. An undersurface component of the tear propagates into the posterior fibers of the supraspinatus tendon, and more posteriorly the tear also propagates distally through the infraspinatus tendon to its insertion on the greater tuberosity. There is a small cyst in the underlying humeral head. Overall, the tear is approximately 1.5 cm in AP dimension. There also appears to be insertional tearing of the fibers of the subscapularis tendon. We see no fatty atrophy of the subscapularis, supraspinatus or infraspinatus muscles. The teres minor tendon and muscle appear normal.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: Mild osteoarthritis affects the glenohumeral joint. There appears to be slight posterior/superior subluxation of the humeral head relative to the glenohumeral joint on the ABER view. Although we see no gadolinium entering the labrum, the superior labrum appears attenuated which may reflect chronic attritional tearing or debridement. The inferior labrum appears intact. BICEPS TENDON: The tendon of the long head of the biceps is identified within the bicipital groove but not within the rotator interval, which either reflects rupture or prior surgery.
1. Full-thickness rotator cuff tear as described above.2. Nonvisualization of the tendon of the long head of the biceps within the rotator interval may reflect prior rupture or tenotomy.3. Although we see no fluid-filled labral tear, the superior labrum appears attenuated which may reflect chronic attritional tearing or debridement.4. Mild osteoarthritis affects the glenohumeral and AC joints; other findings as above.
