Impingement The exam is limited by motion artifact.ROTATOR CUFF: There is full-thickness tearing of the supraspinatus tendon with approximately 2 cm of retraction and what appears to be a small stump of tissue remaining on the greater tuberosity. There is also interstitial tearing within the retracted supraspinatus tendon more posteriorly. The aforementioned full-thickness tear extends posteriorly to involve the infraspinatus tendon anteriorly. There is additional interstitial tearing of the infraspinatus tendon along the myotendinous junction more proximally. There is mild to moderate fatty atrophy of the supraspinatus muscle with little if any atrophy of the infraspinatus muscle. The teres minor tendon and muscle are intact. There is full-thickness tearing of the subscapularis tendon superiorly with approximately 1 cm of retraction. There is delamination of the subscapularis which extends more proximally into the muscle although the muscle signal intensity is maintained.SUPRASPINATUS OUTLET: There is moderate osteoarthritis of the acromioclavicular joint. A small amount of fluid is noted in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is mild to moderate osteoarthritis of the glenohumeral joint with a slightly high riding humeral head. There is degenerative tearing of the labrum. There is a moderate joint effusion with scattered subcentimeter foci of low signal which may represent small loose bodies.BICEPS TENDON: There is increased signal and enlargement of the long head of the biceps within the rotator interval reflecting tendinosis. Irregularity of the margin of the biceps also suggests partial-thickness tearing. Fluid is present within the biceps tendon sheath reflecting extension from the glenohumeral joint.
1. Full-thickness rotator cuff tears and tendinosis further detailed above.2. Osteoarthritis of the acromioclavicular and glenohumeral joints.3. Tendinosis of the biceps tendon. Other findings are described above.
