Reason: eval for rtc tear History: after lifting heavy object, pain to shoulder since Dec, 2015. 4/5 strength for abd and er. Several sequences are limited by patient motion artifact.ROTATOR CUFF: There is a full-thickness tear of the supraspinatus at its insertion involving the majority of the tendon, perhaps with a few intact anterior fibers. The tear extends posteriorly to involve the majority of the infraspinatus tendon, perhaps with a few intact posterior fibers. There is approximately 5 mm of retraction of the supraspinatus fibers and approximately 1 cm of retraction of the infraspinatus fibers. There is mild atrophy of the supraspinatus and infraspinatus muscles. There is increased signal intensity within the subscapularis tendon indicating moderate tendinosis and likely fraying of the undersurface fibers. There is mild atrophy of the subscapularis muscle. The teres minor muscle and tendon appear intact.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. There is a trace amount of fluid within the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Mild osteoarthritis affects the glenohumeral joint. There is minimal posterior translation of the humeral head relative to the center of the glenoid with what we suspect is a vacuum phenomenon within the anterior aspect of the joint. There is a small amount of fluid within the joint without evidence of a large effusion. Given the limitations of a non arthrogram study, the glenoid labrum appears normal for age.BICEPS TENDON: Given the limitations of a non arthrogram study, the tendon of the long head of the biceps appears normal for age.
Slightly limited study due to patient motion artifact showing near complete and slightly retracted tears of the supraspinatus and infraspinatus tendons, with other findings as described above.
