Reason: rule out Right RTC tear or arthropathy History: pain and decreased ROM at right shoulder; heard popping sensation 6 mos ago when reaching out ROTATOR CUFF: The supraspinatus muscle and tendon appear intact. The infraspinatus muscle and tendon appear intact. The teres minor and subscapularis muscles and tendons appear intact.SUPRASPINATUS OUTLET: There is an os acromiale. The acromioclavicular joint is slightly widened with a small amount of fluid within the joint which may reflect prior surgery or trauma, but we see no edema within the distal clavicle or os currently. There is no frank fluid within the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is full-thickness loss of cartilage along the anterior superior glenoid as well as small osteophytes indicating osteoarthritis. There is also heterogeneity of the articular cartilage along the posteromedial aspect of the humeral head. There are small defects along the surface of the humeral head with underlying edema which may be degenerative in etiology. Fluid separates the anterior superior labrum from the underlying glenoid in the location of the aforementioned absent articular cartilage which may represent a tear or simply a prominent sublabral sulcus, exaggerated by the lack of articular cartilage.BICEPS TENDON: There is a lobulated collection of fluid within the bicipital groove surrounding the biceps tendon suggesting a tenosynovitis. The intra-articular portion of the tendon of the long head of the biceps appears normal.ADDITIONAL
1. Normal appearing rotator cuff.2. Os acromiale with slight widening of the acromioclavicular joint which may reflect old surgery or prior trauma.3. Osteoarthritis of the glenohumeral joint.4. Biceps tenosynovitis.
