Sonographically detected subacromial/subdeltoid bursal effusion and biceps tendon sheath fluid: Reliable signs of rotator cuff tear?

Abstract

The sonographic detection of intraarticular fluid, SA/SD bursal fluid, or both has a low sensitivity and PPV in the diagnosis of rotator cuff tears. Isolated intra-articular and/or SA/SD bursal effusions are not reliable signs of rotator cuff tear.
