Ultrasonography (US) is valued for its availability, tolerability, low cost, and utility in real-time dynamic evaluation.  Its use in diagnosing upper-extremity shoulder injury has expanded, but several features require definition before more widespread adoption can be realized.


 In particular, the evaluation of rotator cuff tears (RCTs) with US has been extensively studied, and authors generally agree that US is comparable with magnetic resonance imaging for the detection of full-thickness RCTs, whereas partial-thickness RCTs are more difficult to accurately identify with US.  Dynamic evaluation is particularly useful for pathologies such as subacromial impingement and glenohumeral instability.


 US has shown particular usefulness for the assessment of athletes, where there is additional motivation to delay more invasive techniques.  US has demonstrated promising results as a diagnostic modality for common shoulder injuries in athletes, and it is an important imaging tool that complements a thorough history and physical examination.
