Rotator cuff ultrasonography: diagnostic capabilities.

Dynamic shoulder ultrasonography is a noninvasive, accurate method used to assess the rotator cuff tendons. It can be incorporated into the in-office physical examination of patients at risk for rotator cuff problems. The low cost, convenience, and lack of risk make dynamic ultrasonography an excellent imaging tool for evaluating the biceps, subscapularis, infraspinatus, teres minor, and supraspinatus tendons. In-office ultrasound also provides an opportunity for patient education and explanation of management options.
