Shoulder disorders are a very common problem. About 20% of the people experience shoulder problem at some stage in life. Shoulder pain is usually poorly localized, with the exception of pain that occurs in the acromioclavicular joint. Shoulder ultrasound is consistently used for assessing the rotator cuff. The ultrasound is as accurate as magnetic resonance imaging for the detection of rotator cuff tear. The USG scan can be used as a focused examination providing rapid, treatment, and real-time diagnosis in desired clinical situations. Ultrasound of the shoulder helps in diagnosing rotator cuff disorders, shoulder instability, and shoulder impingement. The examination requires appropriate patient positioning and attention to technique.
