ABSTRACT
Acute shoulder pain is a common ED presentation with a wide range of pathologies that are often initially investigated with radiography. However, diagnosing rotator cuff injuries often requires further imaging for proper diagnosis and management. Bedside shoulder ultrasound is an application that allows for the evaluation of ligaments and tendons in addition to bony structures, all while utilizing direct patient feedback of focally tender areas, expediting diagnosis and therapeutic intervention. In this case series, we discuss our evaluation of patients with suspected rotator cuff pathology and the practice of using the stepwise shoulder ultrasound protocol. Four cases are presented that illustrate the use of shoulder ultrasound in diagnosing biceps tendon injury, supraspinatus tear, chronic supraspinatus tear with hemarthrosis, and subacromial-subdeltoid bursitis. This narrative highlights the valuable role of shoulder ultrasound for the expedited diagnosis and management of patients whose initial shoulder radiographs do not indicate any bony abnormalities.
