Case Report


Acute posterior shoulder dislocation is rare, and its early diagnosis remains a challenge to the emergency physician. This report describes two cases of acute posterior shoulder dislocation confirmed by bedside ultrasound scan performed by the emergency physician. Bedside ultrasound for diagnosis of posterior shoulder dislocation is accurate, noninvasive, repeatable, convenient, and without ionizing radiation. Dynamic ultrasound sign of posterior shoulder dislocation and using bedside ultrasound for verification of successful reduction of posterior shoulder dislocation are described.
