The need for both pre-and post-reduction radiographs has recently been questioned when treating shoulder dislocation. Several case reports and case series have suggested that ultrasonography might be useful bedside diagnostic modality for evaluating shoulder dislocation. The purpose of this review was to evaluate studies that questioned necessity of radiographs for shoulder dislocation and also studies that evaluated bedside ultrasound as an alternative modality in shoulder dislocation. Ultrasonography can be used in patients with suspected shoulder dislocation. It cannot replace radiography because of possible associated fractures but it can be used before and after reduction to confirm successful relocation to reduce the risk of repeated sedation. It can also increase the certainty of physicians in cases that shoulder dislocation management needs to be performed without X-ray assessment.
