Celik A, Akoglu H, Omercikoglu S, et al. - In this study, the diagnostic accuracy of US compared with CT for the detection of rib fractures in patients who presented to the emergency department (ED) with blunt chest trauma (BCT). Researchers enrolled a convenience sample of adult patients who presented to the ED with thoracic pain after BCT in the last 24 h in this prospective, observational, diagnostic accuracy study. They compared the diagnostic utility of US conducted by an emergency physician with thorax CT. A total of 145 patients were included in the study. The results of this study demonstrated that a negative US of the site of the highest tenderness and neighboring ribs in a patient with BCT who presented to the ED with lateralizing pain decreases the possibility of a rib fracture significantly. Nevertheless, a positive US performs poorly to specify the exact location and number of the fractured ribs.
