Pelvic ring disruptions in emergency radiology

Pelvic ring disruptions are a result of high-energy trauma and are a significant cause of morbidity and mortality in major trauma patients. The initial pelvic radiograph, in combination with computed tomographic imaging in selected patients, provides a quick and accurate method of diagnosing pelvic fractures. Pelvic fracture classification schemes have evolved over the past few decades, and include description of the mechanism of injury and assessment of pelvic stability. Understanding these classifications is important in developing an approach to interpretation of pelvic imaging and prediction of associated injuries. Armed with these tools, the emergency radiologist can detect pelvic fractures early and guide subsequent imaging and therapy
