Pelvic injuries are serious, with mortality higher than 40% if the patient is in shock upon arrival at the hospital. These injuries are generally secondary to traffic accidents with violent kinetics, which explains the frequency of the associated extrapelvic lesions. With the vital prognosis at stake, management of these patients is a true challenge from both the radiographic and emergency care points of view. The objectives of this review are to present the epidemiological and physiological issues involved in pelvic injuries and the place of imaging today, necessarily integrated within a multidisciplinary team associating emergency physicians, surgeons, radiologists, and biologists.
