Management of Pelvic Ring Injuries in Unstable Patients.

High-energy pelvic ring injuries can represent life-threatening injuries in the polytraumatized patient, particularly when presenting with hemodynamic instability. These injuries mandate a systematic multidisciplinary approach to evaluation, and timely intervention to address hemorrhage while concomitantly addressing mechanical instability. These pelvic injuries are associated with potentially lethal hemorrhage originating from venous, arterial, and osseous sources. A thorough understanding of anatomy, radiographic findings, and initial physical examination can alert one to the presence of pelvic instability necessitating emergent treatment. The focus is on hemorrhage control, using techniques for skeletal stabilization, angiography, and open procedures to decrease mortality in this high-risk patient population.
