Traumatic hemipelvectomy (THP) is a catastrophic injury associated with high-energy trauma and high mortality. THP has been defined as a complete dislocation of the hemipelvis, often with disruption through the symphysis pubis and sacroiliac joint with concurrent traumatic rupture of the iliac vessels. Despite recent advances in prehospital resuscitative techniques, the true incidence of THP is difficult to ascertain because many patients die before hospital arrival. The leading causes of death associated with THP include blood loss, infection, and multiple system organ failure. Recognition and immediate intervention for these injuries is imperative for survival. The initial assessment includes a thorough physical examination assessing for signs of arterial damage and other associated injuries. Hemorrhage control and vigorous resuscitation should be prioritized to combat impending exsanguination. Emergent amputation has been found to be a lifesaving operation in these patients. The basis of this approach is rooted in achieving complete hemostasis while reducing complication rates. Understanding the nature of these massive pelvic injuries, the role of early amputation, and the importance of subspecialty communication can improve survivability and optimize patient outcomes.
