Traumatic hemipelvectomies are rare traumatic injuries with a forty percent mortality rate. It happens when half of the pelvis from the pubic symphysis to the sacroiliac joint is pulled away from the rest of the body in an open or closed injury. Because this is a situation that often results in death, it is important for the trauma team to do angiography to assess the circulation to the area, x-rays to determine the extent of the fracture and possibly a CT scan of the pelvis to determine what the injury looks like in three dimensions. Only aggressive surgical treatment can save the person’s life.
Because prehospital care has gotten so good, more and more people are arriving to the trauma centers alive rather than dead. This is a very unstable fracture with ligamentous injury and bony injury with external bleeding in some cases. The pelvic neurovascular bundle is usually destroyed, affecting sensation to the affected, partially-amputated leg.
