Crush, guillotine and avulsion mechanisms are three of the most common forms of traumatic amputation. Crush injuries are the most common and can result in significant tissue damage and injury. Because of the injury associated with crush mechanisms, amputations resulting from these forces are less likely to be successfully reattached. In contrast, guillotine injuries involve sharp edges, resulting in less tissue disruption. As a result, body parts that are amputated by guillotine forces are likely to have better reattachment and recovery outcomes.
