<unk>  is performed in response to traumatic amputation. Sharp, guillotine-type injuries with relatively uninjured surrounding tissue have the best post-replantation prognosis, with a success rate of 77%. Severe crush injuries, multi-level injuries, and avulsion injuries often mangle soft tissue to the point of precluding rejoining of essential blood vessels, making<unk>  impossible. In such cases, revision amputation of the stump may be necessary.
