Traumatic amputation is the loss of a body part -- usually a finger, toe, arm, or leg-- that occurs as the result of an accident or trauma.

If an accident or trauma results in complete amputation (the body part is totally severed), the part sometimes can be reattached, especially when proper care is taken of the severed part and stump.

In a partial amputation, some soft-tissue connection remains. Depending on the severity of the injury, the partially severed extremity may or may not be able to be reattached.

There are various complications associated with amputation of a body part. The most important of these are bleeding, shock, and infection. (See wounds for more information.)

The long-term outcome for amputees has improved due to better understanding of the management of traumatic amputation, early emergency and critical care management, new surgical techniques, early rehabilitation, and new prosthetic designs. New limb replantation techniques have been moderately successful, but incomplete nerve regeneration remains a major limiting factor.

Often, the traumatic amputee will have a better outcome from having a well-fitting, functional prosthesis than a nonfunctional replanted limb.

Traumatic amputations usually result directly from factory, farm, or power tool accidents or from motor vehicle accidents. Natural disasters, war, and terrorist attacks can also cause traumatic amputations.

• A body part that has been completely or partially cut off
• Bleeding (may be minimal or severe, depending on the location and nature of the injury)
• Pain (the degree of pain is not always related to the severity of the injury or the amount of bleeding)
• Crushed body tissue (badly mangled, but still partially attached by muscle, bone, tendon or skin)
