An amputation injury is the removal of a body part, such as a limb or digit. It can refer to the cutting off of an arm, hand, finger, leg, foot or toe. Amputations can be traumatic or surgical. A traumatic amputation occurs when an extremity is removed during an accident, such as an arm getting cut off in a piece of machinery at work. A surgical amputation is when the removal of the limb is medically necessary to save the victim’s life or because the limb cannot be restored, such as removing an arm due to an untreatable infection or cancer.
