The term amputation refers to the disconnection of all or part of a limb from the body. Specifically amputation it is defined as removal of the structure through a bone. This is in contrast to disarticulation, which is removal of the structure through a joint.
When due to trauma, traumatic amputation can be disastrous, severing vital structures. Whereas as surgical amputation is the controlled amputation that allows reconstruction of the stump (for function or prostheses use after). Amputations can also be congenital.
