Replantation refers to the surgical reattachment of a body part (such as a finger, hand, or toe) that has been completely cut from the body. The goal of replantation surgery is to reattach and restore function to as much of the injured part as possible.

Sometimes, replantation of a lost body part is not possible because the part is too damaged. If the lost part cannot be reattached, a patient may have to use a prosthesis, a device that substitutes for a missing part of the body. In some cases, a prosthesis may give a person without hands or arms the ability to function.
