Digit replantation is when a doctor surgically reattaches a part of the body to restore function. Replantation works best when minimal damage has occurred, although most replantations are required because of trauma.
During surgery, a doctor will remove damaged tissue and reconnect bones with pins, screws or wires to hold the digit in place during the healing process and repair nerves, tendons and muscles. The reattached digit never regains 100 percent of its functionality, but the surgery is considered a success if the patient regains 60 to 80 percent of original use.
