♤ A head transplant is a surgical operation involving the grafting of an organism's head onto the body of another. It should not be confused with another, hypothetical, surgical operation, the brain transplant. Head transplantation involves decapitating the patient. Although it has been successfully performed using dogs, monkeys and rats, no human is known to have undergone the procedure.
♤ This technique has been proposed as possibly useful for people who are already quadriplegics and who are also suffering from widespread organ failures which would otherwise require many different and difficult transplant surgeries. Quadriplegia may be an acceptable option for the terminally ill. There is no uniform consensus on the ethics of such a procedure.
