It is possible to use the second toe instead of the thumb as an alternative to the hand-to-hand transplantation. In addition, in some patients, the thumb may be in place of the other four fingers as a fifth finger. In this case, it would be more appropriate to add an extra finger to the hand rather than to give proper function to the existing finger.
Although micro surgery is needed technically, it is a simpler and postoperative recovery process which is less risky compared to transferring from foot to hand.
