[Anatomical variations in blood vessels and their effect on the technic in toe transfer].

In the absence of grasp, either traumatic or congenital, free transfer of the second toe to the hand is one of the reconstructive possibilities. An essential prerequisite for the acceptance of the transferred toe is a guaranteed blood supply through the vascular pedicle. The blood supply of the second toe can be either by dorsal or plantar arteries, a fact which is due to anatomic variations. Through preoperative angiographic examination the arterial blood supply of the second toe can be defined. The location and length of the vascular pedicle have to be considered in the design of the anastomosis with the recipient vessels of the hand.
