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.
在没有创伤性或先天性抓握功能缺失的情况下，将第二趾游离移植到手部是重建的可能性之一。接受移植趾的一个基本前提是通过血管蒂保证血液供应。第二趾的血液供应可以通过背侧或足底动脉，这是由于解剖变异所致。通过术前血管造影检查可以确定第二趾的动脉血液供应。在设计与手部受区血管的吻合时，必须考虑血管蒂的位置和长度。
