[Description of a vascularized bone graft taken from the head of the 2nd metacarpal bone].

The authors describe a new vascularised bone graft from the distal part of the second metacarpal. They report an anatomic study on 20 cadavers which demonstrates the existence of two dorsal first web arteries (superficial and deep). The existence of free anastomosis between the two arteries is demonstrated. The vascularisation of the bone graft relies upon the deep first web artery which lies against the lateral aspect of the bone. The operative procedure is described and the authors stress the necessity to transfer the vascularized bone graft with a large soft tissue pedicle.
