[The free groin flap utility. About 19 cases].

Introduction: The pedicled groin flap, well known for the hand resurfacing, has first been described by Mac Gregor in 1972. But the free groin flap is unpopular because of its short (5mm) and small artery (caliber 1,5 to 2mm) and a bulky aspect. The purpose of this study is to show its interest by weighing up the pros and cons of its advantages and of its disadvantages.
