Form and Function: Technique for Free Functional Gracilis Harvest With Greater Saphenous Vein for Large Skin Paddle.

Free functional gracilis transfer is a technique for restoration of upper extremity function following brachial plexus injury, as well as muscle loss from traumatic, oncologic, and congenital causes. However, when used for the latter applications, a functional muscle as well as large skin paddle can be required. Historically, skin paddle size was limited by venous outflow of the gracilis flap, using 1 or 2 venae comitantes, and large unreliable skin paddles resulting in partial necrosis. Therefore, to restore form and function, we herein present a technique of free functional gracilis muscle harvest with inclusion of adjacent greater saphenous vein for inclusion of a large skin paddle with 2 venous drainage systems.
