BackgroundThe challenge of modern hand reconstruction goes beyond simple coverage. Thanks to the advances of microsurgery, there are ever-improving standards of functional and esthetic outcomes in hand reconstruction. The versatile donor site of the medial sural artery perforator flap can fulfill this purpose.MaterialsBetween June 2006 and October 2008, we used free medial sural artery perforator flaps for hand reconstruction in 14 cases. The sites of reconstruction included digits (n=7), dorsal hand (n=3), palmar hand (n=2), and wrist (n=2). Associated tendon and nerve defects were found in five patients. The plantaris tendon (n=4), split Achilles tendon (n=1), saphenous nerve (n=1), and sural nerve (n=1) were harvested for reconstructive purpose from the same donor site in this series.ResultsThe proximal perforator of the medial sural artery emerged 8 cm to 13 cm from the midpoint of the popliteal crease, correlating with the axis of the medial sural artery. Twelve flaps were raised with a single perforator. One flap failed because of perioperative vasospasm. The donor defect could be closed without skin grafts when the flap width was <6 cm.ConclusionThe free medial sural artery perforator flap transfer is appropriate for small- to medium-sized hand defect reconstruction. The donor site not only supplies a thin fasciocutaneous flap but also provides the option to harvest a segment of tendon or nerve graft through the same incision for composite tissue reconstruction in a single stage.Copyright © 2011 by Lippincott Williams & Wilkins
