[Superficial peroneal neurocutaneous vascular axial adipofascial-cutaneous flap pedicled with lateral supramalleolar perforator for coverage of donor site defects at foot dorsum].

Objective: To report the operative techniques and clinical results of modified superficial peroneal neurocutaneous propeller adipofascial-cutaneous flap for reconstruction of donor site defects at foot dorsum.

Methods: A propeller adipofascial flap with a skin pedicle (4-6 cm in width) based on the lateral superamalleolar perforating artery which vascularized the flap through the nutrient vessel chain of the superficial peroneal nerve was designed to repair defects after harvesting of foot pedicled dorsal flap. The defects at donor site of the leg was closed directly and split-thickness skin grafting was performed on the adipofascial surface of the flap primarily or secondarily.

Results: From May 2007 to Oct. 2011, 7 cases were treated. All flaps were transplanted successfully with satisfactory cosmetic and functional results. The flaps size ranged from 19 cm x 8 cm to 30 cm x 11 cm.

Conclusions: The flap has reliable blood supply with a relatively large vascularized area, long rotation are and minimum donor-site cosmetic morbidity. It' s a simple and safe procedure which is suitable for covering donor sites defects after harvesting foot pedicled dorsal flap.
