Abstract
Soft tissue defects around the ankle are common and must be covered with thin and pliable flaps. A regional flap, particularly from the dorsum of the foot was considered ideal. A neurocutaneous flap, based on the superficial peroneal nerve (SPN) and its branches was designed as a proximally based flap via cadaveric dissection. This study aimed to demonstrate the vascularity and characteristics of the superficial peroneal neurocutaneous (SPNC) flap. The SPNC flap was created in 11 lower limbs (seven cadavers) using a proximally based design. The skin flap was dissected at the dorsum of the foot, followed by injection of diluted methylene blue through the anterior tibial artery, to visualize the vascularity. The flap pedicle above the anterior ankle joint line was dissected along the SPN for anatomical study of perforating branches, paraneural vessels, and flap territory. The mean distances of the most proximal perforating branches were 1.51 ± 1.48 cm from the anterior ankle joint line, and 5.12 ± 1.78 cm from the lateral malleolus. The mean distances of the most distal perforating branches were 2.75 ± 1.54 cm from the anterior ankle joint line, and 5.90 ± 1.81 cm from the lateral malleolus. The mean number of perforating branches was 3.73 ± 1.49. The mean flap territories were 5.51 ± 0.59 cm in length, and 7.15 ± 0.64 cm in width. The SPNC flap is an alternative method for soft tissue reconstruction around the ankle with a proximally based flap design. The antegrade flow has been shown to offer effective vascularity in flaps prepared via cadaveric dissection.
