Summary

Wounds involving the skin and soft tissue of the lower leg, ankle, heel, and foot can be difficult to treat because there is very little skin and tissue available in that area to cover the wound. When the wound is large or involves exposed bone or tendon, a flap, which is a piece of skin and tissue moved from a nearby area, is needed to close it.

This study evaluates a surgical technique called the Reversed Peroneal Artery Flap (RPAF). In this procedure, a flap of skin and tissue from the outer side of the lower leg is lifted and rotated to cover the wound. The blood supply to the flap comes from the peroneal artery, which runs along the fibula bone, and is augmented by the superficial sural artery to improve flap survival. The study will include 30 adult patients who have soft tissue defects of the distal leg, ankle, heel, or foot. All patients will undergo the RPAF procedure at Assiut University Hospitals, Egypt. The main goal is to measure how well the flap survives after surgery. Secondary goals include assessing complications, functional recovery, and the condition of the donor site.

PROCEDURE

Reversed Pedicled Peroneal Artery Flap

A distally-based fasciocutaneous flap supplied by the peroneal artery, augmented by the superficial sural artery, used for reconstruction of soft tissue defects of the distal leg, ankle, heel, and foot. The flap is designed along the peroneal artery perforators, elevated in a subfascial plane, and rotated 180° around a pivot point 5-7 cm above the lateral malleolus. Flap survival relies on retrograde blood flow through anastomoses between the peroneal artery and the anterior and posterior tibial arteries. The donor site is closed primarily or with a split-thickness skin graft (STSG). Post-operative care includes limb elevation and immobilization in a plaster of Paris splint for 3-4 weeks.
