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.
Patients with soft tissue defects of the distal third of the leg, ankle, heel, or foot requiring flap coverage.
Defect size greater than [Specify size, e.g., 5x5 cm] or involving exposed bone, tendon, or joint.
Palpable pulse in at least one of the major vessels Anterior Tibial Artery (ATA) or Posterior Tibial Artery (PTA)) at the ankle level.
Informed consent obtained from the patient or legal guardian
Patients with peripheral vascular disease (PVD) or diabetes mellitus (DM) or smokers
Comminuted fractures of the tibia & fibula
Patients requiring free flap coverage for massive defects or location beyond the RPAF's reach as the planter aspect of the foot
