About this study

Official title: Resurfacing of Foot and Distal Leg Soft Tissue Defects Using Reversed Pedicled Peroneal Artery Flaps Augmented by Superficial Sural Artery: A Prospective Clinical Trial

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.

Read the detailed description

Soft tissue defects of the distal leg, ankle, and foot present a significant reconstructive challenge due to the limited availability of local soft tissue, the critical functional requirements of the area, and the high risk of complications such as osteomyelitis and unstable scarring. Traditional reconstructive options include local flaps, skin grafts, cross-leg flaps, and free tissue transfer. While free flaps offer robust coverage, they require specialized microvascular expertise, prolonged operative time, and are not suitable for all patients, particularly those with significant comorbidities or in resource-limited settings. The Reverse Peroneal Artery Flap (RPAF) is a distally-based fasciocutaneous or perforator-based flap supplied by the peroneal artery. Its survival relies on retrograde blood flow through anastomoses between the peroneal artery and the anterior and posterior tibial arteries around the ankle joint. Augmentation with the superficial sural artery has been proposed to further enhance flap perfusion and reliability. Pre-operative assessment includes clinical examination of the defect and peripheral pulses, Doppler ultrasonography to confirm patency of the anterior and posterior tibial arteries and to identify peroneal artery perforators, and plain X-rays to rule out osteomyelitis. CT angiography may be used in selected complex cases. The flap is designed along the axis of the peroneal artery perforators with the pivot point 5-7 cm above the tip of the lateral malleolus. The flap size is designed 1-2 cm larger than the defect. Elevation proceeds in a subfascial plane from proximal to distal, with ligation of the peroneal artery proximal to the most proximal perforator included. The flap is then rotated 180° to cover the defect. The donor site is closed primarily or with a split-thickness skin graft (STSG). Post-operative care includes limb elevation, close monitoring for venous congestion, and immobilization in a plaster of Paris splint for 3-4 weeks.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Reversed Pedicled Peroneal Artery FlapProcedure or surgery

    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.

Reversed Peroneal Artery Flap GroupExperimentalPatients with soft tissue defects of the distal leg, ankle, heel, or foot underwent reconstruction using a reversed pedicled peroneal artery fasciocutaneous flap augmented by the superficial sural artery. The flap was designed along the axis of peroneal artery perforators, elevated in a subfascial plane, and rotated 180° to cover the defect. The pivot point was placed 5-7 cm above the tip of the lateral malleolus. The donor site was closed primarily or with a split-thickness skin graft. Post-operative care included limb elevation and immobilization for 3-4 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants with Complete Flap Survival

    The number of participants whose reversed pedicled peroneal artery flap survives completely without total necrosis, requiring no further surgical coverage. Assessed via clinical examination of flap viability.

    Measured: 6 weeks post-operatively

Secondary outcomes (1)
  1. Number of Participants with Post-Operative Complications

    The number of participants who develop at least one of the following post-operative complications following flap surgery: venous congestion, partial or total flap necrosis, wound infection, or dehiscence. Assessed via clinical examination.

    Measured: 6 weeks post-operatively

Questions about this trial

What is this clinical trial studying?

A study testing Reversed Pedicled Peroneal Artery Flap in people with Soft Tissue Injuries and Leg Injuries, run by Assiut University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 5 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants with Complete Flap Survival (time frame: 6 weeks post-operatively). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Mar 2026.
