Distally Based Peroneus Brevis Muscle Flap for Reconstruction of Defects around the Ankle – A Retrospective Study
Background: Soft-tissue defects in the lower leg and ankle are a major problem for the reconstructive surgeon. Muscle flaps
bring in vascularity to the region of the defect and peroneus brevis muscle flap is a well-vascularized muscle that is used to
cover defects around the ankle as a distally based flap. Peroneus brevis is a muscle in the lateral compartment of the leg which
is muscular throughout its length and is expendable without any functional deficit.
Materials and Methods: This was a retrospective study of 10 cases of distally based pedicled peroneus brevis muscle flaps used
for coverage of defects of the lower leg and ankle between July 2018 and June 2021. There were nine males and one female
with an average defect size of 5 × 5 cm.
Results: The average flap length was 11 cm. The flap with split‑thickness skin graft was well settled in eight patients but two
patients had partial skin graft loss which settled by conservative management.
Conclusion: The flap is simple to harvest and safe for the reconstruction of small-to-moderate-sized skin defects of the distal
third of the tibia and all parts of the ankle as it has a reliable vascular supply. It provides a good cosmetic with a linear scar over
the lateral aspect of the leg.
