Distally-based peroneus brevis muscle flap: A successful way of reconstructing lateral soft tissue defects of the ankle

Sixteen distally-based peroneus brevis muscle flaps were used to cover soft tissue defects in the lateral side of the ankle. The defect in 13 cases was on the lateral malleolus, in two on the lateral side of the calcaneus, and in one case in the Achilles tendon. The patients were all followed up until full recovery (mean 7.6 months, range 1.5–22 months). One flap failed to cover the defect and was replaced with a microvascular latissimus dorsi flap. In three cases minor revision and new skin grafting of the distal end of the flap was necessary. In 15 of the 16 patients the distally-based peroneus brevis muscle was successful in covering the lateral defect in the ankle. The technique of harvesting a flap is reliable, fast, and the overall success of the flap is good. The flap is particularly suitable for covering small or moderate sized defects on the lateral malleolus.
