Extensor digitorum brevis rotational muscle flap for lower leg and ankle coverage.
BACKGROUND
Soft tissue reconstruction around the ankle has been a challenging problem. This article reports our experience using the extensor digitorum brevis muscle flap; some technical variations are discussed.


METHODS
The extensor digitorum brevis muscle flap is vascularized by the well-defined lateral tarsal artery, a branch of the dorsalis pedis artery originating at the level of the inferior extensor retinaculum. This flap was used for coverage of soft tissue defects in the lower leg and the ankle in 10 patients with various injuries.


RESULTS
All flaps survived completely. Complications included delayed healing of donor skin in two cases. Flap elevation was possible even in the traumatized donor foot.


CONCLUSIONS
The advantages of this flap include constant and reliable blood supply, easy and rapid flap dissection, adequate bulk, and one-stage procedure. However, disadvantages include the small size of the flap and the sacrifice of the dorsalis pedis artery.
