Extensor digitorum brevis muscle flap using parallel incision

Abstract

A single incision is generally used to dissect the extensor digitorum brevis (EDB) muscle flap. However, in addition to exposure difficulties, this single incision may cause problems at donor sites, since both the dorsalis pedis vascular bundle and the sinus tarsi branch of the lateral tarsal artery require careful dissection. Thus, we modified the approach by using two parallel longitudinal incisions to expose the dorsalis pedis vascular bundle and the sinus tarsi branch of the lateral tarsal artery separately. Using this modified parallel-incision EDB muscle flap, we were able to reduce the operation times and donor site skin complications. © 2008 British Association of Plastic, Reconstructive and Aesthetic Surgeons.
