Extensor Digitorum Brevis Muscle Flap: Modified Approach Preserving Extensor Retinaculum

Abstract

Although numerous reconstructive options for covering defects over distal third of leg and dorsum of foot have been suggested, obtaining satisfactory cover remains difficult problem. Extensor digitorum brevis muscle flap as proximally or distally based island flap has been well described to be a promising alternative. Between 2004 and 2005, 10 defects over dorsum of foot and around malleoli were reconstructed with extensor digitorum brevis muscle flap. Six were proximally based and four were distally based flaps. Retrospectively, data were collected from these patients records like age, gender, type of injury, flap used, flap survival, complications, hospital stay, return to work. Mean follow-up period was 17.5 months (26-12 months). Of 10 flaps, one flap had failed (approximately 10%). Minor donor site problem presented in one case (10%). All patients returned to work after variable periods of rest (average 1(1/2) month). First web hypoesthesia was present only in two patients. This flap provides an excellent local option for small defects around ankle and over dorsum of foot. The advantages of this flap are its easy dissection, reliable blood supply. Disadvantages related to donor site can be minimized with careful technique.
