Versatility of Intrinsic Muscle Flaps for the Diabetic Charcot Foot

For diabetic foot and ankle wounds, the abductor hallucis, flexor digitorum brevis (FDB), abductor digiti minimi, and the extensor digitorum brevis muscles have most commonly been reported.(1) These flaps allow for low donor site morbidity and decreased functional sacrifice when appropriately used. Intrinsic muscle flaps provide well-vascularized tissue with adequate composition capable of not only filling the defect but also having the ability to withstand high impact forces of ambulation. A case report is presented illustrating successful use of the FDB muscle flap for coverage of a plantar wound resulting from infection in a diabetic Charcot foot.
