[Distal extensor digitorum brevis muscle flap. Report of 2 cases].

The authors describe an original technical modification of the extensor digitorum brevis muscle flap. As described, its use in a classical reverse flow manner allows the flap to reach only the metatarsophalangeal joints. The presence of the first dorsal interosseous pedicle offers the possibility to sacrifice the plantar anastomoses of the pedis pedicle and raise the flap on the vascular network of the first metatarsal space. The point of rotation is moved distally from the apex of the first metatarsal space to its base. The length of the vascular pedicle is substantially enhanced and enables the flap to cover all dorsal and palmar defects of the toes. Two clinical cases are showed. The advantages of this flap are discussed, particularly its indication in reconstructive surgery of the foot.
