A new flap, the reverse medial planter island flap based on the distal end of the medial plantar artery (MPA) is introduced. It is found that the MPA is connected with the plantar profund artery via the first plantar metatarsal artery or the big lateral branch of the MPA, joining the common digital artery that comes from the arch of the plantar artery. This flap was used in 3 cases of electric injury with satisfactory results. It suggests that the reverse medial plantar island flap is an ideal flap for reconstruction of the defects in the weight-bearing area of the forefoot.
