Distally based perforator medial plantar flap: a new flap for reconstruction of plantar forefoot defects.

Abstract

In this article the author describes 2 cases of a distally based perforator medial plantar flap that were transferred successfully from the nonweight-bearing instep region to the weight-bearing plantar forefoot (defects, 8 x 5 cm and 6 x 5 cm respectively). This flap is nourished solely by perforators of the medial plantar vessels. The advantages of this flap are the protection of the vascular supply of the foot (because both posterior tibial and medial plantar vascular systems are preserved), anterograde flow of the vascular supply (which gives an additional advantage of expecting less venous insufficiency compared with reverse-flow flaps), no dependence on retrograde vascular communications, minimal donor site morbidity, and transport of structurally similar tissues to the plantar forefoot.
