Free Medial Plantar Artery Perforator Flaps for the Resurfacing of Thumb Defects

Abstract

The MPAP flap is a suitable choice for reconstructing palmar defects of the fingers, with less donor site morbidity. The cushiony character of the MPAP flap is anatomically similar to the pulp tissue of fingers, and sensory restoration is ideal compared with that of other reconstructive methods. Technical difficulty is focused on anastomosis of perforators (diameter ≤0.8 mm).
