Longitudinally-split radial forearm flap

Abstract

We have applied the split flap concept to a distally-pedicled radial forearm flap to cover separate dorsal defects of the fingers in two cases. The rationale is that there are the vascular plexuses inside and around the sensory nerve that permit surgical splitting of the flap. In the split design, the first segment is supplied by the radial artery itself. The second segment is supplied by the neurocutaneous artery of the medial cutaneous nerve.
