The evolution of the pedicled radial forearm flap

Because of the thin skin envelope of the hand, especially at the dorsum, flaps are frequently required for defect reconstruction in the hand. The pedicled radial forearm flap is a time proven procedure that offers reliable coverage in this area without the need of advanced microsurgical expertise. Despite several alternatives and an increasing acceptance of free tissue transfers, the pedicled radial forearm flap can still be the procedure of choice under special circumstances. Variations of the original technique address the two main disadvantages, the conspicuous donor site and the sacrifice of the radial artery. Indications, anatomy, surgical technique, and limitations of this classic workhorse flap are presented.
