Alternative techniques for pedicle transfer of an island flap and a free flap.

Alternative techniques for pedicle transfer of a reverse radial forearm flap for hand coverage, and a latissimus dorsi myocutaneous free flap for pelvic wound coverage, are illustrated. Exteriorization of the vascular pedicle of a reverse radial forearm flap allows a greater arc of movement of the flap for more distal coverage, and avoids the potential vascular compromise of tunnelling under a tight skin bridge. Two-stage transfer of a latissimus dorsi myocutaneous free flap on a wrist carrier pedicle may be useful in circumstances when local recipient vessels are inadequate for free flap transfer. Although both of these vascular pedicle modifications have drawbacks, they may be of value in limited circumstances. Their advantages and limitations are discussed.
