Upper Limb Salvage Using a Free Radial Forearm Flap

Microsurgical transfer of a skin flap salvaged from a nonreplantable upper extremity that would otherwise be discarded may provide essential soft-tissue coverage of the amputation stump, so maintaining a functional range of motion in the elbow joint. A radial forearm free flap measuring 24 cm long by 9 cm wide was salvaged from the degloved forearm skin of a patient who sustained a proximal forearm amputation that was considered unsuitable for replantation. This allowed coverage of the proximal radius and ulna, preservation of a functional elbow joint, and successful fitting of a below-elbow prosthesis.
