The Application of Free Tissue Transfers to the Foot

During the past five years we have used three sources of free tissue transfers in 26 patients to reconstruct defects of the ankle and dorsum, hind, mid- and forefoot, defects poorly or unamenable to traditional reconstructive methods. These included free muscle transfers covered with a skin graft, temporoparietal fascia also covered with a graft, and radial forearm skin or fascia. In addition, six complex defects were reconstructed with composite tissue free transfers, usually tendinocutaneous flaps. There was one partial flap loss. All were successful in both healing the defect and in providing functional restoration, except in the forefoot. From an analysis of these cases, we have developed indications for various transfers based on the functional needs of the area involved and donor site requirements.
