Application of different types of free foot flaps in hand surgery.

Abstract

From 1987, nine types of free vascularized flaps or combined flaps from the foot were used to treat 26 cases of hand injury with tissue loss. They were: (1) combined flap of 4 toe dorsums, big toe pulp, first toe web, and dorsalis pedis flap with long extensor tendons of the toes, (2) composite skin flap with the second metatarsophalangeal joint, (3) wrap-around flap from the great toe, (4) first toe web flap, (5) toe pulp flap with only an artery and a nerve, (6) wrap-around flap of the great toe with a dorsalis pedis flap, (7) second toe with dorsalis pedis flap, (8) dorsalis pedis flap, and (9) first toe web flap with second metatarsal bone. All flaps survived. All the patients have used their reconstructed hand. Of the final motor functions of the reconstructed hands, 68.8% are excellent, 27.3% are good, 3.9% are fair. Of the final cosmetic results of the reconstructed hands, 76.9% are excellent, 15.3% are good, 7.8% are acceptable. Of the patients, 64.9% are satisfied with the final results of the donor sites, 31.2% feel it is acceptable, and 3.9% feel it is unsatisfactory. The selection, indication, merits and demerits of vascularized foot flaps and attentive points in the operations are discussed in this paper.
