The purpose of this article is to introduce the results of thumb and finger
reconstruction using transplantation of the big toe wraparound flap combin
ed with the second toe or the second and third toes. Between August of 1981
and December of 1998, in a series of 64 cases involving 58 patients with d
igitless hands, either (1) the thumb and index fingers were reconstructed b
y transplantation of a big toe wraparound flap combined with the adjacent s
econd toe harvested from the ipsilateral foot; or (2) the thumb, index, and
long fingers were reconstructed by transplantation of an ipsilateral big t
oe wraparound flap combined with the adjacent second and third toes. The ph
alanx of the new thumb was usually an iliac block. The success rate of this
series was 92.2 percent. At long-term followup, the average static 2-point
discrimination was less than 10 mm. The distance between the tip of the ne
w thumb and the new index finger ranged from 6 to 10 cm (average, 8 cm). op
position action was nimble and forceful. The patients could lift a 6- to 12
-kg weight with their reconstructed digits. All patients were satisfied wit
h their new hands and were able to use them in their daily activities. The
transplants for reconstructing the thumb and fingers are harvested from the
same foot in a procedure known as one-foot donation. Function of the bilat
eral digitless hand can be recovered with this procedure.
