From April 1984 to March 1994, 31 reconstructive thumbs or fingers were followedup, including 16 cases with free neurovascular big toe nail skin flap and frozen preserved phalanxjointtendon composite allografts as well as 15 cases withfree second toe transfer. The method had the advantage of more fingers could bereconstructed and fewer toes would be lost. The decision of the site of reconstruction of finger, the augmentation of narrow web space between the thumb and the index finger, the prevention and treatment of vascular crisis and the degeneration of allogenic joint were discussed. It had been found that preserving the allogenic finger below -30℃ may lower the immunoreaction of the allogenic tissues. It was emphasized that the viable tissues should be preserved during the emergency debridement, so as to facilitate the following reconstruction procedure.
