[Thumb and finger reconstruction with the pedal digit transplantation: 541 cases report].

Thumb and finger reconstruction by the method of pedal digit transplantation had been successfully performed in 541 casee from 1977 to 1996, which contained 404 cases of thumbs and 78 cases of fingers. The thumb reconstruction was mainly the simple transplantation of distal phalanx (42 cases) and the compound transplantation of hallucal nail-cutaneous flap with iliac bone segment (16 cases) for the defect of thumbs in degree 1 and 2. The combined transplantation of hallucal nail-cutaneous flap with the joint and tendons of the second toe (34 cases) and the transplantation of the distal part of the second toe (182 cases) for the defect of degree 3 and 4. The combined transplantation of the second pedal digit with its metatarsalphalangeal joint (189 caese) for the defect in degree 5 and 6. The finger reconstruction was performed by anastomosis of the arteries of the digit with those of the fingers for 29 cases with the defect in degree 2 and 3, 60 cases with the defect in degree 4 and 5, and 17 cases with the defect in degree 6. One-hundred and four cases of versels vasiation were found in this group (19 cases with the pedal dorsal artery, 13 cases with the greater saphenous vein and 72 cases with the first dorsal metatarsal artery). The main point of the operation and the treatment of the vessel variations were discussed.
