Methods Based on using the first plantar/dorsal metatarsal artery, or toe artery as pedicle to cut off partial toenail together with toe abdomen flap or partial toenail to repair 64 cases which include 69 fingers with distal segment complete and partial defect, the distal skin avulsion, skin tube in postoperative plastic, replantation failure and so on. Depending on the size of the donor foot wound use the first dorsal metatarsal artery, second toe artery, the perforating branch of peroneal artery or plantar metatarsal artery flap to cover the wound, and then observe the appearance of the finger and foot donor site after operation. Results The finger pulp was full and elastic, nail bed of the toe was well heal- ing, nail groove which originated from the reconstructed nail fold was shallow, the appearance was realistic, all feelings were recovery, two-point discrimination was 4 to 5 millimeter, the donor toe was plump like the original one in appearance, patients were all satisfied with the reconstructed finger and the toe shape, after a follow-up from 3 month to 4 years.
