Repair of fingertip defect with free second toe tibial flap anastomosed by the dorsal nerve of the toe / 中华整形外科杂志

ABSTRACT

Objective@#To report the operation methods and clinical effects of repairing finger tip defect with the free tibial dorsal nerve flap of the second toe.@*Methods@#13 patients with finger tip defects were repaired by the tibial dorsal nerve flap of the second toe. The area of finger tip defect was 2.5 cm×1.5 cm-1.3 cm×1.0 cm, and the area of cutting flap was 2.7 cm×1.7 cm-1.5 cm×1.1 cm. All donor site defects on the second toe were covered with full-thickness skin graft.@*Results@#There were 13 cases in this group, and all the flaps and skin grafts were survived. Postoperative follow-up ranged from 6 to 18 months, with an average of 13 months. The appearance of the fingers was satisfied and the sensory recovery was good. Two-point discrimination of the flaps returned to 7-13 mm, with an average of 9 mm. According to the total active move(TAM)scale, results were excellent in 11 fingers, good in 1 finger, and fair in 1 finger. The donor site skin graft was well healed, the second toe pulp was full, and the two-point discrimination of the toe pulps were 6-10 mm, with an average of 8 mm.@*Conclusions@#Compared to the traditional method of repairing finger tip defect with the tibial inherent nerve flap of the second toe, our new method can reduce the damage to the donor site, and we can repair finger tip defect as well as the traditional one at the same time. So it was a better operative method to repair finger tip defect with the tibial dorsal nerve flap of the second toe.
