Objective  To discuss the effectiveness of free toe fibular-dorsal artery flap anastomosed to dorsal digital artery in repairing dorsal soft tissue defect of fingers. Methods  Between May 2010 and September 2015, 28 patients with dorsal soft tissue defect of fingers were treated, including 17 males and 11 females with an average age of 23.8 years (range, 15-55 years). The reasons of injuries were machine twist (15 cases), heavy pound (4 cases), the sharp cut (5 cases), and hot crush (4 cases). The time from injury to admission was 30 minutes to 12 hours (mean, 1.5 hours). The involved fingers included thumb (3 cases), index finger (8 cases), middle finger (6 cases), ring finger (6 cases), and little finger (5 cases). The area of soft tissue defects ranged from 2.0 cm×1.5 cm to 3.5 cm×2.5 cm, and the area of free toe fibular-dorsal artery flap ranged from 2.8 cm×1.7 cm to 3.8 cm×2.8 cm. The blood supply of the flaps were reconstructed by anastomosing the toe fibular-dorsal artery, vein, and nerve to the dorsal digital artery, vein, and nerve, respectively. The donor site was repaired by free skin graft. Results  The operation time was 1.5-5.5 hours (mean, 2.5 hours); the blood loss during operation was 10-50 mL (mean, 30 mL). Vessel crisis occurred in 1 case, and the flap survived after symptomatic treatment. The other flaps survived and the wounds healed with stage I; the skin grafts at donor site survived and the incisions healed with stage Ⅰ. Twenty-eight cases were followed up 6-24 months (mean, 8 months). The appearance of flaps was good, and two-point discrimination was 3.5-12.0 mm (mean, 5.3 mm) at 6 months after operation. The fingers function of grab and pinch recovered. According to the standard functional evaluation issued by Hand Surgery Association of Chinese Medical Association, the results were excellent in 20 cases and good in 8 cases, with an excellent and good rate of 100% at 6 months after operation. The donor sites of toe were smooth and had no depression. The patients had normal gait. Conclusion  Free toe fibular-dorsal artery flap anastomosed to dorsal digital artery in repairing dorsal soft tissue defect of fingers can obtain satisfactory effectiveness in appearance and function of fingers, and has the advantages of modified repair and less injury at donor site.
