OBJECTIVE: To investigate the effectiveness of the modified great toe fibular flap using the distal artery pedicle as reflux vein for repairing distal phalanx finger wound. METHODS: Between June 2018 and January 2020, 15 patients who suffered tissue defect of the distal phalanx finger were treated, including 12 males and 3 females, the average age was 40.2 years (range, 24-56 years). All of them were caused by machine crush injury. There were 2 cases of thumb, 6 cases of index finger, 3 cases of middle finger, 3 cases of ring finger, and 1 case of little finger. The defects ranged from 1.7 cm×1.3 cm to 3.0 cm×2.0 cm. The time from injury to admission was 0.6-4 hours, with an average of 2.3 hours. The medial fibular proper digital artery was further dissociated to the distal end and anastomosed with the recipient vein as the reflux vein. The area of flaps ranged from 2.0 cm×1.5 cm to 3.2 cm×2.2 cm. RESULTS: All the flaps survived without vascular crisis, and the wounds healed by first intention. Except for 1 case that the suture was too tight, the incision was partially split after the stitches were removed, and it healed spontaneously after dressing change, the other patients had good healing of the donor site incision and normal foot function. All 15 patients were followed up 3-18 months, with an average of 9.3 months. The appearance of finger pulps were satisfactory with full and threaded. The color, texture, and elasticity of the flaps were good, and the two-point discrimination was 6-8 mm at last follow-up. The flexion and extension of fingers were normal. At last follow-up, hand function was evaluated according to the upper limb function evaluation trial standard of the Chinese Medical Association Hand Surgery Society, and the results were 13 cases of excellent and 2 cases of good. CONCLUSION: Modified great toe fibular flap using the distal arterial pedicle as a reflux vein can improve the venous drainage of the flap and contribute to increase the success rate of the flap without additional injury.
