ABSTRACT

Objective:To investigate the clinical effect of free fibular flap of great toe without vein in repairing soft tissue defect of finger pulp.Methods:From June 2020 to January 2021, 8 cases of finger pulp soft tissue defect were repaired with free flap of fibular side of great toe without vein, including 6 males and 2 females, with an average age of 32(18-42) years old. The defect area of finger pulp was 1.0 cm×0.5 cm-1.8 cm×0.8 cm. The proper digital artery and digital nerve of the affected finger were anastomosed. All flaps did not carry reflux veins. The donor site of the toe was directly sutured. Postoperative routine anti infection, anti spasm and anticoagulant treatment was performed. Postoperative outpatient regular follow-up.Results:All flaps survived without vascular crisis, and the donor and recipient sites healed in the first stage. All patients were followed-up for an average of 6.4(4-12) months. At the last follow-up, the TPD was 6-8 mm, the hand function was evaluated according to the Trial Standard of Upper Limb Function Evaluation of Hand Surgery Society of Chinese Medical Association. Seven cases were excellent and 1 case was good.Conclusion:The free fibular flap of the great toe can be used to repair the small wound of finger pulp without carrying the draining vein, the flap can still survive. And it can provide a certain reference for the failure of anatomic separation of the draining vein.
