Abstract：Objective To investigate the effect of slowly widening the distal great toe on improving the shape and function of the donor site in finger reconstruction.Methods A retrospective study was conducted on two patients who underwent widening of the distal great toe before finger reconstruction in Shandong Provincial Hospital Affiliated to Shandong University between September 2020 and August 2021. A 19-year-old male patient with grade Ⅱ defect of the right middle finger underwent widening of the distal great toe in the first stage and full reconstruction of the right middle finger with free osteo-onychocutaneous flap in the second stage. A 36-year-old female patient with grade V defect of the right middle finger simultaneously underwent widening of the distal great toe and lengthening of the right middle finger in the first stage and then full reconstruction of the right middle finger with free osteo-onychocutaneous flap in the second stage. The donor site was repaired by delayed full-thickness skin transplantation. The patients were followed up for 3-6 months after reconstruction. The healing of the phalanges, the survival of the reconstructed fingers, and the appearance and function of the great toes were evaluated.Results The reconstructed fingers of the two patients survived with primary bone healing and without nonunion or postoperative vascular crisis. The width of the toenail at the donor site was approximately normal, and the great toe had satisfactory appearance and normal function.Conclusions The slow widening of the distal great toe can preserve the appearance and function of the donor site, particularly toenail width, for patients who need finger reconstruction.
