Objective To evaluate the clinical results of free transfer of the digital artery dorsal branch flap for repairing fingertip defects.Methods Digital artery dorsal branch flap was transferred to repair fingertip defect in 21 cases.The digital artery dorsal branch was anastomosed to the proper digital artery of the recipient site; the digital nerve dorsal branch included in the flap was coapted with the proper digital nerve of the recipient site while the superficial veins were anastomosed as well.Donor site of the flap was located on the radiodorsal or ulnodorsal aspect of the proximal segment of either the injured finger or the adjacent finger.Donor site defect was covered with full-thickness skin graft.Results All 21 flaps survived.Postoperative follow-up time ranged from 6 to 12 months,with an average of 8 months.The texture and appearance of the flaps were satisfactory.Finger movement was good.Two-point discrimination of the flaps recovered to 5 to 10 mm.Skin grafts at the donor site healed well,with no ulceration and wearing in the long term.Donor finger movement was not impaired.Conclusion Digital artery dorsal branch flap free transfer is an ideal procedure to treat fingertip defect.It leads to near normal appearance and good sensory recovery of the repaired finger.
