Objective:To explore the clinical effect of cosmetic reconstruction for partial defect of distal segment of digits.Methods:Form January 2018 to January 2021, the Department of Hand Surgery of Institute for Hygiene of Ordnance Industry(The 521 Hospital of Weapon Industry) admitted 129 patients with partial defect of distal segment of thumb or fingers with phalange or tendon exposure. The patients were 111 males and 18 females with an average age of 34(17-59) years old. The sizes of nailbed defect were 0.4 cm×1.1 cm-1.8 cm×2.0 cm, the length of phalange defect was 0.4-1.8 cm, and the sizes of the soft tissue defect were 1.6 cm×1.8 cm-3.2 cm×4.8 cm. Great toe tissue flaps were used to reconstruct the partial defect of distal segment of thumb or fingers after debridement. Wounds of fibular flap of great toe in 77 cases were directly sutured in 17 patients. The donor sites in rest 60 great toes were narrowed first and then repaired with skin grafts in 10 cases, with artificial dermis in 28 cases and with transverse V-Y advancement flaps of ipsilateral great toes for 22 cases. Forty-nine of 52 donor site wounds for hallux toenail flap were repaired with artificial dermis and 3 with free peroneal artery perforator flaps. The method was outpatient follow-up. Postoperative follow-up lasted until July 2022. The check-items for follow-up included: occurrence of necrosis, appearance, shape and texture of the flap, appearance of the reconstructed nails, TPD of the reconstructed digit pulps, tolerance to cold on the scars of flaps, flexion and extension of the reconstructed digits. The healing time of phalanges of the reconstructed digits was evaluated by X-rays. The appearance, sensation, the tolerance to cold of great toe and the movement of donor foot were also assessed.Results:Postoperative follow-up lasted for 18 to 24 months, with an average of 21 months. A total of 128 flaps survived. Necrosis occurred in 1 fibular hallux flap, the necrosis was cured with a reverse digital proper artery island flap. Thereafter, all flaps healed well. The appearance, shape, texture and nails of reconstructed digits were close to the contralateral digits. The reconstructed thumb and finger were evaluated according to Zook, 127 cases were excellent and 2 cases were good.TPD of the pulps of the reconstructed digits was 4-10 mm. The mean score of the Vancouver scar scale(VSS) was 0.6 for scars of the reconstructed digits. The mean score of the Visual analog scale(VAS) was 0.3 for the tolerance to cold. Flexion and extension function recovered well in all the reconstructed digits. According to the Evaluation Criteria of Upper limb Function Hand Surgery Society of Chinese Medical Association, the function of hand was excellent in 127 cases and 1 in each of good and fair. X-rays of all digits showed the phalange healing of the reconstructed digits, with an average healing time of 2 months after surgery, without phalange resorption, infection, nonunion nor stress fracture. There was no difference between the length of the donor great toe and the contralateral toe, except the donor site of the great toe nail root. There was no significant visual difference between the appearance of the donor great toe and the contralateral toe. TPD of the pulps of donor great toe was 4-8 mm. The mean score of the VSS was 1.4 for scars in the donor great toe. The mean score of the VAS was 0.7 for the tolerance to cold of the donor great toe. There was no stress fracture at donor site, and the functions of donor foot were not affected when walking, running, jumping and tiptoeing in all patients.Conclusion:It is an ideal method for reconstructing a partial defect of distal segment of digit by great toe flap. It can not only reconstruct the partial defect of distal segment of the digit, but also results in a good appearance and satisfactory functions of the reconstructed digit. Damage to the donor site is minimum. The length of the donor great toe is unchanged, and it has little impact on sensation and appearance of the donor great toe. Meanwhile, there is no adverse effect on walking, running and jumping with the donor foot.

First, the donor site of the fibular hallux flap was sutured to reduce the size of wound. The width of the remaining wound was 0.4 to 1.6 cm, and the area of the remaining wound was 0.5 cm×0.8 cm-1.6 cm×1.8 cm. Then the remaining wound was repaired with the transverse V-Y advancement flap of the ipsilateral great toe. The distance for transfer of transverse advancement V-Y flap was 0.2-0.8 cm, and the area of the transverse V-Y advancement flap was 1.0 cm×1.4 cm-1.8 cm×2.4 cm. The end of postoperative follow-up was scheduled in July 2021. The follow-up items included: survival of the transverse V-Y advancement flap, wound infection, appearance, shape, texture and sensation of the V-Y advancement flap, pain on the V-Y advancement flap and the great toe, cold tolerance and the scar condition at the donor site of the ipsilateral fibular hallux flap and the V-Y advancement flap, the appearance, sensation and flexion and extension of the great toe at the donor site, other discomforts in the donor site of great toe, walking and other functions affected by the discomforts.Results:The postoperative follow-up lasted from 12 to 18(average of 14) months. All the V-Y advancement flaps survived without infection at the donor sites of the great toe, and donor sites healed primarily. The appearance, shape and texture of the advancement V-Y flap were close to the skin of the same area of the contralateral great toe. The TPD of the V-Y advancement flap and the ipsilateral great toe ranged from 4 to 7 mm. The average score of the Visual analog scale(VAS) was 0.3 and 0.6 respectively in the evaluation of cold tolerance of the advancement V-Y flap and the ipsilateral great toe. The average score of the Vancouver scar scale(VSS) was 0.2 and 1.2 respectively in the scar evaluation of the V-Y advancement flap and the ipsilateral great toe. There was no visual difference between the appearance of the great toe at the donor site and the contralateral toe. There was no pain and other discomfort on the V-Y advancement flap and the ipsilateral great toe. The functions of the donor foot were not affected in walking, running, jumping and tiptoeing in all cases.Conclusion:It is a simple, safe and effective method to repair the donor site of the small-area ipsilateral fibular hallux flap by the transverse V-Y advancement flap of the great toe. It only causes a small wound but the appearance and function of the ipsilateral great toe can be repaired with a transverse V-Y advancement flap of the great toe.
