Abstract Objective To analyze and compare the effect of dorsal branch chain flaps of digital artery with proximal and middle segments as donor sites in repairing fingertip defects of the homodigital finger.Methods A retrospective analysis was performed on 48 patients (48 fingers) with defects of the 2nd to 5th fingertips admitted to the Second Hospital of Tangshan from February 2016 to August 2020.Dorsal branch chain of proximal phalangic artery flaps were used in 26 fingers of 26 cases，including 17 males and 9 females.The age ranged from 18 to 55 years，with a mean ago of (36.5±10.9) years.Dorsal branch chain of middle knuckle finger artery flaps were used in 22 fingers of 22 cases，including 14 males and 8 females.The age ranged from 20 to 54 years，with a mean ago of (35.8±10.7) years.Age，gender，wound size，operation time，follow-up time，skin flap appearance satisfaction，static two-point discrimination，total range of motion of injured knuckles and postoperative donor site appearance were compared between the two groups.Results All flaps survived successfully after operation.The follow-up time was 12 to 20 months.There were no significant differences in age，sex，wound size，operation time，follow-up time and total range of motion of injured digits between the two groups (P＞0.05).The satisfaction of flap appearance，static two-point discrimination，and postoperative appearance of donor site of patients in the middle segment donor site group were better than those in the near segment donor site group，and the differences were statistically significant (P＜0.05).Conclusion The dorsal branch-chain flaps of digital artery with the skin of the proximal and middle segments as the donor site is a simple operation with reliable blood supply.It is suitable for repairing soft tissue defects of the homodigital fingertip.Compared with the proximal donor site flap，the dorsal branch-chain flaps of digital artery with the middle segment as the donor site has more beautiful in appearance，less scar in the donor site，and better postoperative sensory recovery.
