Abstract Objective To investigate the clinical effect of dorsal metacarpal artery perforator flap in repairing deep finger injuries.Methods From June 2018 to October 2021, 86 cases of finger injuries complicated with tendon and/or bone exposure were selected from the Burn and Plastic Surgery Department of the 910th Hospital of Chinese PLA Joint Service Support Force. They were divided into a study group and a control group, with 43 cases in each group according to surgical methods. The study group was repaired with a dorsal metacarpal artery perforator flap, while the control group was treated with an abdominal flap. The number of surgeries, wound healing time, and hospitalization time of the two groups were observed. After discharge, the patients were followed up for 10-12 months to observe the appearance, texture, and skin temperature of the flaps. Hand function was evaluated using TAM in both groups of patients.Results The number of operations in the study group (1.2±0.4) was significantly less than that in the control group (2.5±0.6). The wound healing time [(15.2±3.4) d] and hospitalization time [(18.3±4.6) d] in the study group was significantly shorter than those in the control group [(26.6±4.8) d and (29.5±6.8) d]. Follow-up visit for 10-12 months showed that the flap in the study group had a more similar texture to the wound margin and a less bulky appearance compared with the control group. In the control group, 12 cases had a bulky appearance and were admitted to the hospital for a second stage flap thinning surgery 6 months after surgery. After 12 months of wound healing, the evaluation of hand function in the study group was excellent in 35 cases, good in 6 cases, and moderate in 2 cases. The evaluation of hand function in the control group was excellent in 23 cases, good in 10 cases, and moderate in 10 cases.Conclusions The application of dorsal metacarpal artery perforator flap for deep finger wound repair is characterized by positive effects, fewer times of operation, quicker recovery and good appearance and function recovery.
