Abstract：Objective To explore the clinical effect of using the perforator muscle flap of the superficial peroneal artery to repair the wound of finger(toe)bone defect.Methods This study was a retrospective observational study.From April 2022 to July 2024,15 pa-tients with finger(toe)bone defect wounds who met the inclusion criteria were admitted to Suzhou Ruihua Orthopedic Hospital.There were a total of 15 wounds,including 9 finger wounds and 6 toe wounds;15 cases of bone defect wounds after injury,among which 8 cases were complicated with bone infection wounds.The wound area was 3.6 cm × 1.6 cm to 8.0 cm × 4.0 cm.The volume of the phalangeal defect ranges from 0.5 cm × 0.5 cm × 0.5 cm to 1.5 cm × 1.0 cm × 1.0 cm.The perforator muscle flap of the superficial peroneal artery was used to repair the wound,and the carried muscle was used to fill the bone defect cavity.The flap was harvested with an area of 5.0 cm × 2.0 cm to 12.0 cm × 4.5 cm,and the volume of the carried muscle was 1.5 cm × 1.0 cm × 0.5 cm to 5.0 cm × 2.0 cm × 1.0 cm.The donor sites of the flaps were all directly sutured.The survival of the flaps and the healing of the donor site wounds were observed after the operation.The oc-currence of infection was followed up.The clinical efficacy of the perforator muscle flap of the superficial peroneal artery was evaluated us-ing the flap comprehensive evaluation scale.Results All 15 perforator muscle flaps of the superficial peroneal artery survived smoothly;the donor sites healed in the first stage.During the follow-up period of 2 to 13 months,no recurrence of infection occurred in the bone de-fect wounds.The total score of the flap comprehensive evaluation scale was 100 points,and the scores of the 15 patients ranged from 71 to 93 points,with an average of 85 points.The comprehensive evaluation was excellent in 9 cases,good in 5 cases,and fair in 1 case,with an excellent and good rate of 93.3％.Conclusion The application of the perforator muscle flap of the superficial peroneal artery to repair the wound of finger(toe)bone defect can effectively fill the dead space and improve local blood circulation,reduce the recurrence of infection,cause less damage to the donor site,and achieve satisfactory therapeutic effects.
