Abstract:
Objective:To explore the effects of the second dorsal metacarpal artery perforator flap relaying the dorsal island flap of index finger in repairing thumb wounds.Methods:The study was a retrospective observational study. From May 2021 to January 2023, 14 patients with thumb wounds who met the inclusion criteria were admitted to Gansu Provincial People's Hospital, including 8 males and 6 females, aged 24 to 63 years. After debridement, the wound area was 2.1 cm×1.2 cm to 5.5 cm×3.5 cm. The dorsal island flap of index finger with incision area of 2.4 cm×1.5 cm to 5.5 cm×3.5 cm was used to repair the thumb wound, and then the second dorsal metacarpal artery perforator flap with incision area of 2.7 cm×1.6 cm to 5.7 cm×3.6 cm was cut through the same incision to repair the donor wound in the index finger, and the donor wound in the dorsal of hand was directly sutured. The survival of flap was observed, and the healing of the donor wound in the dorsal of hand was observed after operation. The condition of donor wound in the dorsal of hand, the color, appearance, and texture of flap, postoperative complications, return to work, and satisfaction with the treatment effect of patients were followed up. At the last follow-up, the function of the thumb and the index finger was evaluated with the trial standards for evaluation of partial function of upper extremity by the Hand Surgery Society of Chinese Medical Association.Results:After operation, all flaps survived, and the donor wounds on the back of the hands healed. During follow-up of 6-12 months, only linear scars remained on the donor wounds in the dorsal of hands, and the color of flaps was similar to that of the surrounding normal skin, with a full appearance and soft texture. There were no complications such as scar tenderness or scar contracture in any patient. All patients had normal sensation in the thumb and index finger, resumed normal work, and were satisfied with the treatment effects. At the last follow-up, the function of thumb and index finger was evaluated as excellent in 9 cases and good in 5 cases.Conclusions:The second dorsal metacarpal artery perforator flap can repair the thumb wound by relaying the dorsal island flap of index finger, without damaging the major blood vessels, with only linear scars remained on the donor wounds in the dorsal of hands after operation, with good appearance of flap and function of thumb and index finger. The operation is relatively simple with good clinical effects.
