    Abstract
  •   Objective   To investigate the effects of miniature free groin perforator flaps in repairing small wounds on hands.   Methods   The retrospective observational study was conducted. Fifteen patients with 16 small wounds on hands were admitted to Tongren Hospital of Wuhan University & Wuhan Third Hospital from July 2020 to October 2022, including 12 males and 3 females, aged 19 to 56 years. The size of skin and soft tissue defect was 2.0 cm×1.5 cm to 6.0 cm×3.0 cm after debridement. According to size and shape of the wounds, 13 single-lobe perforator flaps and 2 bilobed perforator flaps were designed in the groin region, with the flap size of 4.5 cm×2.5 cm to 7.5 cm×3.5 cm. According to the condition of the recipient area, the arteries and veins at the pedicle of the flap were anastomosed to the arteries and veins of the recipient area respectively. The wounds in the donor area of the flap was closed by layered and tension-reducing suture. The thickness of the flap was measured during operation. The survival of the flap was observed, and the complications in the donor and recipient areas were recorded after operation. The appearance and texture of the flap were observed during follow-up. At the last follow-up, the sensory recovery of the affected hand was evaluated, the function of the affected hand was evaluated according to the trial standard of the upper limb partial function evaluation of the Hand Surgery Society of the Chinese Medical Association, the scar in the donor and recipient areas were observed, and the satisfaction of patients for the curative effects was inquired.   Results   The thickness of the flap was ranged from 0.3 to 1.0 cm, with an average thickness of 0.6 cm. After operation, 11 single-lobe flaps and 2 bilobed flaps survived well; in the left 2 single-lobe flaps, one flap had venous crisis but returned to normal after removing stitches to reduce tension and bloodletting of flaps, while the other one flap had a little necrosis on tip but healed after dressing change. No complications occurred in donor and recipient areas. During follow-up of 8 to 35 months after operation, the flaps had good elasticity and soft texture; 8 flaps were slightly bloated and were trimmed 3 to 8 months after operation, while the appearances of the other flaps were good. At the last follow-up, all flaps recovered protective feeling; the function of the affected hand was evaluated as excellent in 10 cases, good in 4 cases, and fair in 1 case; only linear scar remained in the donor and recipient areas; the patients were satisfied with the appearance and function recovery of the affected hand.   Conclusions   The miniature free groin perforator flaps in repairing small wounds on hands have the advantages of high survival rate of flaps, hidden flap donor area, little damage, few complications, good repair effect, etc., showing clinical application value. It is recommended for repairing non-functional wounds on hands.
