Abstract:
Objective:To investigate the clinical effect of reconstruction of the degloving injury of thumb and finger with free perforator flap of superficial peroneal artery.Methods:This is a retrospective study. From June 2020 to June 2023, 18 superficial peroneal artery perforator flaps from 14 calves were used to treat 15 degloved digital wounds of 14 patients in the Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital. There were 13 single digital degloving wounds and 1 two-digital degloving wounds. Of which, 3 digits were reconstructed with 2 free perforator flaps of ipsilateral superficial peroneal artery and 12 with a single free perforator flap of superficial peroneal artery. The size of wounds was 4.0 cm×2.0 cm-10.0 cm×4.0 cm, and the flaps were 5.0 cm×3.0 cm-12.0 cm×4.0 cm in size. The donor sites in calves were sutured layer by layer with absorptive sutures. Postoperative follow-ups were conducted through regular outpatient visits, phone calls or WeChat. Survival of flaps, postoperative complications, therapeutic effect of the flaps and patient satisfaction were observed.Results:There was no vascular compromise or wound infection of the flaps. All patients were included in the 4 to 36 months of postoperative follow-up, with an average of 9.86 months. All flaps had good appearance, without obvious swelling. Colour and texture of the flaps was close to the surrounding skin. The flaps had no obvious pigmentation or ulcer and scar hyperplasia at recipient site. Sensation of the flaps recovered to S 2 to S 3. There was no obvious scar hyperplasia, pain or dysfunction at donor sites. According to the comprehensive evaluation scale of flap, the scores were found at 81 to 91, with an average score of 85 in the 14 patients, and of whom 2 were excellent and 12 were good. Patient satisfaction was evaluated according to the Michigan Hand Outcomes Questionnaire (MHQ) and 10 patients were very satisfied and 4 were satisfied. Conclusion:Free perforator flap of superficial peroneal artery is one of the ideal flaps in reconstruction of degloving injury of thumb and fingers. It features constant and multiple perforators, reliable blood supply, high survival rate, flexible in design, thin and a small damage to the donor site.
