Clinical application of the free superficial palmar branch of radial artery flap for soft-tissue reconstruction of distal digital injury

Abstract

Abstract Purpose The purpose of this study is to retrospect and summarize clinical efficiency and experience of the free superficial palmar branch of radial artery (SPBRA) flap for soft-tissue reconstruction in distal digital injury. Method 13 patients with soft-tissue defect of finger, reconstructed by the free superficial palmar branch of radial artery (SPBRA) flap in our department from January 2020 to January 2022, were reviewed. After 6–12 months of follow-up, evaluated the treatment effect of the fingers reconstructed by SPBRA flap. Results All the flaps in our series application were survival uneventful, and all the donor sites were closed primarily without complications or obvious scarring. The flaps were soft in texture and satisfactory in appearance and function. The flaps with the median nerve palmar cutaneous branch had a good sensation recovery. Measurement of two-point discrimination (TPD) ranged from 6 to 10 mm. All patients were satisfied with the aesthetic appearance. According to the Evaluation Trial Standards of Upper Limb Partial Function of Hand Surgery of Chinese Medical Association, the results were graded as excellent in 11 cases and good in 2 cases. Conclusion The SPBRA perforator flap has the advantages of simple operation, soft texture, good appearance and function, and is credible and useful for reconstructing various finger injuries.
