Objective  To investigate the feasibility and effectiveness of antibiotic bone cement directly inducing skin regeneration technology in the repairing of wound in the lateral toe flap donor area. Methods Between June 2020 and February 2023, antibiotic bone cement directly inducing skin regeneration technology was used to repair lateral toe flap donor area in 10 patients with a total of 11 wounds, including 7 males and 3 females. The patients’ age ranged from 21 to 63 years, with an average of 40.6 years. There were 3 cases of the distal segment of the thumb, 2 cases of the distal segment of the index finger, 1 case of the middle segment of the index and middle fingers, 1 case of the distal segment of the middle finger, and 3 cases of the distal segment of the ring finger. The size of the skin defect of the hand ranged from 2.4 cm×1.8 cm to 4.3 cm×3.4 cm. The disease duration ranged from 1 to 15 days, with an average of 6.9 days. The flap donor sites were located at fibular side of the great toe in 5 sites, tibial side of the second toe in 5 sites, and tibial side of the third toe in 1 site. The skin flap donor site wounds could not be directly sutured, with 2 cases having exposed tendons, all of which were covered with antibiotic bone cement. Results All patients were followed up 6 months to 2 years, with an average of 14.7 months. All the 11 flaps survived and had good appearance. The wound healing time was 40-72 days, with an average of 51.7 days. There was no hypertrophic scar in the donor site, which was similar to the color of the surrounding normal skin; the appearance of the foot was good, and wearing shoes and walking of the donor foot were not affected. Conclusion It is a feasible method to repair the wound in the lateral foot flap donor area with the antibiotic bone cement directly inducing skin regeneration technology. The wound heals spontaneously, the operation is simple, and there is no second donor site injury.
