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.
目的: 探讨抗生素骨水泥直接诱导皮肤再生技术修复足趾侧方皮瓣供区创面的可行性和临床效果。.
方法: 2020年6月—2023年2月，应用抗生素骨水泥直接诱导皮肤再生技术修复10例11处足趾侧方皮瓣供区创面。其中男7例，女3例；年龄21～63岁，平均40.6岁。均为手指指腹皮肤缺损，其中拇指末节3例，示指末节2例，示、中指中节1例，中指末节1例，环指末节3例。手部皮肤软组织缺损范围2.4 cm×1.8 cm～4.3 cm×3.4 cm。病程1～15 d，平均6.9 d。皮瓣供区位于踇趾腓侧5处，第2足趾胫侧5处，第3足趾胫侧1处。足趾侧方皮瓣范围为2.5 cm×2.0 cm～4.5 cm×3.5 cm。11处皮瓣供区创面均不能直接缝合，其中2处有肌腱外露；均采用抗生素骨水泥覆盖。.
结果: 10例患者均获随访，随访时间6个月～2年，平均14.7个月。11处皮瓣全部成活且皮瓣外形较好。足部供区创面均愈合，愈合时间40～72 d，平均51.7 d。供区无明显瘢痕，与周围正常皮肤色泽相近；供足外观良好，穿鞋、行走功能未受影响。.
结论: 采用抗生素骨水泥直接诱导皮肤再生技术修复足趾侧方皮瓣供区创面可行，创面能自行愈合，且操作简便，无第2供区损伤。.
