目的:探讨第1趾蹼皮瓣修复足趾软组织缺损的方法。方法:设计以第一跖背动脉为血管蒂的皮瓣,转移修复3例足远端三度烧伤伴肌腱及骨外露创面。皮瓣切取面积为2cm×3cm～3cm×5cm。皮瓣蒂宽1.0～2.5cm。结果:3例皮瓣均完全成活,1例供瓣区皮片坏死,经换药后愈合。术后经6～10个月随访,皮瓣质地柔软,外形良好,感觉存在,行走满意。结论以第一跖背动脉为血管蒂的皮瓣具有良好的血运,操作方便,可恢复感觉功能,是修复足部远端软组织缺损的良好方法。 Objective: To investigate the method of repairing the soft tissue defects of the toes with the first toe flap. Methods: The flap of the first metatarsal dorsal artery was designed as a vascular pedicle, and 3 cases of third-degree distal burn accompanied with tendon and bone-exposed wounds were repaired. Flap cut area of ​​2cm × 3cm ~ 3cm × 5cm. Pedicle pedicle width 1.0 ~ 2.5cm. Results: All three flaps survived completely. One of the flaps was necrosis and was healed after dressing change. After 6 to 10 months of follow-up, the skin texture is soft, the appearance is good, the feeling exists and the walking is satisfactory. Conclusion The flap pedicled with the first dorsal metatarsal artery has a good blood supply, which is convenient for operation and regains sensory function. It is a good method to repair soft tissue defects in the distal part of the foot.
