Nail bed reconstruction is crucial after fingertip trauma, impacting both function and aesthetics. In this article, the authors describe a case of partial distal phalanx amputation of the index finger with laceration of the nail bed's remaining part. A traumatically elevated skin-fat flap covered the exposed bone on the fingertip, preserving finger length and sensitivity on the radial side. A full-thickness skin graft from the forearm closed a secondary defect on the finger pulp. Nail bed suturing prevented scarring and nail deformity, and a temporary artificial plastic nail replacement maintained the nail bed's shape. Temporary artificial nail replacements protect the regenerating fingertip bed, promote healing, and prevent nail deformities. Proper adaptation of lacerated nail bed edges, supported by either the patient's own nail or a temporary artificial nail, is crucial for optimal fingertip restoration, including proper nail shape.
指尖创伤后，甲床重建至关重要，这不仅影响功能，还影响美观。本文作者介绍了 1 例食指末节部分指骨离断伴甲床残端撕裂伤的病例。通过创伤性掀起皮瓣脂肪瓣覆盖指尖外露的骨质，既保留了手指长度，又保留了桡侧的敏感性。从前臂取全厚皮片覆盖指腹的二期缺损。甲床缝合防止了瘢痕和指甲畸形，临时人造塑料指甲替代物维持了甲床的形状。临时人造指甲替代品保护再生的指尖床，促进愈合，并防止指甲畸形。正确适应撕裂的甲床边缘至关重要，无论是患者自身的指甲还是临时人造指甲都可以支持，这对于最佳的指尖修复至关重要，包括适当的指甲形状。
