Avulsed defect of a fingernail bed is a common injury in acute hand trauma. Insufficient management for this type of nail bed avulsion often leads to an irregular and nonadherent nail. The use of thin split-thickness sterile matrix graft from the great toe for immediate replacement of a nail bed defect can regain a smooth, adherent, and normal-looking nail. Between May of 1998 and December of 2001, we used thin split-thickness toenail bed grafts in 13 fingers of 12 patients with avulsed defects of the nail bed. The end results of this technique were excellent and no deformities occurred in the graft donor area. Thin split-thickness toenail bed graft is a good choice for the treatment of acute nail bed avulsion.
指甲床撕脱伤是急性手部创伤中的常见损伤。对这类指甲床撕脱伤处理不当常导致指甲不规则且不附着。采用取自拇趾的薄断层无菌甲床移植片立即修复指甲床缺损，可使指甲恢复光滑、附着且外观正常。1998年5月至2001年12月期间，我们对12例指甲床撕脱伤患者的13根手指采用了薄断层趾甲床移植术。该技术的最终效果极佳，且移植供区未出现畸形。薄断层趾甲床移植术是治疗急性指甲床撕脱伤的理想选择。
