目的 探讨不同方式移植修复手指甲床缺损疗效。方法 选择2017年2月到2018年2月于本院收治手指甲床缺损患者60 例，按手术方式分为趾甲皮瓣修复、甲床移植、断层甲床移植三组。趾甲皮瓣修复组采用足趾甲皮瓣修复术，甲床 移植组采用吻合血管神经单纯游离趾甲床移植修复术，断层甲床移植组采用断层趾甲床移植修复术，3组患者术后 均随访8个月。在术后3个月、6个月、8个月分别评估术后患者患指功能恢复情况及患指修复情况，并统计3组患者 对修复效果的满意程度。结果 术后3个月、6个月、8个月，趾甲皮瓣修复组功能评分均高于甲床移植组、断层甲床 移植组(P＜0.05)；术后3个月、6个月、8个月，3组患者患指修复优良率无统计学意义(P＞0.05)；3组患者手术对 修复满意度差异无统计学意义(P＞0.05)。结论 足趾甲皮瓣携带感觉神经，故采用足趾甲皮瓣修复术治疗手指甲床 缺损利于手术患指功能恢复。

Objective To investigate the effect of different ways of repairing the defect of fingernail bed. Methods Sixty patients with fingernail defect in our hospital from February 2017 to February 2018 were enrolled. The patients were divided into three groups according to the surgical procedure: toe nail flap repair, nail bed transplantation and fault bed nail transplantation. Toe nail flap repair group was treated with toe nail flap repair. The nail bed transplantation group was treated with anastomosed vascular nerve simple toenail bed transplantation. The fault bed nail transplantation group was treated with fault toenail bed transplantation. All three groups were followed up for 8 times. Months. The recovery of the finger function and the repair of the finger were evaluated at 3 months, 6 months and 8 months after operation, and the satisfaction of the three groups was evaluated. Results At 3 months, 6 months, and 8 months after operation, the functional scores of the toenail flap repair group were higher than those of the nail bed transplantation group and the fault bed group(P<0.05); 3 months and 6 after operation. There was no significant difference in the rate of excellent finger repair between the three groups (P>0.05). There was no significant difference in the satisfaction of the three groups(P>0.05). Conclusion The toe nail flap carries sensory nerves. Therefore, the treatment of fingernail bed defects with toe nail flap repair is beneficial to the recovery of surgical finger function.
