摘要:

单侧指神经损伤后常会发生从未损伤指神经向损伤侧长入的交叉神经支配现象,关于其是否会影响指神经外科修复的临床结局,目前尚无定论。我们试图通过一项对比单侧与双侧损伤指神经修复效果的回顾性临床研究,了解交叉神经支配是否会影响指神经修复的临床结局。试验纳入19例2年内单侧或双侧指神经损伤患者,对其28处指神经损伤进行端侧缝合法修复。所有患者均接受至少12个月的随访,通过Weber两点辨别觉、锐-钝器触碰辨别觉、温冷觉和视觉模拟评分评估指神经感觉恢复情况。结果发现,虽然存在交叉神经支配现象,但单侧或双侧指神经修复患者感觉功能恢复程度无明显差异。说明在评估指神经外科缝合临床结局的时候可以忽略交叉神经支配现象。

Abstract: Digital nerve injuries are the mostly detected nerve injury in the upper extremity. However, since the clinical phenomenon of crossover innervation at some degree from uninjured digital nerve to the injured side occurs after digital nerve injuries is sustained, one could argue that this concept might even result in the overestimation of the outcome of the digital nerve repair. With this knowledge in mind, this study aimed to present novel, pure, focused and valuable clinical data by comparing the outcomes of bilateral and unilateral digital nerve repair. A retrospective review of 28 fngers with unilateral or bilateral digital nerve repair using end-to-end technique in 19 patients within 2 years was performed. Weber’s two-point discrimination, sharp/dull discrimination, warm/cold sensation and Visual Analog Scale scoring were measured at final 12-month follow ups in all patients. There was no significant difference in recovery of sensibility after unilateral and bilateral digital nerve repairs. Though there is crossover innervation microscopically, it is not important in the clinical evaluation period. According to clinical fndings from this study, crossover innervations appear to be negligible in the estimation of outcomes of digital neurorrhaphy.
