Electrophysiological and clinical assessment of recovery of function was undertaken on 34 median and 33 ulnar nerve which had been resutured after complete section three and a half months to 24 years previously. An evaluation of different methods of repair was attempted. Our results suggested that re-exploration of the site of suture is indicated in the absence of voluntary activity on needle EMG by seven months (12 months for grafts), of an electrically evoked muscle action potential, measurable distal motor latency, or motor nerve conduction velocity by 10 months (14 months for grafts), or of clinically detectable voluntary muscle movement by 10 months after suture. By present techniques of repair useful prognostic information cannot be obtained by a consideration of sensory parameters either clinical or electrophysiological.
对34条正中神经和33条尺神经进行了功能恢复的电生理和临床评估，这些神经在3个半月至24年前完全离断后已进行了缝合。尝试对不同的修复方法进行评估。我们的结果表明，在缝合后7个月（移植为12个月）针电极肌电图无自主活动、10个月（移植为14个月）无电诱发肌肉动作电位、无可测量的远端运动潜伏期或运动神经传导速度，或10个月后无可临床检测到的自主肌肉运动时，提示需对缝合部位进行再次探查。就目前的修复技术而言，无论是临床还是电生理方面的感觉参数，均无法获得有用的预后信息。
