摘要
本研究旨在探讨利用可生物降解的几丁质导管同时修复损伤神经的效果。近正中神经作为供体神经修复远正中神经和整个尺神经。术后4个月，中尺神经远端髓鞘轴突数目和神经传导速度分别为(2085±215和24.4±5.9 m/s)和(1193±102和30.7±11.2 m/s)。还观察了再扭转肌肉的强直性肌力的恢复。提示Dor - to - Dor+Rec神经缝合术是治疗严重周围神经损伤的一种实用方法。
Can "dor to dor+rec neurorrhaphy" by biodegradable chitin conduit be a new method for peripheral nerve injury?
This study aims to estimate the effects of using one donor nerve to repair the injured nerve and itself simultaneously by biodegradable chitin conduit. Proximal median nerve served as donor nerve to repair the distal median and whole ulnar nerve. Four months postoperation, the number of myelinated axons and nerve conduction velocities of the distal median and ulnar nerve were (2085 ± 215 and 24.4 ± 5.9 m/s), and (1193 ± 102 and 30.7 ± 11.2 m/s). Recovery of the tetanic muscle forces of the reinvervated muscles were also observed. It suggests that Dor to Dor+Rec neurorrhaphy is a practical method for severe peripheral nerve injury.
