回顾性分析了36例外伤性臂丛神经损伤合并C5神经根损伤的病例。我们使用胆碱乙酰转移酶（CAT）活性测量作为可修复性的金标准指标，以评估传统技术（术前临床、电生理和放射学检查以及术中临床和电生理检查）的可靠性。我们提出了一个可修复性评分系统组成的相关的常规技术，并使用相同的参考技术（CAT活性测量）测试该评分系统的有效性。我们发现C5皮区感觉和肌电图研究与C5可修复性之间无显著相关性。另一方面，我们发现Tinel征、脊髓造影、宏观和显微镜检查以及电刺激与C5可修复性显著相关。基于这些结果，我们提出了一个简单的21点评分系统来评估C5神经根的可修复性，该系统由Tinel征、脊髓造影、宏观和微观外观以及电刺激组成。评分系统被认为是高度显着相关的C5修复。我们的结论是，我们提出的评估评分系统是一个可靠的方法C5的可修性评估，它可以取代复杂的技术。
We reviewed 36 traumatic brachial plexus injury patients with C5 nerve root injury. We used the choline acetyltransferase (CAT) activity measurement as a gold standard indicator of repairability to assess the reliability of the conventional techniques (preoperative clinical, electrophysiologic, and radiologic examination and intraoperative clinical and electrophysiologic examinations). We proposed a repairability scoring system composed of the correlated conventional techniques and tested the validity of this scoring system using the same reference technique (CAT activity measurement). We found no significant correlation between sensation at C5 dermatome and electromyography study with C5 repairability. On the other hand, we found a significant correlation of Tinel sign, myelography, macroscopic and microscopic examination, and electrical stimulation with C5 repairability. Based on these results, we propose a simple 21-point scoring system to evaluate the repairability of C5 nerve root that is composed of Tinel sign, myelography, macroscopic and microscopic appearance, and electrical stimulation. The scoring system was found to be highly significantly correlated with C5 repairability. We concluded that our proposed evaluation scoring system is a reliable method for C5 repairability evaluation, and it can replace sophisticated techniques.
