Injury:臂丛神经损伤部位和致伤原因无关

2012-11-26 MedSci Injury

臂丛神经损伤对个体而言是灾难性的,可能导致严重的上肢功能障碍。单纯临床体检评估不足以判断臂丛神经损伤的节段和严重性,而对损伤节段和严重性的精确判断有利于临床医生更好的预测损伤的功能预后,目前已经有较为精确的电生理测量仪器如肌电图,神经传导速度测试仪等设备帮助临床医生对臂丛神经损伤进行节段和严重性的评估。近期印度学者对百余例臂丛损伤的患者进行了电生理学检测分析,借以明确臂丛损伤程度、节段和创伤类型的

臂丛神经损伤对个体而言是灾难性的,可能导致严重的上肢功能障碍。单纯临床体检评估不足以判断臂丛神经损伤的节段和严重性,而对损伤节段和严重性的精确判断有利于临床医生更好的预测损伤的功能预后,目前已经有较为精确的电生理测量仪器如肌电图,神经传导速度测试仪等设备帮助临床医生对臂丛神经损伤进行节段和严重性的评估。近期印度学者对百余例臂丛损伤的患者进行了电生理学检测分析,借以明确臂丛损伤程度、节段和创伤类型的相互关系,结论发表在injury杂志上。
研究共纳入111例患者,其中1例患者为双侧臂丛神经损伤(表1)。共106里男性,5例女性。采用电生理测量仪器,应用Dumitru’s and Wilbourn’s评分标准对臂丛神经损伤的严重程度进行评分:轻度为1分,中度为2分,重度为3分。

表1:入选患者的人口统计学数据

研究结果显示:道路交通伤(road traffic crash,RTCs)是臂丛神经损伤最为常见的因素,其余各项因素见图1;锁骨上神经损伤最为多见,其次是锁骨下损伤,锁骨上下均损伤较为少见,神经损伤区域分布如图2,表2;神经损伤的严重程度和受伤类型关系如表3。

图1:臂丛神经损伤的原因分布

图2:臂丛神经损伤的区域分布

表2:不同原因的臂丛神经损伤节段分布

表3:不同原因臂丛神经损伤节段和严重程度分布

研究者据数据得出结论,摩托车祸伤是臂丛神经损伤最为重要的原因;锁骨上区域神经损伤是最常见的损伤类型;在进行临床诊断时需要区分臂丛神经损伤程度;臂丛神经损伤原因和损伤节段无明显相关性。
