摘　　要：目的探讨肘管综合征的神经电生理特点及手背尺侧皮神经在其中的应用价值。方法选取2021年1月至2023年1月就诊于本院的61例肘管综合征患者为研究对象,其中单侧肘管综合征51例(累及右侧25例、左侧26例),双侧肘管综合征10例,受检尺神经71条。同时检测61例患者(71手)的手背尺侧皮神经,分析其神经电生理特点。结果71条尺神经中65条尺神经跨肘段神经传导速(MCV)减慢,异常率91.6%;36条尺神经肘以上复合肌肉动作电位(CMAP)波幅降低,异常率50.7%;48条尺神经F波潜伏期延长,异常率67.6%;51条尺神经(腕-小指)感觉传导检测异常,异常率71.8%。71条手背尺侧皮神经中61条感觉传导检测异常,异常率达85.9%,与尺神经跨肘段异常率相仿,差异无统计学意义(P>0.05)。结论尺神经跨肘段MCV是评价肘管综合征的敏感指标,可明确受累部位,判断损伤程度,手背尺侧皮神经在诊断及鉴别诊断中有重要指导意义。Objective To investigate the neuroelectrophysiological characteristics of cubital tunnel syndrome and the application value of ulnar cutaneous nerve on the dorsal hand.Methods A total of 61 patients with cubital tunnel syndrome who were admitted to Zhoushan Hospital from January 2021 to January 2023 were selected as the research objects.There were 51 cases of unilateral cubital tunnel syndrome(right side 25 cases,left side 26 cases),bilateral cubital tunnel syndrome in 10 cases,71 ulnar nerves were examined.Meanwhile,the dorsal ulnar cutaneous nerve of the hand was detected in 61 patients(71 hands).The neuroelectrophysiological characteristics were analyzed.Results The MCV of 65 ulnar nerves across the elbow was slowed down,and the abnormal rate was 91.6%.The CMAP amplitude of 36 ulnar nerves above the elbow was decreased,and the abnormal rate was 50.7%.The latency of F wave was prolonged in 48 ulnar nerves,with an abnormal rate of 67.6%.51 ulnar nerve(carp-little finger)sensory conduction tests were abnormal,with an abnormal rate of 71.8%.Sensory conduction abnormalities were detected in 61 of 71 dorsal ulnar cutaneous nerves,with an abnormal rate of 85.9%,which was similar to the abnormal rate of ulnar nerve across the elbow,and the difference was not statistically significant(P>0.05).Conclusion MCV of ulnar nerve across cubital tunnel syndrome is a sensitive index for the evaluation of cubital tunnel syndrome,which can identify the involved site and judge the degree of injury.The ulnar cutaneous nerve of dorsal hand has important guiding significance in the diagnosis and differential diagnosis.
