肘管综合征的临床及神经电生理特点分析

An analysis of electrophysiological and clinical characteristics in patients with cubital tunnel syndrome

目的:探讨肘管综合征(CuTS)患者的临床及神经电生理特点。方法:总结56例(56肢)CuTS患者(患者组)的临床及神经电生理资料,并与50例正常人(对照组)相关的电生理数据进行分析比较。结果:尺神经运动传导速度肘上-肘下段为37.29±9.57 m/s,动作电位潜伏期较对照组延长、波幅降低,感觉神经传导速度为41.49±9.52 m/s,感觉电位潜伏期较对照组延长、波幅降低,其间的差异均有极显著意义(P<0.001)。患者组共有3例未引出运动诱发的动作电位波形。有8例未引出感觉诱发的动作电位波形。结论:神经电生理检测为诊断CuTS的可靠手段,可早期确诊及准确定位尺神经受损部位及损伤程度。

Objective：To investigate the clinical and electrophysiological characteristics in patients with cubital tunnel syndrome （CUTS）. Methods： The clinical and electrophysiological data in 56 patients with CuTS were collected. And the reletive electrophysiological data of 50 healthy subjects were also collected. The date of EMG in the two groups were compared and analyzed statistically. Results： The average conduction velocity of the ulnar nerve decreased, with motor conduction velocity （MCV） from above to below elbow 37.29±9.57 m/s and sensory conduction velocity （SCV） 41.49±9.52 m/s; the latency andamplitude of motor action potential was prolonged and decreased separately. The latency and amplitude of sensory action potential were prolonged and decreased separately. There was statistical difference between the patients group and the healthy control group （P〈0. 001）. The motor and sensory potentials could not he elicited in 3 and 8 of the 56 cases respectively. Conclusions： Electrophysiological examination could provide the reliable evidence for early diagnosis of CUTS, and the information for the exact location and degree of the ulnar nerve lesion.
