肘管综合征的神经电生理检测价值

The effectiveness of electrophysiology in the diagnosis of cubital tunnel syndrome

目的探讨神经电生理检测对肘管综合征(CTS)的诊断价值。方法对临床诊断为肘管综合征的90例150侧患者测定:(1)第一背侧骨间肌、小指展肌及尺侧腕屈肌的肌电图(EMG)。(2)腕部、肘上5cm及肘下5cm尺神经运动传导时间及动作电位波幅,肘上5cm-肘下5cm、肘下5cm-腕部运动神经传导速度(MNCV)。(3)小指-腕部感觉神经传导速度(SNCV)等电生理检测,与30例正常人(对照组)的电生理数据进行分析比较。结果 CTS患者中第一背侧骨间肌出现正尖波及纤颤电位的分别为92侧及83侧,小指展肌出现正尖波及纤颤电位的分别为77侧及69侧,尺侧腕屈肌出现正尖波及纤颤电位的分别为36侧及28侧;CTS患者尺神经运动动作电位的波幅及传导时间、肘上5cm-肘下5cm及肘下5cm-腕部MNCV、小指-腕部SNCV与对照组比较差异均有极统计学意义(P<0.001)。结论神经电生理检测对CTS患者的诊断快捷、简便、对治疗提供客观依据。

Objective rTO investigate the effectiveness of electromyography in the diagnosis of cubital tunnel syndrome （CTS）. Methods The electrophysiological tests were conducted in 90 cases with clinical diagnosed cubital tunnel syndrome： （1） electromyography of first dorsal interrosseous muscle, abductor digital minimi muscle and flexor sharp uinaris muscle. （2） To measure the conducted time and amplitude of ulnar nerve （wrist, 5cm below the elbow and 5cm aboVethe elbow）, motor nerve collected. The data of EMG between the twO groups were compared and analyzed conduction velocity （MNCV） of ulnar nerve at 5cm below the elbow 5cm above the elbow and 5cm below the elbow-wrist, sensory nerves conduction velocity （SNCV） little finger.wrist .And the electrophysiological data of 30 healthy subjects were statistically, Results Positive sharp waves and fibrillation potentials weredetected in 92 and 83 UL, respectively, in first dorsal interrosseous muscle： were detected in 77 and 69 UL, respectively, in abductor digital minimi muscle; also collected, were detected in 36 and 28 UL, respectively, in the flexor sharp ulnaris muscle. There was a significant difference at conducted time, amplitude, MNCV and SNCV between CTS patients and normal controls （P〈0.001）. Conclusions Measurement of electrophysiology is a simple and quick technique of diagnosing CTS, thus providing a reliable evidence for treatment of CTS
