48例肘管综合征临床分析

Clinical analysis on 48 cases of 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46例CuTS患者患侧(患者组)与健侧(对照组)相关的临床及神经电生理资料进行分析比较。结果尺神经运动传导速度肘上-肘下段为(33.56±8.61)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(37.34±8.57)m/s,感觉电位潜伏期较对照组延长,波幅降低,其间的差异均有统计学意义(P<0.05)。患者组1例未引出运动诱发的动作电位波形,4例未引出感觉诱发的动作电位波形。结论肘管综合征应早诊断、早治疗;而神经电生理检测为诊断肘管综合征的可靠手段,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 Clinical and electrophysiological data in 46 patients with CuTS were collected. And the results were compared with the healthy limbs of the 46 patients. Results The average conduction velocity of the ulnar nerve decreased, with motor conduction velocity（MCV） from above to below elbow （33.56 ± 8. 61）m/s and sensory conduction velocity （SCV） （37.34±8.57）m/s; the latency and amplitude of motor action potential was prolonged and decreased separately. There was statistical difference between the patients group and the healthy control group（P〈0.05）. The motor and sensory potentials could not be elicited in I and 4 of the 46 cases respectively, Conclusion The cubital tunnel syndrome should be diagnosed and treated early. 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.
