摘要：

目的 采用神经电生理学方法探讨腕管综合征（CTS）与尺神经腕部卡压的相关性。方法 选择20例（22腕）CTS患者（CTS组）和20名（20腕）健康成年志愿者（对照组），测量并比较两组正中神经和尺神经感觉传导速度、运动传导速度、感觉远端潜伏期和运动远端潜伏期，计算并比较正中神经与尺神经感觉远端潜伏期差值，对CTS组正中神经与尺神经感觉传导速度行Pearson相关分析。结果 与对照组比较，CTS组正中神经感觉和运动传导速度及尺神经感觉传导速度均较慢（P<0.05或P<0.01），尺神经感觉远端潜伏期较长（P<0.05）；两组尺神经运动传导速度及其运动远端潜伏期比较差异无统计学意义（P>0.05）；CTS组正中神经与尺神经感觉远端潜伏期差值显著大于对照组（P<0.05）。Pearson相关分析显示：CTS组正中神经与尺神经感觉传导速度呈显著正相关（r=0.802，P=0.002)。结论 CTS与尺神经腕部卡压存在相关性，对CTS患者诊治时应充分考虑尺神经卡压并存的可能性。

Abstract:

Objective To investigate the relationship between carpal tunnel syndrome (CTS) and ulnar nerve entrapment at wrist with neural electrophysiological methods. Methods Twenty patients (22 wrists) with CTS (CTS group) and 20 healthy adults (20 wrists) (control group) were selected. Sensory conduction velocity, motor conduction velocity, distal sensory latency and distal motor latency of median nerve and ulnar nerve were measured and compared between two groups, and the differences in distal sensory latency between median nerve and ulnar nerve were calculated and compared between groups. Pearson correlation analysis was performed between sensory conduction velocity of median nerve and that of ulnar nerve in CTS group. Results Compared with control group, the sensory conduction velocity and motor conduction velocity of median nerve and the sensory conduction velocity of ulnar nerve were slower （P<0.05 or P<0.01），and the distal sensory latency of ulnar nerve were longer in CTS group （P<0.05）. There was no significant difference in the motor conduction velocity and distal motor latency of ulnar nerve between two groups （P>0.05）. The difference in distal sensory latency between median nerve and ulnar nerve in CTS group was significantly larger than that in control group （P<0.05）. Pearson correlation analysis revealed that the sensory conduction velocity of median nerve was significantly positively related to that of ulnar nerve in CTS group （r=0.802，P=0.002). Conclusion There is correlation between CTS and ulnar nerve entrapment at wrist, and ulnar nerve entrapment at wrist should be attached great importance when dealing with patients with CTS.
