In this study, we evaluated the ulnar nerve of patients diagnosed with carpal tunnel syndrome (CTS) using electrophysiology and ultrasonography.
The study included 86 patients (136 hands) and 39 controls (78 hands) with normal electrophysiological assessment. According to Bland's classification, patients were divided into group 1 (grades 1-3 CTS) or group 2 (grades 4-6 CTS). The ulnar nerve was evaluated at the wrist using nerve conduction studies and ultrasonography.
The sensory velocity was slower in group 2 than in group 1 (P < 0.001), slower in group 2 than in controls (P < 0.001), and slower in group 1 than in controls (P < 0.005). Although the ultrasonography results showed a reduction in the ulnar nerve cross-sectional area in group 1 compared with controls, the difference was not statistically significant. However, the reduction was significant in group 2 compared with group 1 and controls (P < 0.001).
Based on our study results, the ulnar nerve is affected electrophysiologically and morphologically in patients with CTS, especially those with advanced-stage CTS.
在本研究中，我们使用电生理学和超声检查对诊断为腕管综合征（CTS）的患者的尺神经进行了评估。
该研究纳入了86例患者（136只手）和39例对照者（78只手），这些对照者的电生理评估结果正常。根据布兰德分类法，将患者分为1组（1 - 3级CTS）或2组（4 - 6级CTS）。使用神经传导研究和超声检查在腕部对尺神经进行评估。
2组的感觉速度比1组慢（P < 0.001），2组比对照组慢（P < 0.001），1组比对照组慢（P < 0.005）。尽管超声检查结果显示1组的尺神经横截面积与对照组相比有所减小，但差异无统计学意义。然而，2组与1组及对照组相比，减小具有显著性（P < 0.001）。
基于我们的研究结果，CTS患者的尺神经在电生理和形态学上均受到影响，尤其是晚期CTS患者。
