59例腕管综合征患者中有20例（34%）的正中神经和尺神经敏感性测试异常，包括两点辨别、Semmes-Weinstein单丝测试或两者兼而有之。术前，53%的患者主诉尺神经分布的感觉异常和/或麻木。80%的手部尺神经的塞姆斯-温斯坦单丝测试异常。35%的人有异常的两点分离。41%的患者尺神经肌电图检查异常。所有手均单独行正中神经减压术。Guyon的运河没有被释放。术后，89%的患者尺神经感觉异常和/或麻木得到改善。94%的患者在Semmes-Weinstein单丝测试中有改善。86%的人在两点辨别力方面有所改善。尺神经感觉残留异常的患者，正中神经感觉也持续异常。腕管综合征的患者中有很大一部分也有尺神经压迫的症状和体征。大多数改善与腕管单独释放。
Twenty of 59 hands (34%) of patients with carpal tunnel syndrome had abnormalities in sensibility testing of both median and ulnar nerves by either two-point discrimination, Semmes-Weinstein monofilament testing, or both. Before surgery, 53% of patients complained of paresthesias and/or numbness in ulnar nerve distribution. Eighty percent of the hands had abnormal Semmes-Weinstein monofilament testing of the ulnar nerve. Thirty-five percent had abnormal two-point discrimnation. Forty-one percent had abnormal electromyographic testing of the ulnar nerve. All hands had median nerve decompression alone. Guyon''s canal was not released. After surgery, 89% of patients had improvement in paresthesias and/or numbness of the ulnar nerve. Ninety-four percent had improvement in Semmes-Weinstein monofilament testing. Eighty-six percent had improvement in two-point discrimination. Patients with a residual abnormality in ulnar nerve sensibility also had continued abnormality in median nerve sensibility. A significant percentage of patients with carpal tunnel syndrome also have signs and symptoms of ulnar nerve compression. Most improved with carpal tunnel release alone.
