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 discrimination. 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.
59例腕管综合征患者中，有20只手（34%）通过两点辨别觉、Semmes-Weinstein单丝试验或两者进行的正中神经和尺神经感觉测试出现异常。术前，53%的患者主诉尺神经分布区有感觉异常和/或麻木。80%的手尺神经Semmes-Weinstein单丝试验异常。35%两点辨别觉异常。41%尺神经肌电图检查异常。所有手均仅行正中神经减压术，未松解Guyon管。术后，89%的患者尺神经感觉异常和/或麻木症状改善。94%的患者Semmes-Weinstein单丝试验改善。86%的患者两点辨别觉改善。尺神经感觉仍有残留异常的患者，正中神经感觉也持续异常。相当比例的腕管综合征患者也有尺神经受压的体征和症状。大多数患者仅行腕管松解术即可改善。
