The aim of this study was to determine the value of high-resolution ultrasound (HRUS) in patients with ulnar neuropathy whose electrophysiology displayed an axonal, non-localizing pattern.
A prospective study of patients referred to an electromyography laboratory for ulnar neuropathy was performed. Of the 56 patients with clinical and electrodiagnostic (EDx) evidence of ulnar neuropathy, 12 were identified with non-localizing electrophysiology who subsequently underwent HRUS of the ulnar nerve.
HRUS localized the ulnar neuropathy in all patients. In 2 patients, HRUS demonstrated structural lesions not at the elbow.
HRUS often adds complementary information to standard EDx studies, including ulnar neuropathy. Thus, HRUS should be employed in patients with a non-localizing ulnar neuropathy on EDx studies. Muscle Nerve 58: 655-659, 2018.
本研究旨在确定在电生理学显示轴索性、非局灶性模式的尺神经病变患者中，高分辨率超声（HRUS）的价值。
对因尺神经病变而被转至肌电图实验室的患者进行前瞻性研究。在 56 例具有临床和电诊断（EDx）证据的尺神经病变患者中，有 12 例被确定为非局灶性电生理学，随后对这些患者进行 HRUS 检查。
HRUS 对所有患者的尺神经病变进行了定位。在 2 例患者中，HRUS 显示了肘部以外的结构性病变。
HRUS 通常为标准 EDx 研究（包括尺神经病变）提供补充信息。因此，对于 EDx 研究中显示非局灶性尺神经病变的患者，应采用 HRUS。肌肉神经 58：655-659，2018 年。
