We studied the utility of ultrasound in the diagnostic workup of ulnar neuropathy with abnormal non-localizing electrophysiology (NL-UN) in patients with diabetes. Eighteen ulnar nerves (15 patients) were scanned from wrist to mid-upper arm. Ultrasound showed: (a) focal nerve enlargement at the elbow (8/18 nerves), either alone (6) or superimposed upon diffuse nerve abnormality (2); (b) diffuse nerve enlargement without focal abnormality (8/18); (c) segmental abnormality in upper-arm or forearm without extrinsic nerve compression (2/18). This study shows a pivotal role for ultrasound in the classification of NL-UN in patients with diabetes, which can facilitate critical therapeutic decisions.
我们研究了超声在伴有异常非定位电生理学（NL-UN）的糖尿病患者尺神经神经病诊断中的作用。对 15 名患者的 18 条尺神经从腕部到中上臂进行了扫描。超声显示：（a）肘部神经局灶性肿大（8/18 条神经），单独存在（6 条）或弥漫性神经病变合并存在（2 条）；（b）弥漫性神经肿大而无局灶性病变（8/18 条）；（c）无外在神经压迫的上臂或前臂节段性病变（2/18 条）。本研究表明，超声在糖尿病患者 NL-UN 的分类中具有重要作用，可以为关键的治疗决策提供依据。
