INTRODUCTION
In the precise localization of ulnar neuropathy at the elbow (UNE) we have noted discrepancies between electrodiagnostic (EDx) and ultrasonographic (US) findings. We aimed to explore the relationship between the 2 techniques.
METHODS
Four study-blind examiners took a history and performed neurologic, EDx, and US examinations of a group of prospectively recruited patients with UNE. They assessed the relationship between ulnar nerve cross-sectional area (CSA) and motor nerve conduction velocity (MNCV).
RESULTS
In 106 patients with UNE at the retrocondylar (RTC) groove, the highest CSA and lowest MNCV were noted in the same short segment. In 54 patients with UNE at the humeroulnar aponeurosis (HUA), the highest CSA and lowest MNCV were noted proximal to the HUA.
DISCUSSION
MNCV and CSA were highly correlated in UNE. Ulnar nerve slowing proximal to the entrapment at the HUA was surprising, but consistent with previous studies done on carpal tunnel syndrome. Muscle Nerve 56: E65-E72, 2017.
引言
在肘部尺神经病变（UNE）的精确定位中，我们注意到电诊断（EDx）和超声检查（US）结果之间存在差异。我们旨在探讨这两种技术之间的关系。
方法
四位对研究不知情的检查者对一组前瞻性招募的UNE患者进行病史采集，并进行神经学、EDx和US检查。他们评估了尺神经横截面积（CSA）与运动神经传导速度（MNCV）之间的关系。
结果
在106例髁后（RTC）沟处UNE患者中，最高CSA和最低MNCV出现在同一短节段。在54例肱尺腱膜（HUA）处UNE患者中，最高CSA和最低MNCV出现在HUA近端。
讨论
在UNE中，MNCV和CSA高度相关。HUA处卡压近端尺神经减慢令人惊讶，但与先前关于腕管综合征的研究结果一致。《肌肉与神经》56: E65-E72, 2017年。
