Ulnar neuropathy at the elbow (UNE) is the second most common entrapment neuropathy. Our goal was to create and analyze a grading system for UNE electrodiagnostic severity.
We retrospectively analyzed EMG reports with UNE. We then classified 112 limbs as having mild, moderate, or severe grade UNE based on electrodiagnostic findings. The association between presenting symptoms and signs, EMG findings, treatment type, and electrodiagnostic grade was statistically analyzed.
Seventeen limbs (15.2%) had mild, 80 (71.4%) had moderate, and 15 (13.4%) had severe UNE. Symptoms (P = .016), exam findings (P < .001), and treatment type (P = .043) were significantly associated with electrodiagnostic grade.
Our UNE grading system was significantly related to symptoms, physical exam, and treatment selection and may be useful to measure electrodiagnostic severity.
肘部尺神经病变（UNE）是第二常见的嵌压性神经病。我们的目标是创建和分析用于UNE 电诊断严重程度的分级系统。
我们回顾性分析了有UNE 的肌电图报告。然后根据电诊断结果将 112 条肢体分为轻度、中度或重度UNE 级。对临床表现和体征、肌电图结果、治疗类型和电诊断分级之间的关系进行了统计学分析。
17 条肢体（15.2%）为轻度，80 条（71.4%）为中度，15 条（13.4%）为重度UNE。症状（P=0.016）、检查结果（P<0.001）和治疗类型（P=0.043）与电诊断分级显著相关。
我们的UNE 分级系统与症状、体格检查和治疗选择显著相关，可能有助于测量电诊断的严重程度。
