BACKGROUND
Ulnar neuropathy at the elbow (UNE) is the second commonest entrapment neuropathy after carpal tunnel syndrome (CTS) and yet the laterality is not well delineated. Our aim was to establish the laterality of UNE in a large cohort of patients.
METHODS
All new patients with clinical and electrodiagnostic (EDX) confirmed UNE over a 13-year period were included. We used multivariate analysis to examine potential predictors of laterality, and unilateral vs bilateral UNE.
RESULTS
Of 880 cases, 61% were left-sided and 39% right-sided. These proportions did not change regardless of the handedness of the patient. Patients with bilateral UNE were much more likely to be older male and have a variety of comorbidities.
CONCLUSIONS
UNE appears to be present on the left 50% more often than on the right, regardless of the patient's handedness.
背景
肘部尺神经病变（UNE）是继腕管综合征（CTS）之后第二常见的嵌压性神经病，但侧别尚不清楚。我们的目的是在一大群患者中确定 UNE 的侧别。
方法
在 13 年的时间里，我们纳入了所有新诊断的临床和电诊断（EDX）确诊的 UNE 患者。我们使用多变量分析来检查侧别和单侧与双侧 UNE 的潜在预测因素。
结果
880 例患者中，61%为左侧，39%为右侧。无论患者的惯用手如何，这些比例都没有改变。双侧 UNE 的患者更可能是年龄较大的男性，且合并多种合并症。
结论
UNE 似乎更常发生在左侧，其发生率比右侧高 50%，而与患者的惯用手无关。
