Ulnar neuropathy at the elbow (UNE) involves mechanical compression and irritation of the ulnar nerve (UN) caused by environmental and dynamic abnormalities that can however also be found in asymptomatic patients. Using high-resolution ultrasound, we aimed to assess and compare the relevance of morphological and dynamic variants of the UN and its surrounding structures (UN abnormalities) in symptomatic and asymptomatic patients.
UN abnormalities in patients with UNE were assessed using high-resolution ultrasound and compared against unaffected arms (patients or healthy volunteers).
We studied 234 arms of 117 individuals (89 with UNE and 145 control). Eighty-one percent of the arms with UNE compared to 40% of control (p=0.00001) showed UN abnormalities. While it was dislocated in 49% of arms with UNE compared to in 23% of control (p=0.004).
The two-fold higher frequency of occurrence of UN abnormalities in arms with UNE indicates their causative or at least contributory role in such neuropathies. High-resolution ultrasound should be part of the initial evaluation of UNE in order to assess the etiology of the conflict.
肘管尺神经病变（UNE）是由环境和动态异常引起的尺神经（UN）机械性压迫和刺激所致，但也可在无症状患者中发现。我们使用高分辨率超声来评估和比较有症状和无症状患者 UN 及其周围结构（UN 异常）的形态和动态变异的相关性。
使用高分辨率超声评估 UNE 患者的 UN 异常，并与未受影响的手臂（患者或健康志愿者）进行比较。
我们研究了 117 个人的 234 只手臂（89 只患有 UNE 和 145 只对照）。与对照组（40%）相比，UNE 组中 81%的手臂存在 UN 异常（p=0.00001）。而在 UNE 组中，UN 脱位的比例为 49%，而在对照组中为 23%（p=0.004）。
UNE 手臂中 UN 异常的发生率高出两倍，表明其在这些神经病变中具有病因或至少有促成作用。高分辨率超声应该成为 UNE 初始评估的一部分，以评估冲突的病因。
