Factors that predispose patients to ulnar mononeuropathy at the elbow (UME) are poorly defined. We compared 112 electrodiagnostic reports which met criteria for definite or probable UME to 104 reports which excluded UME. Male gender was strongly associated with definite (OR = 6.9, 95% CI = 2.4-20.4; P < 0.001) and all UME (OR = 2.2, 95% CI = 1.2-4.1; P = 0.010) after controlling for age and body mass index (BMI). Among men, UME was associated with increasing age (P = 0.008) but not a decreased BMI. Women, however, demonstrated an association between decreased BMI and UME (OR = 2.3, 95% CI = 1.3-4.2 for BMI < or =22.0 versus >22.0). These findings, in conjunction with gender differences in ulnar motor nerve parameters among UME subjects and controls, suggest that the pathophysiology of UME differs with gender.
导致患者发生肘部尺神经单神经病（UME）的因素目前尚不清楚。我们将112份符合明确或可能UME标准的电诊断报告与104份排除UME的报告进行了比较。在控制年龄和体重指数（BMI）后，男性与明确的UME（比值比[OR]=6.9，95%置信区间[CI]=2.4-20.4；P<0.001）以及所有UME（OR=2.2，95%CI=1.2-4.1；P=0.010）密切相关。在男性中，UME与年龄增长相关（P=0.008），但与BMI降低无关。然而，女性中，BMI降低与UME相关（BMI≤22.0与>22.0相比，OR=2.3，95%CI=1.3-4.2）。这些发现，连同UME患者和对照组之间尺神经运动神经参数的性别差异，表明UME的病理生理学因性别而异。
