目的：探讨高频超声在肘管综合征诊断中的作用。方法选取肘管综合征患者25例（25肘）及正常对照组50例（50肘），行超声检查并比较尺神经厚度、CSA ，用ROC曲线评价超声诊断肘管综合征标准值的准确性。结果超声可显示尺神经损伤后的形态学变化及提示病因，患病组近端尺神经厚度及CSA均大于正常组，两组比较差异有统计学意义。CSA及CSA肿胀率的诊断阈值分别为0．087 cm2、146％。结论超声对尺神经的形态学变化具有重要的诊断价值。

Objective To assess the value of ultrasonographic in diagnosis of cubital tunnel syndrome . Methods 25 patients (25 wrists)and 50 cintrols (50 wrists) .The maximal cross -sectional areas(CSA) ,the maximal diameter in short were measured and comparaed between two groups .The accuracy of the ultrasono-graphic diagnostic criteria for cubital tunnel syndrome was evaluated using receiver operating characteristic (ROC) analysis .Results US displayed changes and some etiological factors of cubital tunnel syndrome .The measurements of ulnar nerve at the proximal part of the compression were higher than those in the control group .All measurement showed significant differerces between patients and controls .The cut -off point of CSA and CSA tumefaction ratio was 0 .0 8 7 cm2 and 1 4 6% .Conclusion US has important morphological reference value in the diagnosis of cubital tunnel syndrome .
