To determine the accuracy of the ultrasonographic measurement of ulnar nerve to cubital tunnel area for diagnosis of ulnar neuropathy at the elbow.
Patients with confirmed ulnar neuropathy at the elbow and normative, healthy volunteers were evaluated with high-resolution ultrasound. The cross-sectional areas (CSAs) of the ulnar nerve and cubital tunnel were measured with the elbow extended and flexed, and results from the 2 groups were compared.
Electromyography laboratory and radiology department of a tertiary care center.
Twenty-seven patients with ulnar neuropathy at the elbow and 20 controls.
Not applicable.
The ratio of ulnar nerve to cubital tunnel CSA with the elbow flexed.
The ulnar nerve, with the elbow flexed, was larger in those with ulnar neuropathy at the elbow, and this group also had larger cubital tunnels than did controls. In those with ulnar neuropathy at the elbow, the ratio of the ulnar nerve to cubital tunnel was .31, and in the controls it was .32, which was not significantly different (P=.89).
The ratio of ulnar nerve to cubital tunnel did not differentiate those with ulnar neuropathy at the elbow from controls.
确定超声测量尺神经至肘管区域用于诊断肘部尺神经病变的准确性。
对确诊为肘部尺神经病变的患者和正常健康志愿者进行高分辨率超声评估。在肘关节伸直和屈曲时测量尺神经和肘管的横截面积（CSA），并比较两组结果。
三级医疗中心的肌电图实验室和放射科。
27例肘部尺神经病变患者和20名对照者。
不适用。
肘关节屈曲时尺神经与肘管CSA的比值。
肘关节屈曲时，肘部尺神经病变患者的尺神经较大，且该组的肘管也比对照组大。肘部尺神经病变患者的尺神经与肘管比值为0.31，对照组为0.32，差异无统计学意义（P = 0.89）。
尺神经与肘管的比值不能区分肘部尺神经病变患者和对照组。
