【摘要】：目的:本研究通过建立正中神经在腕管入口与出口处横截面积的比值,阐明其对腕管综合征的诊断价值。方法:46个经临床检查和电生理检测确诊的腕管综合征患者和44个健康志愿者均进行腕部超声检测。分别在腕管入口(舟骨-豌豆骨水平)和腕管出口(钩骨钩水平)处测量正中神经的横截面积,并计算相应的入口与出口处横截面积的比值。超声检测和电生理检查在双盲条件下进行。电生理检测结合相应的临床症状被认为是诊断腕管综合征的金标准。用ROC曲线来评价此比值的诊断准确性。结果:实验组:16男,30女(平均45.3岁,18-83岁)。对照组:18男,26女(平均50.4岁,18-79岁)。正中神经腕管入口处的横截面积实验组和对照组分别为为14.6 mm2和8.7 mm2(P0.001)。对照组面积比为1.0,小于实验组中的面积比1.6(P0.001)。ROC曲线分析表明面积比的诊断价值优于入口处横截面积(P0.001)。当面积比取值为1.3时,诊断的特异度和敏感度分别为93%和91%。结论:正中神经在腕管入口与出口处横截面积的比值是一种诊断腕管综合征的有效方法,但是需要大规模的随机对照试验进一步研究。
[Abstract]:Objective: to clarify the diagnostic value of the median nerve at the transverse area of the carpal tunnel entrance and the outlet of the carpal tunnel. Methods: 46 patients with carpal tunnel syndrome and 44 healthy volunteers were examined by clinical examination and electrophysiological examination. The transverse area of the median nerve was measured at the exit of the carpal canal (the hook level of the carpal hook) and the ratio of the corresponding cross section of the entrance to the exit was calculated. The ultrasonic detection and electrophysiological examination were carried out under double blindness. The electrophysiological tests combined with the corresponding clinical symptoms were considered as the gold standard for the diagnosis of carpal tunnel syndrome. The ROC curve was used to evaluate this. The diagnostic accuracy of the ratio. Results: the experimental group: 16 men and 30 women (average 45.3 years, 18-83 years old). The control group was 18 men and 26 women (average 50.4 years, 18-79 years old). The experimental group and the control group were 14.6 mm2 and 8.7 mm2 (P0.001) at the median nerve carpal tunnel entrance. The area ratio of the group was 1, and the area ratio of the experimental group was compared to 1.6 (P0.001).ROC koji. Line analysis shows that the diagnostic value of area ratio is better than that of the transversal area of the entrance (P0.001). When the area ratio is 1.3, the specificity and sensitivity of the diagnosis are 93% and 91%., respectively. The ratio of the median nerve at the entrance of the carpal tunnel and the exit is an effective method for the diagnosis of carpal tunnel syndrome, but it requires a large random pair. Further study was carried out according to the test.
