【摘要】：目的:研究应用高频超声对腕横韧带厚度、腕管断面积与腕管内容物断面积之比进行定量测量,分析诊断阈值、敏感度、特异度,为超声诊断腕管综合征增加敏感性、特异性。方法:选取2010年10月-2013年5月门诊患者组(CTS)26例35侧,经电生理及临床症状确诊,对照组健康志愿者30例60侧,年龄性别与患者组匹配。高频超声测量豌豆骨水平及钩骨钩水平腕横韧带厚度、腕管断面积与腕管内容物断面积之比,所有计量资料以“均数±标准差”表示,采用两样本均数的t检验,P0.05有统计学意义。根据所得测量指标采用spss13.0软件绘制ROC曲线,测定各测量指标的诊断阈值,计算敏感度与特异度。并比较腕横韧带厚度与断面积比值之间的相关性。结果:豌豆骨水平腕横韧带厚度最佳截点值取0.295cm时,灵敏度为74.3%,特异度为86.7%。豌豆骨水平腕管断面积与腕管内容物断面积比值取最佳截点值2.44时,灵敏度为61.7%,特异度为77.1%。钩骨钩水平腕管断面积与腕管内容物断面积比值取最佳截点值2.447,灵敏度为83.3%,特异度为62.9%。腕横韧带厚度与断面积比值呈负相关性。结论:高频超声可以清晰显示腕管壁及腕管内神经、肌腱等结构回声,通过结合定量指标测量,可准确诊断腕管综合征,并可明确病因情况,为临床选择治疗方式及时机提供有效帮助。
[Abstract]:Objective: to study the quantitative measurement of the thickness of the transverse carpal ligament and the ratio of the broken area of the carpal tunnel to the broken area of the carpal tunnel by high-frequency ultrasound, and to analyze the diagnostic threshold, sensitivity and specificity, so as to increase the sensitivity and specificity of ultrasound in the diagnosis of carpal tunnel syndrome. Methods: from October 2010 to May 2013, 26 patients (35 sides) with (CTS) in outpatient group and 30 healthy volunteers (60 sides) in the control group were confirmed by electrophysiological and clinical symptoms. The thickness of transverse carpal ligament and the ratio of broken area of carpal tunnel to contents of carpal tunnel were measured by high frequency ultrasound. All the measured data were expressed as "mean 卤standard deviation". Using the t test of the mean of two samples had statistical significance. Spss13.0 software was used to draw the ROC curve according to the measured indexes. The diagnostic threshold of each measurement index was measured and the sensitivity and specificity were calculated. The correlation between the thickness of transverse carpal ligament and the ratio of broken area was compared. Results: the sensitivity and specificity of 0.295cm were 74.3 and 86.7, respectively. The sensitivity was 61.7 and the specificity was 77.1 when the ratio of horizontal carpal tunnel area to carpal tunnel content was 2.44. The ratio of horizontal carpal tunnel area to carpal tunnel content was 2.447, sensitivity was 83.3 and specificity was 62.9. There was a negative correlation between the thickness of transverse carpal ligament and the ratio of broken area. Conclusion: high frequency ultrasound can clearly display the echo of the wall of the carpal tunnel and the nerve and tendon of the carpal tunnel. By combining with quantitative measurement, the syndrome of carpal tunnel can be accurately diagnosed and the etiology can be determined. To provide effective help for clinical choice of treatment methods and timing.
