【摘要】：目的:研究應(yīng)用高頻超聲對腕橫韌帶厚度、腕管斷面積與腕管內(nèi)容物斷面積之比進(jìn)行定量測量,分析診斷閾值、敏感度、特異度,為超聲診斷腕管綜合征增加敏感性、特異性。方法:選取2010年10月-2013年5月門診患者組(CTS)26例35側(cè),經(jīng)電生理及臨床癥狀確診,對照組健康志愿者30例60側(cè),年齡性別與患者組匹配。高頻超聲測量豌豆骨水平及鉤骨鉤水平腕橫韌帶厚度、腕管斷面積與腕管內(nèi)容物斷面積之比,所有計(jì)量資料以“均數(shù)±標(biāo)準(zhǔn)差”表示,采用兩樣本均數(shù)的t檢驗(yàn),P0.05有統(tǒng)計(jì)學(xué)意義。根據(jù)所得測量指標(biāo)采用spss13.0軟件繪制ROC曲線,測定各測量指標(biāo)的診斷閾值,計(jì)算敏感度與特異度。并比較腕橫韌帶厚度與斷面積比值之間的相關(guān)性。結(jié)果:豌豆骨水平腕橫韌帶厚度最佳截點(diǎn)值取0.295cm時(shí),靈敏度為74.3%,特異度為86.7%。豌豆骨水平腕管斷面積與腕管內(nèi)容物斷面積比值取最佳截點(diǎn)值2.44時(shí),靈敏度為61.7%,特異度為77.1%。鉤骨鉤水平腕管斷面積與腕管內(nèi)容物斷面積比值取最佳截點(diǎn)值2.447,靈敏度為83.3%,特異度為62.9%。腕橫韌帶厚度與斷面積比值呈負(fù)相關(guān)性。結(jié)論:高頻超聲可以清晰顯示腕管壁及腕管內(nèi)神經(jīng)、肌腱等結(jié)構(gòu)回聲,通過結(jié)合定量指標(biāo)測量,可準(zhǔn)確診斷腕管綜合征,并可明確病因情況,為臨床選擇治療方式及時(shí)機(jī)提供有效幫助。
[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 鹵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.
