【摘要】：目的通過對(duì)頸椎矢狀位參數(shù)的MRI測(cè)量,分析不同矢狀位曲度狀態(tài)下的脊髓型頸椎病患者各主要頸椎矢狀位參數(shù)之間的相關(guān)性,從而找出具有代表意義的頸椎矢狀位參數(shù)。方法回顧性分析2015年7月—2016年1月因脊髓型頸椎病就診的88例患者資料,于頸椎矢狀位MRI T_2加權(quán)像上測(cè)量C_2~C_7 Cobb角、T_1傾斜角(T_1 slope,T_1S)及C_2~C_7矢狀位軸向距離(C_2~C_7 sagittal vertical axis,C_2~C_7 SVA)。根據(jù)C_2~C_7 Cobb角大小不同將患者分為前凸組(Cobb角≥10°,48例)及變直組(Cobb角0~10°,40例)。數(shù)據(jù)測(cè)量可靠性采用組內(nèi)相關(guān)系數(shù)(intraclass correlation coefficient,ICC)表示,各影像學(xué)參數(shù)的相關(guān)性檢驗(yàn)采用Pearson相關(guān)進(jìn)行分析。結(jié)果頸椎各參數(shù)的ICC為0.858~0.946,組內(nèi)測(cè)量一致性良好。變直組C_2~C_7 Cobb角為(5.6±2.4)°,T_1S為(22.2±6.7)°,C_2~C_7 SVA為(10.2±5.4)mm;前凸組C_2~C_7 Cobb角為(20.1±8.2)°,T_1S為(23.4±8.9)°,C_2~C_7 SVA為(8.2±4.6)mm。變直組3個(gè)參數(shù)間均無相關(guān)性,其中T_1S與C_2~C_7 Cobb角(r=0.100,P=0.510);T_1S與C_2~C_7SVA(r= 0.100,P=0.500);C_2~C_7 Cobb角與C_2~C_7 SVA(r=0.080,P=0.610)。前凸組T_1S與C_2~C_7 Cobb角之間成正相關(guān)(r=0.540,P=0.000),T_1S與C_2~C_7 SVA之間成負(fù)相關(guān)(r= 0.450,P=0.001),C_2~C_7 Cobb角與C_2~C_7SVA之間無相關(guān)性(r= 0.003,P=0.980)。結(jié)論具有頸椎生理前凸的脊髓型頸椎病患者,可僅以MRI測(cè)量的T_1S值作為評(píng)判矢狀位曲度的主要參數(shù)代表;而對(duì)于頸椎生理前凸變直患者,需要T_1S、C_2~C_7 Cobb角、C_2~C_7 SVA進(jìn)行測(cè)量來綜合評(píng)判。
[Abstract]:Objective to analyze the correlation between the main cervical spine sagittal position parameters in patients with cervical Spondylotic myelopathy (CSM) under different sagittal curvature by measuring the sagittal position parameters of the cervical vertebrae by MRI. Methods the data of 88 patients with cervical Spondylotic myelopathy from July 2015 to January 2016 were retrospectively analyzed. On the sagittal MRI T2-weighted images of cervical vertebrae, the C_2~C_7 Cobb angle T _ S _ 1 sloping angle T _ 1S) and C_2~C_7 sagittal axis distance were measured. According to the size of C_2~C_7 Cobb angle, the patients were divided into four groups: the Cobb angle 鈮，
