C5/C6颈椎间盘突出症患者颈髓受压程度与颈椎MRI测量值相关性分析

目的探讨C5/C6颈椎间盘突出症患者颈髓受压比例(E值)与颈椎磁共振成像测量值间相关性。方法回顾性分析2017年4月至2019年4月我院放射科接诊的80例C5/C6颈椎间盘突出症患者,入院后均行MRI检查,根据颈椎MRI矢状位成像上按照E值分为1组(E值≥66%,n=24)、2组(E值33%~66%,n=29)、3组(E值<33%,n=27)。对比3组一般资料性别、年龄、病程及颈椎功能(JOA评分)]及椎间孔面积(M值)、椎间隙前缘高度(D值)、颈椎C2~7Cobb角等MRI其他相关测量值,分析E值与M值、D值、颈椎C2~7 Cobb角间关联性。结果经单因素方差分析可知,3组JOA评分存在明显差异(P<0.05),且两两比较,1组高于2组,2组高于3组(P<0.05);3组E值、M值、D值及C2~7 Cobb角存在明显差异(P<0.05),且两两比较,1组高于2组,2组高于3组(P<0.05);经Spearman分析可知,E值与M值、D值及C2~7 Cobb角呈明显正相关(r1=0.621,P1=0.002;r2=0.604,P2=0.003;r3=0.579,P3=0.011)。结论E值越低,C5/C6颈椎间盘突出症患者脊髓受压越严重,颈椎功能越差,患者颈椎M值、D值、颈椎C2~7 Cobb角与E值均存在明显正相关关系,通过MRI测定患者颈椎M值、D值及颈椎C2~7 Cobb角,可对患者颈髓受压严重程度进行评估,具有较高应用价值。

Correlation Analysis between Different Spinal Cord Compression Ratios and Cervical MRI Related Measurements in Patients with C5/C6 Cervical Disc Herniation

Objective To investigate the correlation between the ratio of cervical spinal cord compression(E value)and cervical magnetic resonance imaging in patients with C5/C6 cervical disc herniation.Methods A retrospective analysis of 80 patients with C5/C6 cervical disc herniation from April 2017 to April 2019 in our hospital radiology department was performed.All patients underwent MRI after admission.Acco rding to the cervical vertebra MRI sagittal imaging,acco rding to the E value.There were 1 group(E value≥66%,n=24),2 groups(E value 33%to 66%,n=29),and 3 groups(E value<33%,n=27).Compa re3 groups of general datasex,age,disease course and cervical vertebra function(JOA score)]and intervertebral foramen(M value),intervertebral space leading edge height(D value),cervical C2~7 Cobb angle and other related MRI measurements Value,analysis of E value and M value,D value,cervical C2~7 Cobb angle correlation.Results One-way analysis of variance showed that there were significant differences in the JOA scores of the three groups(P<0.05),and group 1 was higher than group 2,and group 2 was higher than group 3(P<0.05).M value,D value and C2~7 Cobb angle were significantly different(P<0.05),and compared with the two groups,group 1 was higher than group2,group 2 was higher than group 3(P<0.05).Spearman analysis showed that E The values,were positively correlated with M value,D value and C2~7 Cobb angle(r1=0.621,P1=0.002;r2=0.604,P2=0.003;r3=0.579,P3=0.011).Conclusion The lower the E value,the more severe the spinal cord compression in patients with C5/C6 ce rvical disc herniation.The wo rse the cervical vertebrae function,the positive correlation between the M value and D value of the cervical vertebrae and the C2~7 Cobb angle of the cervical vertebrae and the E value.MRI measurement of cervical M value,D value,and cervical C2~7 Cobb angle can assess cervical spinal cord compression,severity and has a high application value.
