摘要
回顾性分析2015年1月至2017年9月河南省洛阳正骨医院87例颈椎手术患者的MRI影像资料，以椎体后缘后纵韧带线样低信号影连续性中断或显示不清或其在T2加权像上局部出现高亮信号诊断为后纵韧带破裂，并与术中探查结果比较，分析MRI对颈后纵韧带破裂诊断的准确性。87例中MRI诊断为破裂者31例，术中见破裂者38例（30例为MRI诊断，8例MRI未诊断），MRI与手术探查的诊断比较差异无统计学意义（χ2=1．17，P=0．28）。MRI对后纵韧带破裂的诊断准确率、敏感性和特异性分别是0．90、0．79和0．98。提示MRI对颈后纵韧带破裂具有良好的诊断作用，可为手术方式的选择提供参考。
Magnetic resonance imaging （MRI） data of 87 patients with suspected cervical posterior longitudinal ligament （PLL） rupture, who underwent cervical spine surgery in Luoyang Orthopedic Hospital from January 2015 to September 2017, were analyzed retrospectively. The criteria of MRI diagnosis for PLL rupture were the low signal image of the PLL on the posterior margin of the vertebral body, the discontinuity or continuous interruption, or the local highlighting signal on the T2 weighted image. According to intraoperative findings, the diagnostic accuracy of MRI for PLL rupture was examined, Among 87 patients,31 cases were diganosed as PLL rupture by preoperative MRI; and 38 cases were confirmed by intraoperative exploration, of whom 30 were diagnosed with MRI, and 8 were missed by MRI. The accuracy, sensitivity and specificity of MRI in the diagnosis of ruptured PLL were 0.90, 0.79 and 0.98 respectively. MRI has a good diagnostic efficiency in PLL rupture, which can be used for preoperative investigation.
