摘要
背景:以往研究证明多种内环境因素共同作用引发椎间盘退变,最重要的机制为椎间盘软骨终板的退变。目的:分析椎间盘退变与终板形态的关系。方法:回顾性分析62例因椎间盘源性慢性下腰痛和79例因髓核脱出致神经根性症状患者的腰椎MRI正中矢状位图像资料。根据腰椎MRI正中矢状位T1W1图像确定终板形态,T2W1图像确定椎间盘退变程度分级。结果与结论:平坦型和不规则型终板最常见于椎间盘退变人群下腰椎,L5/S1平坦型最多见。髓核脱出组与椎间盘源性慢性下腰痛组中凹陷型终板椎间盘退变程度均较平坦型、不规则型低,平坦型终板椎间盘退变程度较不规则型低(P<0.01)。两组间凹陷型与不规则型终板椎间盘退变程度差异无显著性意义,髓核脱出组平坦型椎间盘退变程度较椎间盘源性慢性下腰痛组高(P<0.05)。提示随着椎间盘退变程度的加重,软骨终板形态有由凹陷型向平坦型、不规则型依次转变的趋势。
