摘要
目的探讨腰椎间盘退变中椎体终板骨软骨炎的磁共振成像(MRI)表现及其临床意义。方法搜集2008年3月～2009年3月间经临床及影像学诊断的腰椎椎体终板骨软骨炎115例,累及235处腰椎终板,全部病例均有不同程度的临床症状。回顾性分析终板及邻近椎体骨质信号改变。结果 115例椎体终板骨软骨炎患者中,有235处终板信号异常,按Modic分型,其中Ⅰ型改变有91处(占38.7%);Ⅱ型改变有120处(占51.1%),Ⅲ型改变有24处(占10.2%)。伴随改变:合并椎间盘膨出23处,突出97处,脱出6处,Schmorls结节68处,椎体滑脱7处,压缩性骨折4处。结论终板骨软骨炎是造成临床局部疼痛的原因之一,低场MR I能清楚显示腰椎间盘退变中椎体终板炎各期的信号特点,对病灶的显示满意,是检查本病的最佳方法。
Aim To explore the magnetic resonance imaging（MRI）performance and clinical significance of vertebral end-plate osteochondritis in lumbar disc degeneration.Methods 115 cases of vertebral end-plate osteochondritis were collected by the clinical and imaging diagnosis from Mar.2008 to Mar.2009,involving 235 lumbar end-plates.All patients had various degrees of clinical symptoms.The signal change of vertebral end-plate and adjacent bones was analyzed.Results In 115 cases of vertebral end-plate osteochondritis,there were 235 end-plates signal abnormalities.According to Modic categorization,there were 91 cases（38.7%）of Modic type Ⅰ,120 cases（51.1%）Modic type Ⅱand 24 cases（10.2%）Modic type Ⅲ.Accompanied changes were merge disc bulges 23 cases,disc herniations 97 cases,disc extrusions 6 cases,Schmorls nodules 68 cases,vertebral spondylolisthesis 7 cases,and compression fractures 4 cases.Conclusion The end-plate osteochondritis is one of the reasons to cause the clinical local pain.Low field MRI can clearly showed the signal characteristics of end-plate osteochondritis phases in lumbar disc degeneration,and satisfaction for the lesions,which is the best way to check the disease.
