腰椎退变中终板骨软骨炎的MRI表现

MRI Findings of the lumbar end-plate osteochondritis

目的:探讨腰椎退变中终板骨软骨炎的MRI表现及其临床意义。材料与方法:搜集2012年1月至7月之间腰椎退变的MRI资料共954例,其中男491例,女463例,年龄14-88岁,平均51岁;并分析终板及邻近椎体骨质信号改变。结果:954例腰椎间盘退变中,217例有终板骨软骨炎,占22.7%,共累及329个终板;192例有Schmorl结节病灶,其中57例在结节及周围骨质中存在终板骨软骨炎改变。按照MRI不同的表现,将终板骨软骨炎分为4型。结论:MRI是检查本病的最佳方法,终板骨软骨炎是造成临床局部疼痛的原因之一,临床工作中需注意终板骨软骨炎的存在及其临床意义。

Purpose：To discuss MRI findings and clinical siginificance of end-plate osteochondritis in the lumbar.Materials and Methods：During the period of January^July 2012,MRI was performed in 954 cases with lumbar disc degeneration.MRI findings were retrospectively reviewed,and the signal intensity of the end-plate and its adjacent vertebral bones was measured and analyzed.Results：Of 954 cases with lumbar disc degeneration,end-plate osteochondritis was identified in 217（22.7%）,involving 329 end-plate,and Schmorl′s nodule was seen in 192,of which 57 showed changes similar to end-plate osteochondritis in the nodules and adjacent bones.Based on lesion′s signal intensity on MRI,end-plate osteochondritis was classified into 4 types.Conclusion：Clinically,end-plate osteochondritis is one of the reasons causing local pain.MRI is the best modality to detect the lesion.In clinical practice,being aware of the possibility of end-plate osteochondritis is helpful for its diagnosis and management.
