114例腰椎间盘退变伴终板骨软骨炎的MRI诊断分析

MRI findings in the diagnosis of the end-plate osteochondritis with lumbar disc degeneration in 114 patients

目的探讨腰椎间盘退变伴终板骨软骨炎的磁共振成像(MRI)表现及临床意义。方法回顾性分析经临床及影像学确诊114例腰椎间盘退变伴终板骨软骨炎的MRI表现。结果 114例病例中共累及终板234个,按Modic分型其中Ⅰ型82个(35%);Ⅱ型136个(58.1%);Ⅲ型16个(6.8%);单发累及72例(63.2%),多发累及42例(36.8%);病变好发于下腰段。结论腰椎间盘退变伴终板骨软骨炎是造成临床上腰痛的重要原因之一,MRI是该病的有效检查方法,能够反映该病的临床特点。

Objective To investigate MRI findings and chinical significance of lumbar disc degeneration with end-plate osteochondritis.Methods MRI features of 114 cases from end-plate osteochondritis in lumbar disc degeneration were retrospectively analyzed.Results 234 end-plate osteochondritis were diagnosed in 114 cases of lumbar disc degeneration.And they were classified into 3 types according to Modic classification,in which 82 cases（35%） were Modic type Ⅰ,136 cases（58.1%） were Modic type Ⅱ,and 16 cases（6.8%） were Modic type Ⅲ.There are 72 cases（63.2%） from single end-plate osteochondritis and 42 cases（36.8%） from multiple end-plate osteochondritis.The lesions were usually found in the lower lumbar spine.Conclusion End-plate osteochondritis was one of the main reasons causing low back pain.And MRI is the best way to detect the lesion and reflect its pathological foundation.
