摘　　要：目的　探讨脊柱椎间盘退变中终板骨软骨炎的MRI表现及其临床意义。资料与方法　搜集 1997年 9月～ 1999年 5月椎间盘退变的MRI资料 ,腰椎 6 73例 ,其中男 4 0 5例 ,女 2 6 8例 ,年龄 13～ 83岁 ,平均 4 7岁 ;颈椎 6 6 2例 ,其中男 4 16例 ,女 2 4 6例 ,年龄 2 2～ 86岁 ,平均 5 1岁。全部病例均有不同程度的临床症状。分析终板及邻近椎体骨质信号改变。结果　 6 73例腰椎间盘退变中 ,192例有终板骨软骨炎 ,占 2 8.5 % ,共累及 32 6个终板 ;135例有Schmorl结节病灶 ,其中 4 0例在结节及周围骨质中存在终板骨软骨炎类似改变。 6 6 2例颈椎间盘退变中 ,139例有终板骨软骨炎 ,占 2 1.0 % ,共累及 2 75个终板 ;2 9例Schmorl结节中 16例在结节及周围骨质中存在终板骨软骨炎样改变。按照不同的MRI表现 ,将终板骨软骨炎分为 4型。结论　终板骨软骨炎是造成临床局部疼痛的原因之一 ,MRI是检查本病的最佳方法。临床工作中注意终板骨软骨炎的存在及其临床意义 ,将为颈。Objective To discuss MRI findings and clinical significance of end plate osteochondritis in disc degeneration.Materials and Methods During the period of Sep. 1997～May 1999, MRI was performed in 673 cases with lumbar disc degeneration and in 662 cases with cervical 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 673 cases with lumbar disc degeneration, end plate osteochondritis was identified in 192 (28.5%), involving 326 end plates, and Schmorl's nodule was seen in 135, of which 40 showed changes similar to end plate osteochondritis in the nodules and adjacent bones. Of 662 cases with cervical disc degeneration, end plate osteochondritis was present in 139 (21.0%), affecting 275 endp lates, and Schmorl's nodule was demonstrated in 29, of which 16 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.
