青少年单纯性椎小关节紊乱的影像学诊断

Imaging diagnosis of juvenile simple disorder of vertebrae

目的探讨青少年脊椎椎小关节紊乱的发病机制，分析其临床表现及影像学表现，以明确诊断。方法回顾性分析250例10～30岁年龄组椎小关节紊乱引起颈、胸、腰背部酸痛患者的脊椎X线平片或CT平扫片或MRI片资料。结果青少年椎小关节紊乱有典型椎小关节不对称、关节面笔样增生硬化及周围软组织非特异炎性改变等影像学表现。结论青少年单纯性椎小关节紊乱在影像学上可以明确诊断及鉴别诊断，X线检查仍是诊断椎小关节紊乱的重要手段，CT及MRI可以更清楚显示椎小关节及其周围软组织的改变，还可以鉴别椎间盘突出性改变或其他原因引起的病患。

Objective To explore the pathogenesis of juvenile disorders of spine facet joints and to clarify the diagnosis by concluding the clinical and imaging manifestations. Methods Retrospectively analyzed imaging data of 250 patients from 10--30 years with disorders of spine facet joints including X-ray and CT and MR1. Results Reasons of juvenile disorders of spine facet joints has unique imaging manifestations of asymmetric of small joints and joint surface hyperplasia like pen, of nonspecial inflammation in surrounding soft tissue. Conclusions Imaging can diagnose and differentiate diagnosis juvenile disorder of spine facet joints. X-ray is also the primary method. Not only CT or MRI image can more clearly display the changes of spine facet joints and surrounding soft tissue,but also differentiate diagnosis disc herniation and other diseases.
