摘要
目的:提高对腰椎小关节退变性损害的全面认识。方法:对60例腰椎小关节行CT扫描,采用骨窗和软组织窗进行观察分析。结果:在60例病例中,腰椎小关节突退变,增生硬化14例、关节突肥大6例、骨质疏松21例、骨赘形成18例、半脱位(对位不良)9例、皮质下囊变9例;小关节间隙退变,间隙变窄20例、不均17例、消失8例、真空征19例、关节腔内游离体6例;骨性关节面退变性改变,关节面不平53例、硬化34例,关节囊钙化5例,黄韧带肥厚4例、钙化5例。结论:CT扫描能准确观察到腰椎小关节退变性损害的改变,能为临床治疗提供较可靠的影像依据。
Objective：To improve cognition of degenerative lesion in lumbar zygapophysis. Materials and methods：To analysis the CT images of the 60 cases with bone window and soft tissue window. Results：in 60 cases,CT findings of degenerative lesion in lumbar zygapophysis were founded proliferation hardening in 14 cases,hypertrophy in 6 cases,bone rarefaction in 21 cases,osteophyma in 18 cases,subluxaion in 9 cases;it was founded cataplasis in joint space with narrowing in 20 cases,unevenness in 17 cases,underpressure in 19 cases,corpus liberum in articular cavity in 6 cases;it was founded changes in articular facet with uneven in 53 cases,hardening in 34 cases,calcification in articular capsule in 5 cases,calcification with arcuate ligaments in 5 cases,and thickening in 4 cases. Conclusion：Thin slice CT scanning can accurately diagnose the degenerative lesion in lumbar zygapophysis and provid reliable images for treatmeat.
