腰椎椎体后缘骨质异常致腰椎管狭窄症的CT诊断

CT Diagnosis of Lumbar Spinal Canal Stenosis Caused by Lumbar Posterior Marginal Osseous Abnormalities

目的:探讨腰椎椎体后缘骨质异常致椎管狭窄的病因、CT表现及诊断价值。方法:回顾性分析腰椎椎体后缘骨质异常致椎管狭窄150例的临床表现及CT所见。结果:椎体后缘软骨结节(67例,占44.67%);椎间盘钙化(45例,占30%);椎体后缘骨质增生(29例,占19.33%);后纵韧带骨化(9例,占6%)。结论:CT扫描能明确诊断腰椎椎体后缘骨质异常所致的腰椎管狭窄症,为临床诊断和治疗腰腿痛提供可靠的影像学依据。

Objective TO investigate the pathogenesis pathology, CT findings and their diagnostic value of lumbar spinal canal stenosis caused by lumbar posterior marginal osseous abnormality. Methods The clinical representation and CT view of 153 cases with lumbar spinal canal stenosis caused by lumbar posterior marginal osseous abnormality were retrospectively analysed. Results The pathogenesis pathology of lumbar spinal canal stenosis ： Lumbar posterior marginal cartilage node （67 cases,44. 67% ） ;Intervertebral disc calcification （45 cases, 30% ） ; Lumbar posterior marginal osteophytic formation （29 cases, 19. 33% ） ;Post longitudinal ligaments calcification（9 cases ,6% ）. Conclusion CT scans can provide reliable evidence for diagnosis of lumbar spinal canal stenosis caused by lumbar posterior marginal osseous abnormality, and provide reliable images for diagnosis and treatment of the patients with pain in the low back and leg.
