腰椎退行性病变CT分型(附1180例分析)

目的综合分析腰椎退行性病变的CT表现。方法分析1180例退变性腰腿痛患者的腰椎CT表现,按腰椎相关结构对其表现分类,结合临床表现,对腰椎退变的影像表现进行分型诊断。结果腰椎退变存在6种类型,即:椎间盘退变型,退变率65.3%;骨质退变型,退变率48.1%;椎小关节退变型,退变率36.0%;韧带退变型,退变率25.4%;退变性腰椎管狭窄,退变率44.0%;退变性腰椎失稳,退变率25%。前4种为原发性腰椎退变型,后2种为继发性腰椎退变型。结论腰椎退行性病变的CT分型有利于临床治疗。

CT Diagnosis and Classification of Lumbar Spine Degenerative Disease: 1180 Cases

Objective To analyse CT signs of lumbar spinal degenerative diseases.Methods CT findings of lumbar spine in 1180 cases with degenerative disease lumbocrural pain were analysed.CT classification of degenerative disease of lumbar spine was carried out according to the lumbar structures in combination with clinical sign.Results Lumbar spinal degenerative disease could be classified into 6 types:intervertebral disc degeneration(degenerative rate 65.3%);lumbar vertebra degeneration(degenerative rate 48.1%);vertebra facet joint degeneration(degenerative rate 36.0%);ligment degeneration(degenerative rate 25.4%) ;degenerative stenosis of lumbar spinal canal(degenerative rate 44.0%);and degenerative lumbar spine unstability(degenerative rate 25.0%).The former 4 types were belonged to primary degeneration of lumbar spine,the latter 2 types were belonged to secondary degeneration of lumbar spine.Conclusion CT classification of lumbar spinal degenerative disease is helpful to clinic in diagnosis and therapy.
