CT Diagnosis and Classification of Lumbar Spine Degenerative Disease:1180 Cases / 实用放射学杂志

ABSTRACT

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 typesintervertebral 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.
