The Association Of Schmorl’s Nodes With Lumbar Degeneration And Lowback Pain

Objective:To discuss the incidence, Schmorl’s nodes on MRI,and analyze the relationship with lumbar degeneration and lowback pain. Methods:The lumbar spine on MRI of218patients were analyzed.The sex and the numbers of schmorl’s nodes were investigated.The size,place occured in different vertebra,the signal of the vertebra disc,the vertebral osteophyte,the vertebral endplate contour were contrast analyzed.Results:182Schmorl’s nodes were detected in218participants (male:99, female:119) patients SchmorPs nodes were found in82cases (male:45, female:37).Most nodes in the middle and behind one third of vertebral endplate.The signal of the bone marrow surrounding the Schmorl’s nodes with Modic Ⅰ type were the most common. Straight endplate and Schmorl’s node were obviously relevant(P<0.05),Schmorl’s node associated with anterior vertebral osteophyte(P<0.05),Normal intervertebral disc and the disc associated with Schmorl’s node scores have significant difference in degeneration(P<0.05).Conclusion:The incidence of lumbar Schmorl’s node of the male were more than the female’s.Most Schmorl’s nodes located at the edge of L2and L3.With Schmorl’s node adjacent intervertebral disc were related to bulging disc and disc herniation.The Schmorl’s nodes had obvious relationship with the shape of endplate and the osteophyte.Interestingly, Schmorl’s nodes were highly associated with of disc degeneration.
