Abstract:
Objective To determine the correlation between the Modic degeneration of lumbar endplate on MRI and the pain provocation or degeneration of lumbar intervertebral discs observed on CT discography. Methods One hundred and twenty lumbar intervertebral discs (40 L3-4, 40 L4-5, 40 L5S1 intervertebral discs) of 40 patients among 45 patients were examined. 120 intervertebral discs underwent discography guided by CT scan, according to Dallas Discography Description system, degeneration of lumbar intervertebral disc were divided into 0-3 grade, and pain provocation were graded into negative, indifferent and positive. On the basis of Modic classification system of the lumbar endplate changes and Pearce classification system of the degeneration of lumbar intervertebral disc, the lumbar endplate changes were divided into 0-3 grade, the degeneration of lumbar intervertebral disc were graded into Ⅰ-Ⅴ. All the results were analysed by Chi-Square test for the correlations. Results There was positive correlation between pain provocation test and the lumbar endplate Modic degeneration; There was a positive correlation between the Modic degeneration of lumbar endplate and the degeneration of lumbar intervertebral disc and so is the relation between the CT discography and MRI on discs. Conclusion There is positive correlation between pain provocation test and the Modic degeneration of lumbar endplate, it suggest the endplate might be one of the sources of low back pain. There is a positive correlation between the Modic degeneration of lumbar endplate and the degeneration of lumbar intervertebral disc.
