Abstract:
Objective:To analyzed the relationship between lumbar endplate Modic area changes rate and low back pain by measuring MRI T2 sagittal image of lumbar endplate Modic area changes rate. Methods:From December 2011 to June 2012,70 patients with low back pain in operation were evaluated on pain by VAS and function by JOA ,and examined by MRI including 39 males and 31 females with an average age of (51.00±11.89) years ranging from 29 to 72 years old. Among them, 54 cases had lumbar endplate Modic changes involving 15 cases in types ModicⅠ,21 cases in type ModicⅡ,11 cases in type ModicⅢ,mixed type Modic in 7 cases (eliminated for too few cases). Modic area changes and corresponding vertebral area were measured on MRI T2 median sagittal. The areas of two ways were compared to yield the rate of changes for Modic ,for multisegmental Modic changes to calculate the total ratios. A correlation was observed among JOA ,VAS and the rate of Modic changes. Results:The correlation coefficient of change rate of ModicⅠwith JOA score was r=-0.308,P=0.048<0.05,there was a negative correlation;the correlation coefficient of change rate of ModicⅠwith VAS scores was r=0.428,P=0.021<0.05,there was a positive correlation. The correlation coefficient of change rate of Modic Ⅱwith JOA score was r=-0.375,P=0.043<0.05, there was a negative correlation;the correlation coefficient of change rate of Modic Ⅱwith VAS score was r=0.352,P=0.041<0.05, there was a positive correlation. The area change rate of Modic Ⅲhad no significant correlation with low back pain de-gree (P>0.05). Conclusion:ModicⅠandⅡarea changes rate of of patients with low back pain is closely related to the degree of pain low back pain,ModicⅢarea changes rate is not significant correlated to the degree of lower back pain.
