Abstract:
Objective To study the relationship between degenerative lumbar spondylolisthesis and degeneration of cartilage endplate by magnetic resonance imaging.Methods The median sagittal scanning of LA/L5 and L5/S1 intervertebral discs of all subjects were performed by magnetic resonance imaging with T2.Measureed the inclination angle of the front half of the endplate and the inclination angle of the posterior half of the endplate,then the ratio of the anterior horn and the posterior horn was calculated as the change rate of the endplate.The differences of the rate of cartilage endplate in the corresponding stage of spondylolisthesis group and normal group were compared.Results In L4 lumbar spondylolisthesis group,both upper and lower endplate of L4/L5 intervertebral disc have significant differences between the lumbar spondylolisthesis group and the normal group (t =11.280,-3.765,P =0.000).In L5 lumbar spondylolisthesis group,there are significant differences between the lumbar spondylolisthesis group and the normal group (t =11.280,-3.765,P =0.000),both upper and lower endplate of L5/S1 intervertebral disc;and significant differences were found among the upper and lower endplates of the L5/S1 (t =4.633,P =0.000).Among all the subjects,between the upper and lower endplate of L4/L5,significant differences were found,too(t =17.377,3.137,2.199,P =0.000,0.005,0.035).In addition to the above,the differences were not statistically significant.Therefore,lumbar spondylolisthesis can lead to degenerative in cartilage endplate of Slippage stage.Conclusion The degree of degeneration of the anterior and the posterior half of the same cartilage endplate is asymmetrical,for example,the degeneration of the posterior half of the upper endplate is worse than that of the anterior half of the plate,but the degeneration of the anterior half of the lower endplate is worse than that of the posterior half endplate.The degenerative degree of cartilage endplate was less affected by lumbar spondylolisthesis in the non slip stage.
