Relationship between intervertebralis disc height and pfirrmann’s degenerative degree:

Abstract

This study aims to determine the relationship between disc height as objective data and the degree of disc degenerative Pfirrmann score assessed on MRI imaging, the imaging modality with the best current degenerative lumbal disease’s diagnosis. The measurements of disc height and Pfirrmann degenerative degree of the intervertebral disc were performed on a T2WI MRI sequence, sagittal sections of the 1-2 lumbar intervertebral discs to 5-sacral 1 (5 disc levels) using dicom MRI data using the Horos dicom viewer software. Analysis of the correlation between disc height and the degree of degeneration on MRI was performed using the Pearson correlation test. Statistical tests were performed using SPSS software (SPSS Inc., Chicago, IL, USA). The results were evaluated with a significance value of p<0.005. The results of the Pearson test in the three groups of patients, namely in the HNP L4-L5, HNP L5-S1 and HNP patient groups at both disc levels showed an inverse relationship between disc height and Pfirrmann's degenerative degree which was statistically significant, with values ​​in the L4 HNP group.
