I recently had an Mri in which it came back that I have an Broad-based disc bulge with facet joint arthropathy and ligamentum flavum hypertrophy without significant spinal canal narrowing or nueroforaminal narrowing in the L4-L5 . Also, a Broad- based disc bulge without significant final canal narrowing or nueroforaminal narrowing in the L5- S1. What does this means?
