What Does Moderate Spondylytic Changes With No Radicular Compression Mean?

The alignment of the lumbar vertebrae is slightly distorted with       grade 1 retrolisthesis of L3 on L4. There are endplate degenerative changes       at L2 and L3. The conus medullaris is at L1. The disc heights are relatively       preserved with decrease in disc signal throughout. On axial imaging: At L1-2, a normal appearance is noted. At L2-3, mild degenerative changes are present with wide patency of the canal and foramina. At L3-4, again mild degeneration is present with no significant affect on the canal or foramina. At L4-5, a global disc bulge is present with bilateral extension and associated facet and ligamenta flava hypertrophy. There are possibly inflammatory changes in the facet joints at this level. The spinal canal is moderately reduced and there is some moderate reduction of both foramina. At L5-S1, there is a global disc bulge with associated facet hypertrophy resulting in mild spinal canal and bilateral foraminal narrowing. IMPRESSION: Overall moderate spondylitic changes. No frank evidence of radicular compression. YYYY@YYYY
