Mark, here is what my MRI indicates (I could use some help understanding it as well):
Discogenic disease, spondylosis, and a diffuse posterior disc bulge at L5/S1. Moderate to severe degree of endplate osteitis secondary to chronic discovertebral trauma. Postsurgical changes are indentified as L5/S1. No epidural fibrosis, no residual or recurrent HNP. Remaining disc spaces of the lumbosacral spine are otherwise unremarkable.
