Re: can someone explain my MRI results please
Welcome to the board. I'm not quite sure what your previous surgery was, so take that into consideration as you read my comments!
First, it looks like you have reason to have lots of pain as several nerves are being impacted. Your other surgery must have been a discectomy as you still have discs at both the L4-L5 and L5-S1 levels.
[B]at L4/L5 the disc is dehydrated and a focal central disc protrusion is encroaching upon the anterior thecal sac and is touching both traversing L5nerve roots[/B]
When discs dry out, they tend to flatten. This disc is protruding beyond the disc space and is pushing into the thecal sac, which is the tough fibers that surround the central canal. This protrusion is also touching both of the L5 nerve roots. Both of these things can cause the type of nerve pain that radiates down the buttocks, legs and into the feet.
[B]at L5/S1 there are severe degenerative changes with irregular endplates,marginal osteophytes, modic ii endplate-related signal alterations, severe loss of disc height and facet joint hypertrophy; evidance of a left sided hemilamanectomy defect at L5/S1 with a small fibrotic scar left lateral of the thecal sac [/B]
At the L5-S1 level there are severe degenerative changes. These are showing as bony overgrowths and "bumpy" margins on the edges of the endplates.
End plates are the top bottom portions of the vertebral bodies that interface with the vertebral discs, and provide nourishment for the discs. When the disc herniates, it can cause end-plate abornalities and make it difficult to function properly. This can result in the disc not receiving enough nuitrition, and the disc dries out.
The report indicates there was a discectomy on the left side and there is now a small amount of scar tissue.
It would appear that the issue that is causing you problems is primarily at the L4-L5 disc where it is impacting the L5 nerve root. The surgeon will want to do what he can to lessen the impact on the L5 nerve root, first trying conservative treatments.
It is pretty standard treatment to not leave a nerve compressed for too long as there is a risk of permanent nerve damage.
