Re: Help with MRI Results
My guess is that you may have some pain coming from the L5-S1 level, too. Your problems at this level are almost as severe as those at the L4-L5 but there is less stenosis. I guess the doctor felt it was less severe or perhaps that this level was not causing nerve compression, so for that reason, he did not elect to operate on it too.
But in hindsight, I suspect he will wish he had done both levels during your first surgery.
At L4-L5 there are changes in the facet joint which are of the arthritic type. The joint is enlarging and the ligament flavum is thickening up. At this level there is a mild disc bulge and an annular tear in the outer rim of the disc which is pushing out of the disc space and encroaching into the foraminal opening on the right side. The foramina is an opening through which the spinal nerve passes out from the spine to other parts of the body.
At L5-S1 the disc is drying out and there is a disc bulge that is pushing out to the posterior side. This disc also has a small annular tear. However, unlike at L4-L5, the disc problem is not causing any stenosis and therefore, there is no nerve compression going on at this level.
The left facet joint at this level is showing some small signs of arthritis.
