A 29-year-old female asked:

If i had a fusion of l4-s1 with a spacer at l4/5, why would my most recent mri say that there is disc-desiccation and at l5/s1 also a disc protrusion?

Adjacent degeneratio: Because of the fusion there is more stress on the docs above and below leading to their degeneration like narrowing, bulging or herniation.However some people can get degenerative discs adjacent to another abnormal disc just spontaneously.

It's possible that L5-S1 is not fused and therefore there is still some stress on the disc. Even if it is fused studies ahi that without a spacer or internist fusion there is still some motion anteriotly(front) in the disc space
