I am new to this so I am not sure if I am putting the info in the correct areas but, I need to understand what is wrong with my father Here is how it reads:

L4-L5: Broad-Based discoosteophyte bulging seen, marked narrowing of bilateral recess seen, moderate to marked central spinal canal stenosis seen
Disc degenerative changes with spinal canal stenosis greater at L4-L5 level as described above.


does anyone understand this and could you please try to explain it?

and thank you.
