Second Microdisctomy
i guess you are asking which op to go for? which segment is it? I can only talk about lower lumbar segments. I think it depends on the amount of disc left and your age. if you are older and less active, or the disc is very dehydrated and has lost a lot of height, then it might be best to skip to fusion. if you are younger and more active, especially if you still have a good amount of the disc left (significantly more than 50%] then it much less invasive to try another microdiscectomy. Fusion is completely irreversible and has a much higher risk of side effects.
