A lot of the spinal surgeons I have seen want to perform a fusion. ADR is ruled out because of the degeneration in my facets that might be able to handle the load. Also, I don't feel comfortable with ADR since the technology is not new and the fact that I still have radicular pain after my lumbar microD. I am just torn because most of the surgeons are saying I would do fine with either a minimally invasive PLIF, TLIF, or just doing a ALIF. I was just wondering what would be the pros and cons of each technique? Also, is it true that if the fusion is done from the back and if the cage and screws are properly placed that adjacent segmental levels might not be effected? Also, i heard ALIF stops the adjacent levels from being affected the least because the paraspinal muscles are not being cut which are crucial for healing and stability. Please let me know. My biggest worry with fusion is the possibility of having another surgery down the line because of the adjacent levels being effected. I want to know which method might stop or be the slowest progression.
