Re: any advice ?
Welcome to the board. First I have a couple questions before I can respond to your questions.
Were you making progress in your recovery and now you feel you are doing worse? What are your symptoms? Are you better than prior to surgery?
Have you had a consultation with your surgeon recently or had a new x-ray to see if you are fused? Sometimes a person will appear to be fused on an x-ray and it will turn out not to be the case, but usually x-rays are fairly good at showing bone growth.
The statistics you site are somewhat misleading. Of the people who do not have a successful outcome, only some of them have a non-fusion. In other cases, the surgery does not resolve their pain, or there is something else going on that the surgery didn't address. I'm not sure what percentage do not grow sufficient bone to make the fusion.
