It depends on the entire picture of your spine. It is possible that you may be a candidate but all your diagnostic studies would have to be reviewed. I have not allowed surgery because I had a anterior fusion at the C-6,7 with cadaver and plate. I am worried about my lower back because of my upper body weight. Obviously you need to try all conservative modalities, including active strengthening and stabilization exercises, the use of anti-inflammatories, chiropractic, injections.
Weight loss is a consideration.
If you meet the weight limit criterion, you may be a candidate for this procedure. There are many experimental studies being done at this time. Some include drugs that help the nerves regenerate, such as the use of robotics, and electrical implants to stimulate extremity motions. This sounds like it would make the spine stiff. It is true a fusion will make the spine stiff because the purpose of a fusion is to eliminate motion over a painful segment that includes two vertebrae, the intervening disc and the connecting joints.
