@readinglamb Yes, I have had at least three phone calls with their consultants. However, they do not determine the cost of the surgery. All they can do is connect potential patients to doctors in their area. I had an appointment this week with a neurosurgeon in my area who actually does the TOPs procedure. I thought I was a candidate with a level 1 spondololisthesis at L4/5 and stenosis. He said I would not be a candidate due to an "area of concern" at L3/4, even though it isn't severe. He thinks if it isn't addressed, it will cause problems down the line and a future surgery. If your DXA scan is -2.0 or greater, they will not do the surgery, according to this doctor. He says the screws will not hold with poor bone density.
