DO YOU MAKE A MINOR INCISION TO WORK ON THE SPINE AND DISC'S? IS THERE SCRAPING USUALLY INVOLVED? DO YOU ADD MATERIAL TO THE DISC CARTILAGE TO MAKE UP ITS SHRINKAGE, AND TO CREATE SPACE BETWEEN DISC'S?

MINIMALY INVASIVE SURGERY...There are multiple procedures available but in my case they made a small incision in my back and inserted a pipe that was used to allow easy tool access without further wear and tear to the incision. The vertebrae was drilled into to access the disc area. The hole also assists with providing space for the disc as they work to remove the disc material that impacts the spine. Procedures take about 2 hours each and you may require additional procedures on another or other disc(s).

you need to call them and contact their CS department in order to get the correct answers
