Sandra McM: Herr Dr. Bertagnoli placed 2 artificial discs in my neck and one between L5 and my sacrum in 2005. It was very successful. I have scoliosis and had my back fused from L 4 to T2. In 1992. As a result, the disks around the fusions started to wear out. Until L4 was worn down to a triangular shape and rubbing directly on L5. He fixed it and put in the artificial disc. To retain movement. Now I think I have a broken fusion somewhere and I have additional discs wearing out in my neck. I have to find a way back to him to retain movement in my back and neck. I trust him with my life and body.
