I am very happy for your father I am glad he is one of the lucky ones. But you said yourself you have heard of more failed fusions. I don't feel I gave any bad medical information, I said to look up and research the artificial disc, as I have heard more positive from this, yet they want to ban it in this country. I only heard they want to ban it from a chiropractor so I do not know if it is true.
Why is this not available worldwide yet?

Disc replacement surgery in Germany
The first artificial disc was developed by a German surgeon in the 1980s. The technology has improved significantly over the years since its invention, and today there are many different types of artificial discs on the market.
German doctors have been leading the way in researching and implementing this relatively new procedure.
The procedure is not yet widely available worldwide, but it is currently available in several spinal centers in Germany, including clinics in the Premier Healthcare Germany network. "
