No problem
But what you you class as ddd with collapsed disc, you mean when there is nothing of the disc left and the bone is rubbing? I can't see what problem there is otherwise.
I think LP ESP is the best option with 10 years data of implantation, I'm sure there will be models in the future which are "better", but I would have to wait many many years before a new disc had been tested etc for it to be a possibility.
So I hope I find a surgeon I like for LP ESP, and that the disc is suitable for me, as I would really like my life back please
