And then you have to wonder how many operations are done just to bill insurance companies money. I have injured my shoulder(here in the UK) and I saw a specialist shoulder surgeon who basically said that the state of the art research into these kinds of injuries is to just leave them alone and let them heal - but if you were in the US you would have had two operations on it already because they just love operating on things that don't need operating on for dubious medical benefit because they would charge 100k for each operation, easy.
