This can replace most fusions and it is easier to perform and it doesn't have to fuse. It is available in the free world.
Neo Disk only requires four screws. It is minimally disruptive.
There are even better ways of doing it such as implanting it and then pumping in the silicone or a safe hydrogel. It will do everything a fusion can do but it will also do everything a real disk can do.
As to infections: There is no reason other than criminal neglect for even a single nosocomial infections to occur. They are 100% preventable. Greed and carelessness are why they occur and infect over 2 million Americans each year and kill over 100,000.
