Hey...Did anyone catch the re-run episode of CSI on the Spike channel last night? The first case (body) had an artificial disc at L4-5. The coroner was talking about what it was made of and the size and that it was still in clinical trials. It must have been awhile ago because he also mentioned that only 1000 have been implanted in the states. It looked an awful lot like the Charite disc. It was neat to see on a tv show.
