I find it interesting,because I have a patient who had Dynesys which was starting to fail, revision surgery was done and it was replaced with 2 level ADR done from an anterior position as usual. That is over six months ago and I await an e-mail to hear how they are progressing.
Revision surgery can be done, but it's very dangerous, and requires a lot of competence from the medical team
