I have had the LT cage procedure with pedicle screws and INFUSE bone graft. If it had not been for these forums I would have thought my problems were just normal results of having a fusion. I kept wondering why I still have to take pain meds every day for over 2 years, since when I had a cervical fusion with bone out of my hip was a piece of cake.I have been reading about people who are having to have revisions because of too much bone growth and scar tissue. The FDA has not warned Dr.'s about using this in the lumbar ( only cervical),because people are just now realizing that's their problem. If it's not reported to the FDA then they have no way of knowing about it. Please, anyone who is still having pain- get checked out with a spect ct scan and report it to the FDA if you find too much bone growth etc.When they use your own bone this cannot happen. I worry about all the new patients who will go through this pain. I am not saying that everyone has these results, but I think it's enough for the FDA to take a look at and stop until they know more. They even hinted that when tested on rats that it could have a carcinogenic connection.
