I also had surgery there in Nov 07. Can honestely say that it was the worst experience of my life. The operation was a complete failure. It did seem to help a month or so then the steriods that they injected during the surgery wore off and I was back to where I was before surgery. I also had to put up 30k but was assured by LSI that I would be fully reimbursed. After over two years of fighting with ins received only about 6k. I asked LSI about their assurance that I would be reimbursed. They basically told me tough luck and would refund nothing. The 30k was my retirement fund. Before I realized how I had been taken I regretfully told a friend of mine about them. His financial results were similar to mine but his physical results were even worse. Had to have a three level fusion shortly after their procedure. Hope anyone that reads this will stay away. Bloomberg news recently did a story on them that hopefully will help expose them for what they are. I could go on and on about my nightmare with them but will leave it here. There certainally is a reason for the hundreds of complaints on this and the many other sites concerning them. Their PR department does a good job but how they treat their desperate patients will catch up with them eventually.
