Had L-5, S1 Fusion in 2006 at age 56. The surgery changed my life. I am positive that had I waited any longer to have this surgery I would be in a wheel chair. Dr. Gebhard is the best at what he does. He sets you up to win the battle. It's up to you to follow orders to have a good outcome. My advice for a positive outcome; do what he tells you and walk the maximum allowed to build bone. I thank God for his skilled hands
