I was in back pain for 15-years. Dr. Keenen, preformed a lumbar fusion on L4/L5. This was my 2nd surgery on my back and I was very concerned if a second surgery would help. After evaluating my RMI, Dr. Keenen, called me ( That was a new experience. Having the Dr. call me), and I was able to have a Q & A about my condition, and concerns.
