Hi. I'm new to this site and this is my first post. I have an T12-L5 fusion that has served me well for many years. The problem is that the L5-S1 site is now failing and I have painful sciatica down the right leg. In the past year the pain has persisted for 4-5 months and then devolved to something manageable. Unfortunately the pain is back and I am searching options for long term relief. Having already had a discetomy at L5, my only surgical option is to complete the fusion of L5-S1. Can anyone tell me the possible limitations of mobility, restrictions of range of motion or limitations of activities I might experience if I choose this option?
