I currently have a grade 2 Isthmic Spondylolisthesis due to a complete separation of the pars interarticularis with a complete deterioration of the L5-S1 disc and a small bulge in the L4-L3. My L5 is currently bone on bone with my S1. The L5 vertebral body measures 40mm in the front and 31mm on the facet side due to wear and compression over the last 5 years. I'm being told the most likely current fix is fusion of the L5-S1 or L4 to S1. However, most of my research shows over time the presiding discs start to degenerate very quickly.
I'm 34 and very athletic. I’ve currently exhausted the nonsurgical management of pain other than Laser Therapy, and now I’m to the surgical point. My goal is to be able to return to my current activities after surgery. I’ve been researching alternative surgery for fusion.
A friend of mine just had disc surgery and showed me the Texas Back Institute's complete disc replacement procedure. This got me thinking about other options to fusion. I was curious if there was a mechanical way to bind the facets back to the vertebral body and replace the L4-L5 and L5-S1 discs, in lieu of fusion. With my issue, I understand my L5 vertebral body would require some type of correction for the loss in shape, but if little to no remolding of the facets has occurred this might be an option.
I was looking to see if anyone has heard of any procedures similar to this being done or even if this is plausible. I have found anything like this. In theory with the right hardware to hold the facets in place, this logically could be an option.
My other thought was, if a fusion of the L5 and S1 is required, then the replacement of the L5-L4 and the L4-L3 discs could give enough support to prevent the presiding discs from deterioration.
