I'm pending laminectomy/fusion surgery in June for severe bilateral foraminal stenosis related to spondylolisis/spondylolisthesis. I've come to terms with the face that I really don't have any other treatment options at this point and surgery is my best bet. Having said that, one of my biggest concerns is the potential for this fusion to cause problems (the so-called domino effect) at other levels and require subsequent surgeries. I've been doing some research, but I can't seem to find any definitive statistics/figures on how often single level fusions result in the need for future surgeries/fusions and/or the time frame in which subsequent operations are typically needed.
Anyone have any good references or articles you would suggest?
