I want to take this opportunity to thank everyone for what has been 10 days of incredibly insightful and constructive discussion. I wanted to thank the authors for taking the time to explain the details of their findings, and I also wanted to extend a big thank you to the experts and my co-moderator Derek for providing thoughtful commentary.
As alluded to by Drs. Benzel and Rampersaud, I completely agree that the major take home points from these two studies is that they represent a shift towards considering more unbiased data in the decision-making process for degenerative spondylolisthesis. Although the findings of these studies cannot be considered definitive, they represent strong steps towards carefully studying and evaluating the surgical decision-making process as it pertains to this disease. Further research (e.g. Swespine) will certainly add to the current body of research on fusion but can also provide more clarity on related concepts of instability, reoperation, and cost-effectiveness. I look forward to observing the evolution of degenerative spondylolisthesis management in the near future.
Thank you to all for sharing your thoughts and ideas.
