Not overanalyzing at all. I had it done in June of 2022. I know a person who had a spacer installed at a much younger age and he said it fixed his problem and he is not in his 90's. Does not mean it is right for you. I did a lot of research and decided to do it as it seems to be (and was) a fairly simple procedure that took about 30 minutes. I was mildly sedated ( like a colonoscopy) and I could actually feel the surgeon hammering it in but no pain. The results have been neutral to minor improvement. Hoping will prevent worsening. Kinda made sense to me.
