Yes. I have that too with lost space between so it just sits precariously over the other out of line, and a lot more going on there all around it. I was diagnosed with that and a 27 degree curve offset to the back right there 14 years ago. I went to PT and have done those exercises fairly regularly 4 days a week to strengthen the support muscles to keep it in place. It hasnt self fused yet. I didnt opt for surgery because the PT works for the pain as long as i do it often. I had a friend have surgery on one if ger lumbar around that time, one level fusion and came out of surgery in complete loss of feeling and function in one leg. She was released from the hospital to a rehab home for 3 months to try to regain it and be taken care of while learning to use a walker. She was just 52 at the time. That was enough for me to keep up with the PT to avoid surgery. It's live-with-able if you're determined and committed. All that PT, the listhesis still there, the curve is straightened to less than 10 degrees now due to strengthening the muscles in the area. 😌🙏
