I went through my image discs and found these before and after shots of almost the same angle/section. Pretty cool to see. I think my L4-5 disc was shorter on the left side and this explains why Mr. Boeree had some difficulty in his approach from the left-front, squeezing his disc excising instruments into the space. I think it is also why I feel the most pain and weirdness on my left side around the sacro joint now. It’s the side adjusting to the biggest change. There is also a noticeable change in foraminal volume between the two films.
