I was T -2 dexa when I had 2 level lumbar surgery. The surgeon was stunned that a 40yo male could have lousy bone like that. From what I was told the cut off in Germany is about -2. After that they suggest fusion. My surgeons comment was that my bone was "pretty soft". I ended up with 1 of 2 levels fused and the other was a close call but got a ADR. It worked out good and I am more flexible then I was for years before. I used to dance in ballroom competitions but had to give that up long ago due to these problems. Today I sometimes feel I could do it again but I think I am getting to old
