I just received my medical report back from my orthopedic surgeon and there is something that I don't understand - he states in his report that I have Grade I Spondylolisthesis which is the least. He does report that since my exam I'm totally disabled. I know I'm not able to move around at all but Grade I doesn't seem to equal how I feel. Can you be Grade I and be totally disabled?

I realize that you're not a medical doctor but I could use some insight in this. thanks, John
