I had to look up pannus... from what I found on it seems to be arthritis related condition, I linked below so you can read more of it.

[atlantoaxial]
I believe this is the top most 2 cervical spine - atlas /axis or c1 c2.


Was that the only info on the c spine, or did you know what the rest of it meant?
