Hi Maxine, I'm a new member and just happened upon this site when I was looking up info. on retroflexed odontoid with pannus formation when one of your postings came up. I was quite amazed when I readyour symptoms and diagnosis's which are almost identical to mine. I think it would be advantageous to contact one another to compare are cases and see what we can learn. Let me know what you think. Shawnee
