I also have a retroflexed odontoid with a lot of pannus (if I’m interpreting my brain MRI correctly). I have not looked at my c-spine or rest of my spine yet.
(Barbara, I realized today that the MRI image I sent you was not the middle slice. The green circle part you saw seems to be pannus, but the odontoid is only visible in the middle slice.)
I read other posts of Barbara’s about using the hard collar instead of soft. I am feeling like the hard collar could be worse on my out of place neck. I believe when my head is in its usual position, my odontoid and cervical vertebrae are pressing less on my dura. If I use a collar to reposition my head into normal position, it would be pressing more.
Update… decided to order a Philadelphia and see how it feels. I know most others will be too soft.
