One of our members mentioned that after an unsuccessful ES surgery Arcuate Foramina (bridge) was suggested & noted on her CT; ‘Apparently I have an ossified ligament in my C1. As a result, a bony bridge was created “in theory” to protect my Vertebral Artery and SubOccipital Nerve from being compressed.’
But after consulting an expert doctor (who she didn’t name) at UCLA, his opinion was ‘He said it’s very common, sees it all the time, and non-life threatening!!! In fact he said neurologist don’t even order CT scans of the spine anymore because they find so much calcifications and typically they never cause a problem and when they do trust me your body sends off the alarm!!’
So hopefully that’s reassuring?
