I had a very sore neck the other day - the pain radiated from the middle of my neck out to the sides. The doctor in the emergency room did a scan and said I had crowned dens syndrome. I've never heard of that. What is it?
Crowned dens syndrome is a syndrome that results from the build up of calcium around on the second vertebrae in your neck. The first vertebrae rotates on a small finger-like or tooth-like projection called the odontoid process.

When calcification occurs around this projection, it causes pressure and pain in your neck. Luckily, it can be treated and the pain usually resolves within a few days.
