Buckl,

You do not have the x-ray reading skills to accurately diagnose this instability. Most chiros don't. Upper cervical chiros (NUCCA, Atlas Orthogonal, and Blair) take very specific x-rays to see the misalignment. An ortho-specialist radiologist may if he/she has the training and fine skills to see it. Whether the ligaments are loose is another issue. That may be able to be palpated and manipulated.

The Prolotherapy suggested is a process where an injection of an adjutant is made. This creates a healing response. This will only work if 1. You have the instability. 2. You can maintain good neck posture to keep atlas/axis in proper position. It takes weeks for the ligaments to strengthen and tighten.

If this is your problem, it is well worth the effort to heal this. I had such a problem and it took me years to fully heal.

My best to you.
