    Hello,
    What are the diagnostic images are available to determine c1 c2 accessory ligament and alar ligament injury?

    The best tests for these ligaments are a complete history with the appropriate symptoms, X-rays with flexion/extension, an MRI focusing on the upper cervical spine (some MRIs do not include this area) and possibly flexion/extension limited CT scans. I will tell you it is exceedingly rare to find injury to these ligaments unless significant trauma occurs (ejected out of a car when not wearing seatbelt, motorcycle vs. car impact, fall from substantial height) or you have a metabolic disorder.

    There is a spurious test called the DMX or fluoroscopic video imaging of the neck with motion. I have never found this test to be valid or reliable and I know of no surgeon who uses this test but there are a few non-surgeons who use it.

    DMX is an unknown and “findings” are overcalled by the “rare” radiologists who read these films. The amount of radiation exposure is not called for as the diagnostic benefit is not there for the amount of fluoroscopic time necessary to get motion films. Findings are spurious in my opinion.

    X-rays and an MRI are the best way to diagnose this disorder but do not get too fixed on occiput-C1 instability as a diagnosis as this diagnosis is exceedingly rare.
