Investigations for Atlas subluxation

As a rule the difference in alignment between the base of the skull and the atlas is visible on plain X-ray, especially on an open mouth view of the atlas. The features are subtle,  and easily mistaken for a projection error on the X-Ray.

A CT scan that covers the base of the skull and the whole of the neck will clearly show the condition. If a patient is properly positioned for a cervical spine CT scan what will be demonstrated will be the skull pointing nose up with the axis of the nose at 90 degrees to the base of the film, with the transverse axes of the vertebrae C2-C7 lying parallel to the base of the film. The atlas will be seen to be lying obliquely with the axis between the transverse processes of the atlas lying between 5-15degrees away from the transverse axes of the other cervical vertebrae. Patient positioning can be awkward in patients with marked thoracic curvature, leading to difficulty in interpreting films.

Radiological investigation also has the benefit of assessing for  any condition that could be a contraindication for any physical work being done on the neck. A full list of the significant contraindications can be found at   Atlantotec is a further new technique recently developed in Switzerland, and is very similar to Atlas Profilax.

    Are your symptoms still resolved? Have you noticed any complications?

    • Yes Michael.
      The key symptoms remain resolved.
      Correcting my posture, and becoming fit and mobile has been a challenge- and I have had other transient symptoms from viryually every other part of my back as I go down the path. However- there is real, and continuing improvement.
      In the last 2 years I seem to have lost 10 years of physiological age.
      The blog needs more work- and this will be done over the holidays.

  2. Nice post. I learn something totally new and challenging on
    websites I stumbleupon everyday. It will always
    be helpful to read content from other authors and use a little something
    from their sites.
