The Blair model of upper cervical misalignment....

The animations presented here were developed using 3D Studio MAX animation software on an MS-DOS compatible PC using spinal data from Viewpoint Datalabs. They are in Windows Animation format (.AVI) and can be displayed with the Media Player application. The Media Player viewer allows you to scale the image on screen, play the animations one frame at a time, and copy individual frames to the clipboard for transfer to other graphics applications.

When you click on one of the files for download, your browser will probably load the image and let you run the animation from the browser. For repeat viewing, use the browser to save the file to your hard drive. (File|Save As).

A note about file sizes: these files were rendered at either 640x480 or 512X400 resolution in 256 colors. The size of the files ranges from about 950Kbytes to 1.4 Megabytes. If your Internet connection is via MODEM, download times may be excessive.


Occipito-Atlantal Misalignment


    In the Blair model, the atlas is displaced so that one codyle is 'tracking' or moving along the occipital condyle. The opposite condyle must 'slip', so that an overlap is seen. In this inferior view, the condyle on the right is tracking, and the left one is slipping. Solid model
X-ray model
Blair practitioners use a special x-ray view to image the tracking and slipping condyle, the 'Condylar View'. This animation is staged to show the view looking down the tracking condyle on the right. Notice the overlap that occurs on the slipping condyle on the left side of the image. Solid model
X-ray model
The lateral view of the same misalignment pattern. Note the Superior/Inferior (Flexion/extension) motion that accompanies the movement. Solid model

C2-C3 Misalignment


   The C2-C3 misalignment is ... This animation shows C2 and C3 abnormal movement from the posterior Solid model
Blair practitioners use a stereo view to the decide whether C2-C3 is misaligned, and which posterior joint is the problem. This view shows the movement of C2-C3 from the side. X-ray model
