Sample images and analysis of the cervical spine:

Example cervical WS Flexion

Initial functional X-ray in Flexion

Landmarks_C3-4_normal

Visualization of the Range of Motion in the segment C3-4 with optional markers (yellow).
The RoM ( = 7.0°) and disk height is normal.

Landmarks_C4-5_week

Altered segment C4-5 (low disk height) with normal Range of Motion (8.9°). Possible reason for the degeneration sign of the disk while showing normal RoM might be the fusion of the segment below.

Landmarks_C5-6_pathological

Heavily altered segment C5-6, Rang of Motion reduced (RoM = 3.1°), fusion of the segment in process.

Example_Cerv_Extension1

and Extension

CoR_C3-4_normal

C3-4 Center of Rotation (green dot in the middle).
Physiologic location in the middle, below the disk space.

CoR_C4-5_week

The CoR of C4-5 (green) is within the physiologic range. Large translations of the landmarks LM3 and LM4 (left) in relation to the fixed marker suggest large strains, which are likely to accelerate the degeneration of the Anulus Fibrosus.

CoR_C5-6_pathological

Pathologic location of the C5-6 Center of Rotation (green).
Indicates, together with the reduced RoM, towards a progressing fusion in this segment.
