Lateral view of cervical single-level vertebral spontaneous fusion.
A, Fusion of the vertebral bodies and the zygapophyseal joints, where the spinous processes remained independent; B, Fusion of the vertebral bodies, the zygapophyseal joints, and the spinous processes.
Figure 2.
Measurements of cervical spine lengths were made by locating seven points and connecting each point in-sequence.
Figure 3.
Definitions of the fused vertebrae and adjacent vertebrae.
Figure 4.
Spinal canal index is equal to the sagital diameter of the spine canal divided by the anterior-posterior length of the body, at its mean point.
Figure 5.
The translational instability of the adjacent vertebra was measured as the distance between the superior/inferior point of the posterior L1/U1 vertebral body from the extended line of the posterior U0-L0 vertebral margin.
