1. Complex cervical spinal deformity. Cervical kyphosis is associated with posterior spinal cord compression at C2 to C4 and anterior spinal cord compression C4 to C6.

2. Severe multilevel cervical spinal stenosis due to anterior and posterior cord compression.

3. Single-level cervical disc extrusion associated with severe spinal cord compression.

4. Multilevel cervical spondylosis superimposed on developmental stenosis. The anteroposterior diameter of the central spinal canal is narrowed on a developmental basis from the C3-C4 level and distally. A cervical disc protrusion is noted at C3-C4, and spondylotic ridges cause mild cord impingement at C4-C5 and C5-C6.

5. Single-level cervical disc protrusion associated with mild spinal cord compression.

6. Congenital stenosis of the cervical spinal canal associated with multilevel disc protrusions and severe multilevel spinal cord compression. Congenital fusion of the C6 and C7 vertebral bodies is noted.
