Cervical spine alignment

When assessing cervical spine alignment, look for four parallel lines connecting structures in the cervical spine:

  1. anterior vertebral line: anterior margin of the vertebral bodies
  2. posterior vertebral line: posterior margin of the vertebral bodies
  3. spinolaminar line: posterior margin of the spinal canal
  4. posterior spinous line: tips of the spinous processes

These lines should follow a slightly lordotic curve, smooth and without step-offs. Any malalignment should be considered evidence of bony or ligamentous injury.
