Coronal section through a severely
degenerated lower cervical spine of a 70–year old female who had
neck pain but no history of radiculopathy or vertebral artery
insufficiency. The spondylosis (degeneration of the "disc joint")
encompasses severe degeneration of the intervertebral discs and
endplate sclerosis especially in the uncovertebral pseudojoints at
which reactive degenerative bone apposition entails ridging which
segmentally displaces the vertebral arteries laterally, causing them
to take an undulating serpiginous course. On both sides the
segmental nerves emerge behind the vertebral artery.
