Cervical Spine
The cervical spine is the most mobile section of the spinal
column, and has to support the weight of the head for most
of our waking lives; it is prone to degeneration (wear and
tear), of the intervertebral discs and the seven facet joints
on each side of the spine. These degenerative changes
may result in pressure on the spinal cord, or cervical nerves
which can in turn cause pain in the upper limb, or weakness
and numbness in the legs.
Disc protrusion
A cervical disc protrusion may be due to a sudden movement
or injury, such as the whiplash injury which can be sustained
in a road traffic accident. The disc protrusion may
cause pain in its own right or it may cause pain by pressing
on the cervical nerve roots, as they leave the spinal canal.
More seriously, a cervical disc which protrudes posteriorly
may press on the spinal cord and cause weakness of the legs
or sphincter disturbance (incontinence).
