Cervical disc herniation
Cervical herniated discs less common than lumbar herniated discs
Cervical disc herniations are far less common than
lumbar disc herniations for two reasons:
- There is far less disc material in the cervical
spine
- There is substantially less force across the cervical
spine
When they do occur, most cervical disc herniations
will extrude out to the side of the spinal canal and
impinge on the exiting nerve root at the lower level
(e.g. C6 at C5-C6) (Figure
1 and Figure
2).
If the space for the nerve root (foramen) is already
compromised because of associated disc space collapse
or bone spurs (osteophytes), the added impingement
of the disc may irritate the nerve root and cause a
radiculopathy (arm pain). If the foramen is not compromised,
the radiculopathy may be temporary and relieved with
conservative treatment.
Treatment options for a cervical herniated disc
In general, most cervical disc herniations will heal
with time and conservative treatment and will not require
surgery. The following includes an overview of:
Conservative treatments for a cervical herniated disc
As in the lumbar spine, the first line or treatment is generally a couple days
of rest and non-steroidal anti-inflammatory drugs (NSAIDs).
If the pain is severe and/or continues for more than
a couple of weeks, oral steroids can be useful to decrease
inflammation. Oral narcotic agents can be added for
severe pain, but should only be taken for a short time
(less than two weeks).
If the pain lasts for more than two to four weeks,
conservative treatments may include:
-
Physical therapy for exercises to help
relieve the pressure on the nerve root
-
Chiropractic treatments for manual manipulation
to help relieve the pressure on the nerve root
-
Manual traction to help open up the cervical
foramen where the nerve root exits the spinal canal.
If this therapy helps relieve the pain, a home
traction unit can be prescribed. Traction should
be initiated under a physical therapist's supervision.
For pain that does not get better with medical and
physical treatments, epidural injections may
be considered. Epidural injections effectively relieve
pain approximately 50% of the time, and if they do
work they may be repeated every two weeks up to a total
of three times within one year.
Surgical treatments for a cervical herniated disc
If 6 to 12 weeks of conservative treatment fails
to relieve the arm pain, then surgical removal of the
disc may be reasonable.
An MRI scan or CT with myelogram can confirm the presence
of a disc herniation and the level that is affected.
If the patients symptoms and neurological deficit
match the results of the scan, surgery is reliable
in terms of relieving arm pain and has a low completion
rate.
The disc may be removed from the back of the neck
(posterior approach) or from the front (anterior approach).
Generally, surgeons favor the anterior approach for
most cervical disc herniations.
-
Anterior surgical approach for a cervical disc herniation may be favored
if there is any disc space collapse, as the approach
allows the surgeon to "jack open" the
disc space and place a bone graft to keep it open.
This procedure opens up the foramen, which gives
the exiting nerve root more room
-
Posterior surgical approach for a cervical disc herniation may be favored
for a large soft disc that is lateral (to the side
of) the canal
Both spine surgeries can usually be done with an
overnight stay in the hospital.
