Anterior Cervical Diskectomy |
What is it?
Anterior cervical diskectomy is an operation performed on the upper spine to relieve
pressure on one or more nerve roots, or on the spinal cord. The procedure is explained by
the words anterior (front), cervical (neck), and diskectomy (cutting out the disc).
Why is it done?
Neck and arm pain, among other symptoms, may occur when an intervertebral disc
herniates. This happens, either suddenly with injury or slowly over time, when some of the
disc's jelly-like center (the nucleus pulposus) bulges or ruptures through its tough,
fibrous outer ring (the annulus fibrosus) and presses on a nerve. When a disc ruptures in
the cervical spine, it puts pressure on one or more nerve roots (often called nerve root
compression) or on the spinal cord. This pressure causes symptoms in the neck, arms, and
even legs. Further pressure may be caused by rough edges of bone, called bone spurs, that
naturally build up around some herniated discs.
In this operation, the cervical spine is reached through a small incision in the front
of your neck. After the soft tissues of the neck are separated, the intervertebral disc
and bone spurs are removed. The space left between the vertebrae may be left open or
filled with a small piece of bone. In time the vertebrae may fuse, or join together.
If used, the pre-formed bone graft may be obtained from a bone bank. It will not be
rejected by your body, because it is avascular (contains no blood cells). In some
circumstances, or if your surgeon prefers, the bone graft might instead be removed from
your own hip through a second incision.
