Degenerative Disc
Disease
Degeneration of the intervertebral disc, which is often called "degenerative
disc disease" (DDD) of the spine, is a common disorder
of the lower spine. Disc degeneration can lead to disorders
such as spinal stenosis (narrowing of the spinal canal that
houses the spinal cord and nerve roots; can be lumbar or cervical),
spondylolisthesis (forward slippage of the disc and vertebra),
and retrolisthesis (backward slippage of the disc and vertebra).
DDD is in fact not a disease but, rather, a degenerative condition
that can be painful and can greatly affect the victim's quality
of life. Disc degeneration is a normal part of aging and is
generally not a problem by itself. However, for certain individuals,
a degenerated disc can cause pain, such as when bone spurs
grow adjacent to the discs and pinch or put pressure on the
nearby nerve roots or spinal canal.
Causes
Aging is the most common cause of disc degeneration. As the
body ages, the discs in the spine dehydrate, or dry out, and
lose their ability to act as shock absorbers between the vertebrae.
The bones and ligaments that make up the spine also become
less flexible and thicken. Unlike muscles, there is minimal
blood supply to the discs so they lack the ability to heal
or repair themselves. Repetitive stress injury (RSI) and/or
several injuries over time that involve the same disc can also
increase the likelihood of disc degeneration as may a poor
body mass index. However, an active lifestyle that combines
regular light exercise and a good diet can help to repair or
prolong the life of the disc.
Symptoms
With symptomatic degenerative disc disease, chronic low back
pain sometimes radiates to the hips, or there is an aching
pain in the buttocks or thighs while walking; sporadic tingling
or weakness through the knees may also be evident. Similar
pain may be felt or may increase while sitting, bending, lifting,
and twisting. While the degeneration of the disc will likely
progress as a natural part of the aging process, symptoms such
as low back pain often decrease over time.
Understanding Disc Pain
It is not clear why some degenerative discs are painful and
some are not. After an injury, some discs become painful because
of inflammation. Some people have nerve endings that penetrate
more deeply into the annulus fibrosus, or outer layer of the
disc, than others, making the disc more susceptible to becoming
a source of pain. Pain that radiates down the leg, known as
sciatica or lumbago, is the result of the nerve root encountering
the inner disc material, or the nucleus pulposus, an inflammatory
substance that also puts pressure on the nerve. These conditions
can cause symptoms such as severe leg pain, difficulty standing
and walking, and weakness or numbness in the legs. Degenerative
disc disease can lead to a chronic debilitating condition and
can have a serious negative impact on a person's quality of
life. When pain from degenerative disc disease is severe, traditional
nonoperative treatment is often ineffective.
