Intervertebral Discs
The intervertebral dics are little pads that
lie between the vertebrae; each disc has a
tough outer ring (annular fibrosis) and a
soft gel-like center (nucleus pulposis).
The discs separate the vertebrae and,
because they’re knitted into the bones, also
join them together. They act like little
shock absorber’s, cushioning the bones so
that they don’t crash against each other as
we walk, which would be very painful. Discs
help give the spine its curve, flexibility,
and strength. The 23 discs in our spine also
make up about 1/3 of the length of the
spinal column and that’s why we are about a
quarter-inch to a half-inch taller in the
morning than we were the night before; the
discs flatten out a little after a day of
standing and then regain their volume when
we sleep.
Disc Herniation, Protrusions and
Prolapse:
There
two types of herniations: Protrusions and
Prolapses. A protrusion can occur if the
nucleus pulposi bulges, pushing the annular
fibrosis out of shape. A prolapse occurs if
the nucleus bulges out so much that it
actually separates from the rest of the
disc.
If the prolapsed disc goes into the spinal
cord or puts pressure on nerves, it may
cause severe pain that could make sitting,
standing, walking, lifting, urinating,
defacating, sneezing, coughing and moving
nearly impossible. In extreme cases, foot or
leg numbness or a loss of muscle control may
occur. Fewer than 5 percent of those with
low-back pain have any disc problems.
Back Surgery:
While spinal surgery is sometimes necessary,
especially in cases of trauma or severe
bone, disc, and nerve destruction (due to
variety of causes, from infection to
cancer), the vast majority of people with
low-back pain and / or sciatica never need
it.
