What is spondylolisthesis?
Spondylolisthesis is a condition in which one bone in your back
(vertebra) slides forward over the bone below it. It most often occurs
in the lower spine (lumbosacral area). In some cases, this may lead to
your spinal cord or nerve roots being squeezed. This can cause back pain
and numbness or weakness in one or both legs. In rare cases, it can
also lead to losing control over your bladder or bowels. See a doctor
right away if you begin losing bladder or bowel control.
Sometimes when a vertebra slips out of place, you may have no symptoms
at all or no symptoms until years later. Then, you may have pain in your
low back or buttock. Muscles in your leg may feel tight or weak. You
may even limp.
What causes spondylolisthesis?
The bones in
your spine come together at several small joints that keep the bones
lined up while still allowing them to move. Spondylolisthesis is caused
by a problem with one or more of these small joints that allows one bone
to move out of line.
Spondylolisthesis may be caused by any of a number of problems with the small joints in your back. You could have:
A defective joint that you've had since birth (congenital).
A joint damaged by an accident or other trauma.
A vertebra with a stress fracture caused from overuse of the joint.
A joint damaged by an infection or arthritis.
Spondylolisthesis affects children and teens involved in sports. Some
sports, such as gymnastics or weight lifting, can overuse back bones to
the point of causing stress fractures in vertebrae, which can result in
Older adults can develop spondylolisthesis,
because wear and tear on the back leads to stress fractures. It can also
occur without stress fractures when the disc and joints are worn down
and slip out of place.
What are the symptoms?
Symptoms of spondylolisthesis may include:
Back or buttock pain.
Pain that runs from the lower back down one or both legs.
Numbness or weakness in one or both legs.
Loss of bladder or bowel control.
Leg, back, or buttock pain that gets worse when you bend over or twist.
Sometimes spondylolisthesis causes no symptoms at all.
How is spondylolisthesis diagnosed?
Your doctor will look at X-rays of your back if he or she suspects you
have spondylolisthesis. X-rays will show if any of the vertebrae in your
back have fractures or cracks and have slipped out of place. You could
also have a CT scan or an MRI to pinpoint the damage and help guide
How is it treated?
spondylolisthesis begins with stopping any physical activity that may
have led to vertebrae damage. To help relieve pain, take nonsteroidal
anti-inflammatory drugs, including aspirin (such as Bayer), ibuprofen
(such as Advil), or naproxen (such as Aleve). Do not give aspirin to
anyone younger than 20 because of the risk of Reye syndrome, a serious
illness. Acetaminophen (such as Tylenol) can also help with pain.
