What Is Spinal Stenosis?
Spinal stenosis is a condition in which the spinal canal narrows and pinches the nerves.
The spinal canal contains the nerve roots and spinal cord. Depending on where the
narrowing occurs, pain may be felt in the lower back, legs, neck, shoulders, or arms.
In adults ages 50 and older, the risk of developing spinal stenosis increases. Younger
people who are born with a small spinal canal may also develop symptoms. Aging can
cause the tissues that connect the spine and bones (ligaments) to become thicker and
calcified. The disks between vertebrae break down. Growths called bone spurs may happen
on bones and into the spinal canal. Degeneration may also lead to curvature of the
spine. All of these conditions tighten the spinal canal. This causes spinal stenosis.
Symptoms of spinal stenosis may include:
Back and leg pain
Tingling feeling in feet and legs
A hot or cold feeling
A heavy, tired feeling in the legs
Clumsiness or frequent falls
Often, bending forward will lessen the pain, such as by leaning onto a shopping cart
at the grocery store.
If you notice any of the above symptoms, talk with your healthcare provider.
If you notice any symptoms, talk with your healthcare provider. They may advise treatment,
Surgery is considered after other treatments have not improved symptoms, and when
the benefits of surgery are greater than the possible risks. In some cases, surgery
may be urgently needed due to severe weakness or loss of bowel and bladder function.
Common procedures used for this condition are:
Decompression (laminectomy). This surgery removes the bone and soft tissues of the spine that are pinching the
Spinal fusion. This surgery is done when there is a contributing deformity of the vertebra or curvature
of the spine. It permanently fuses 2 or more vertebrae together. A piece of bone,
often taken from the hip, is used to complete the fusion. Screws and rods may be used
to hold the bones together while they mend. This can also speed recovery time.
No matter your age or your physical ability, prevention should be a main focus. This
Staying physically fit and getting regular exercise. This can help lead to a healthier spine by improving endurance and strengthening
the back muscles.
Staying at a healthy weight. This reduces the load placed on the spine.
Not smoking. Smoking may help lead to the spine breaking down faster than the normal aging process.
