Lumbar Spinal Stenosis

Causes of spinal stenosis

There are many potential causes for spinal stenosis, including:
Aging. As you get older, the ligaments (tough connective tissues between the bones in the spine) can thicken. Spurs (small growths) may develop on the bones and into the spinal canal. The cushioning disks between the vertebrae may begin to deteriorate. The facet joints (flat surfaces on each vertebra that form the spinal column) also may begin to break down.
Heredity. If the spinal canal is too small at birth, symptoms may show up in a relatively young person.
Changes in blood flow to the lumbar spine.

Symptoms of spinal stenosis

Pain and difficulty when walking, aggravated by activity.
Numbness, tingling, hot or cold feelings, weakness or a heavy and tired feeling in the legs.
Clumsiness, frequent falling, or a foot-slapping gait.

Diagnosing spinal stenosis

These symptoms also can be caused by many other conditions, which makes spinal stenosis difficult to diagnose. There is usually no history of back problems or any recent injury. Often, unusual leg symptoms are a clue to the presence of spinal stenosis.
If simple treatments, such as postural changes or nonsteroidal anti-inflammatory drugs, do not relieve the problem, your orthopaedic surgeon may request special imaging studies to determine the cause of the problem. An MRI (magnetic resonance image) or CAT (computed tomography) scan may be requested. A myelogram (an X-ray taken after a special fluid is injected into the spine) may be arranged. These and other imaging studies provide details about the bones and tissues and assist the orthopaedic evaluation.

Treatment

Conservative treatment
Changes in posture. People with spinal stenosis may find that flexing the spine by leaning forward while walking relieves their symptoms. Lying with the knees drawn up to the chest also can offer some relief. These positions enlarge the space available to the nerves and may make it easier for stenosis sufferers to walk longer distances.

    Medications. Sometimes the pressure on the nerves is caused by inflammatory swelling. Nonsteroidal anti-inflammatory medication such as aspirin or ibuprofen may help relieve symptoms.

    Rest, followed by a gradual resumption of activity, also can help. Aerobic activity such as bicycling is often recommended.

    Losing weight can also relieve some of the load on the spine.

    When stenosis causes severe nerve root compression, these treatments may not be enough. Back and leg pain may return again and again. Because many stenosis sufferers are unable to walk even short distances, they often confine their activities to the home.

    Lumbar Epidural

    Cortisone injection into the spinal canal can reduce the inflammation around nerves and relieve symptoms. The effects may only be temporary lasing 6 to 9 months

Surgical treatment

If conservative treatment does not relieve the pain, your orthopaedic surgeon may recommend surgery to relieve the pressure on affected nerves. In properly selected cases, the results are quite satisfactory, and patients are able to resume a normal lifestyle
