Spinal stenosis is otherwise known as spinal cord arthritis. When the backbone narrows, it puts strain on the spinal cord and also on the nerve roots. Spinal stenosis affects the gaps between the bones of the spine, the tubes in the central column and the nerve base canal that expands from the spinal cord. A patient suffering from spinal stenosis feels pain in the neck, shoulders or neck. He is also likely to suffer from lack of feeling in those areas.

The spinal canal can be compared to a tunnel that runs down the spine. This canal is protected on the outside by blocks of bone called vertebrae. They contain the spinal cord and the nerves that run from the brain to all areas of the body.
Spinal stenosis is caused when the spinal canal narrows due to degenerative changes in the spine. Numbness, tingling, weakness, severe pain and even paralysis can be a result of this disease. Herniated discs, tumor, fracture of the spine, degeneration and infection can cause the spine to narrow. The preliminary symptom of spinal stenosis commonly includes a feeling of heaviness, pain and weakness with walking, sitting or standing for a long time. After a bit of rest, the symptoms usually disappear. When the nerves in the spinal canal are irritated by prolonged walking and standing, the symptoms worsen.
Patients who suffer from spinal stenosis often complain that they need to frequently rest their legs and report a gradual decrease in their ability to walk. The treatments for spinal stenosis vary depending on how severe the symptoms are. Aerobic activities combined with weight loss and a guided exercise program is recommended as the first option.
If there is no significant improvement, injection treatments are recommended. When the symptoms are progressive and severe, and when a specific area of stenosis or narrowing of the spinal canal has been discovered, spinal stenosis surgery is the ideal option. Surgery for spinal stenosis is aimed at removing pieces of bone and thickened tissues to free up the nerves.
Traditional open back surgery to treat spinal stenosis is an invasive procedure. Whether it is a lumbar stenosis surgery or cervical stenosis surgery, the traditional method requires a a large incision and an extensive recovery period. But now, spinal stenosis surgery can be done arthroscopically to achieve the same effects. Arthroscopic laser surgery for spinal stenosis is minimally invasive. Through a small opening of just about ¾ of an inch in width, the surgeon removes offending pieces of bone and tissue that causes stenosis of the spine.
Surgery for spinal stenosis has a very high rate of success in patients who are carefully selected for this procedure. Arthroscopic spinal stenosis surgery when performed by skilled surgeons can provide considerable relief to all the problems caused by narrowing of the spinal cord. A foraminotomy or laminotomy decompresses the spine. When the neural structures are freed, pain and other symptoms disappear.
Treatments for spinal stenosis have become less invasive and more effective through the years. Patients suffering from back pain due to spinal canal narrowing no longer have to consider the invasive open back lumbar stenosis surgery or cervical stenosis surgery when they have a superior and less invasive alternative using arthroscopic means.
