Spinal stenosis is an abnormal narrowing (stenosis) of the spinal canal that may occur in any of the regions of the spine. This narrowing causes a restriction to the spinal canal, resulting in a neurological deficit.Symptoms include pain, numbness, paraesthesia, and loss of motor control.horacic spinal stenosis, at the level of the mid-back, is much less common. In lumbar stenosis, the spinal nerve roots in the lower back are compressed which can lead to symptoms of sciatica (tingling, weakness, or numbness that radiates from the low back and into the buttocks and legs).

Spinal stenosis is a disorder that is caused by a narrowing of the spinal canal. This narrowing happens as a result of the degeneration of both the facet joints and the intervertebral discs. In this condition, bone spurs (also called osteophytes) grow into the spinal canal.tenosis may occur in the central spinal canal (central stenosis) where the spinal cord or cauda equina are located, in the tract where the nerve root exits the central canal (lateral recess stenosis), or in the lateral foramen (foraminal stenosis) where the individual nerve roots exit out to the body.

With spinal stenosis, the spinal canal is narrowed at the vertebral canal, which is a foramen between the vertebrae where the spinal cord (in the cervical or thoracic spine) or nerve roots (in the lumbar spine) pass through.horacic spinal stenosis, at the level of the mid-back, is much less common. In lumbar stenosis, the spinal nerve roots in the lower back are compressed which can lead to symptoms of sciatica (tingling, weakness, or numbness that radiates from the low back and into the buttocks and legs).

Spinal stenosis is a narrowing of the open spaces within your spine, which can put pressure on your spinal cord and the nerves that travel through the spine to your arms and legs. Spinal stenosis occurs most often in the lower back and the neck.While spinal stenosis may cause no signs or symptoms in some people, other people may experience pain, tingling, numbness, muscle weakness, and problems with normal bladder or bowel function.Spinal stenosis is most commonly caused by wear-and-tear changes in the spine related to osteoarthritis.In severe cases of spinal stenosis, doctors may recommend surgery to create additional space for the spinal cord or nerves.pinal stenosis is most commonly caused by wear-and-tear changes in the spine related to osteoarthritis.

This topic is about spinal stenosis of the lower back, also known as the lumbar area. If you need information on spinal stenosis of the neck, see the topic Cervical Spinal Stenosis. Lumbar spinal stenosis is a narrowing of the spinal canal in the lower back, known as the lumbar area.This usually happens when bone or tissue-or both-grow in the openings in the spinal bones. This growth can squeeze and irritate nerves that branch out from the spinal cord.umbar spinal stenosis is a narrowing of the spinal canal in the lower back, known as the lumbar area.

1 Spinal stenosis pain in the neck is called cervical spinal stenosis. 2  This condition means that there is potential compression of the spinal cord. 3  Unfortunately, the spinal cord compression can lead to serious problems such as extreme weakness, or even paralysis.n the medical field, stenosis means the abnormal narrowing of a body channel. When combined with the word spinal, it defines a narrowing of the bone channel occupied by the spinal nerves or the spinal cord. Cervical spinal stenosis is rarer and more dangerous than lumbar spinal stenosis.

Pressure on the lower part of the spinal cord or on nerve roots branching out from that area may give rise to pain or numbness in the legs. Pressure on the upper part of the spinal cord (that is, the neck area) may produce similar symptoms in the shoulders, or even the legs (see figs.1, 2, and 3).or example, cauda equina syndrome is a severe, and very rare, form of spinal stenosis. It occurs because of compression of the cauda equina, and symptoms may include loss of control of the bowel, bladder, or sexual function and/or pain, weakness, or loss of feeling in one or both legs.

The most common symptom of spinal stenosis is pain, numbness and/or tingling in legs that is pronounced when standing or walking. Leg pain and numbness may inhibit walking and the spine may lose the lumbar curve and appear flat.pinal stenosis fundamentals. With age, the spinal canal – located in the lower back – can narrow, resulting in spinal stenosis. The narrowing process, which is gradual, reduces the space available for the spinal cord and nerves.
