Stenosis Of The Canal

The narrowing of the vertebral or intervertebral canal can cause nerve tissue compression. This pathology, when symptomatic, causes pain especially during walking, which is limited; the flexion or the sitting position give an immediate, even temporary, relief of the pain.There are two types of stenosis of the column canal, one congenital, but quite rare, the other more common and deriving from different causes. This restriction of the central canal or lateral foramen may be due to degeneration of the joints of the vertebrae, a herniated disc hernia, changes in the ligaments around the vertebrae, spondylolisthesis, scoliosis of the spine, scars or adhesions following surgical interventions. This degenerative restriction can cause symptoms, among the most common of this pathology are pain, tingling or numbness especially in the leg, an increase in symptoms with walking and a reduction in leg strength. It generally affects the elderly population in the lumbar spine leading to a history of symptoms in the lower limbs. They are relieved by falling activity and exacerbated by extension, for example the path, and causes a persistent loss of extension. In the cervical spine the symptoms are on the arm and always produced by the closing of the foramen, abolished or decreased with its opening with certain movements or positions. Stenosis can cause a compression on the spinal cord causing a myelopathy, a more serious but also rarer, potentially non-reversible disease.
