Within the spinal column is the spinal canal. The structure of bones and ligaments encases the soft spinal cord and the nerves that run down the legs. So the spinal canal forms a bony protection.
In a narrowing (stenosis) of the spinal canal are also referred to a spinal stenosis. Most of the spinal canal is at the level of the lumbar spine constricted (Lumbar Spinal Stenosis). Affected typically suffer from fatigue and pain in the legs, which strengthen significantly when walking.
What are the causes?
The causes of a narrowed spinal canal can be congenital or acquired. Congenital defects such as malformations vertebrae favor the disease. Most common are wear and tear of vertebrae and inter vertebral discs the cause. Again playing the genes - that is, the genetic material - a certain role. Often occur congenital and acquired causes also combined.
Lumbar spinal stenosis is a very common disease in older ages. For over 60 years there is a narrowing of the spinal canal with every fifth patient.
