The lumbar spinal canal is the space inside the lower spine that carries nerves to your legs. It is very narrow. Over the course of many years, the bone and tissue around the canal grow, causing the canal to become even more narrow over time. This squeezing may cause back pain, leg pain, weakness, and numbness. Lumbar spinal canal stenosis is not the same as a ruptured disk. Sciatica usually causes back pain that shoots down one leg along the path of the sciatic nerve.

How Central Canal Stenosis Affects the Spinal Cord
Lumbar stenosis is an increasingly common pathological condition that is becoming more frequent with increasing mean life expectancy, with high costs for society. It has many causes, among which degenerative, neoplastic and traumatic causes stand out. Most of the patients respond well to conservative therapy.
Symptoms of lumbar spinal canal stenosis
Spinal stenosis is the narrowing of one or more bony openings foramina in the vertebrae of the spine. When spinal stenosis occurs in the spinal canal, it is called central canal stenosis and may cause compression of the spinal cord. Central canal stenosis can occur in the lumbar lower spine.
Spinal stenosis is the narrowing of the bony canals through which the nerves and spinal cord pass. Arthritis can cause the facet joints and ligaments to enlarge and thicken, restricting the space for the nerves to move freely. The pinched nerves become inflamed and cause pain, cramping, numbness or weakness in your legs, back, neck, or arms.
