Such severe spinal stenosis symptoms are virtually absent in lumbar stenosis, however, as the spinal cord terminates at the top end of the adult lumbar spine, with only nerve roots (cauda equina) continuing further down. [15] Cervical spinal stenosis is a condition involving narrowing of the spinal canal at the level of the neck.
Lumbar spinal stenosis (LSS) is a medical condition in which the spinal canal narrows and compresses the nerves and blood vessels at the level of the lumbar vertebrae. Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis. Lumbar spinal stenosis can ...
In addition to spinal stenosis, other lower back conditions such as spondylosis, tumors, infections and herniated or ruptured discs can cause NC. These conditions contribute to the potential narrowing of the spinal cord, increasing pressure and inducing damage on the spinal nerve roots, thus, causing paing, tingling or weakness in the lower body.
At the 4th and 5th lumbar levels, great pressure is said to be exerted on the posterior aspect of each vertebra and transferred from the vertebra to the disc. Williams specified that in most cases the 5th lumbar disc ruptures and the nuclear material of the disc moves into the spinal canal causing pressure on the spinal nerves.
Other symptoms include impaired walking and a slightly stooped posture due to loss of disc height and bulging of the disc. Lumbar spinal stenosis is very prevalent with 9.3% of the general population producing symptoms and the number is continuing to rise in patients older than 60. [16]
Spinal decompression: A non-invasive procedure that temporarily (a few hours) enlarges the intervertebral foramen (IVF) by aiding in the rehydration of the spinal discs. Spinal laminectomy: A procedure for treating spinal stenosis by relieving pressure on the spinal cord. A part of the lamina is removed or trimmed to widen the spinal canal and ...
