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 ...
This condition is called spinal stenosis. For women, there is evidence that menopause and related estrogen-loss are associated with lumbar disc degeneration, usually occurring during the first 15 years of the climacteric. The potential role of sex hormones in the etiology of degenerative skeletal disorders is being discussed for both genders.
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.
There is an association between intervertebral disc space narrowing and lumbar spine pain. [24] The space between the vertebrae becomes more narrow, resulting in compression and irritation of the nerves. [25] Spondylolithesis is the anterior shift of one vertebra compared to the neighboring vertebra. It is associated with age-related ...
This narrowing can be caused by bone spurs, spondylolisthesis, inflammation, or a herniated disc, which decreases available space for the spinal cord, thus pinching and irritating nerves from the spinal cord that become the sciatic nerve. [15] This is the most frequent cause after age 50. [13]
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 ...
Poor postures and loss of the normal spinal curves can lead to spondylosis as well. Spondylosis can affect a person at any age; however, older people are more susceptible. [9] Degeneration of the intervertebral disc, facet joints, and its capsules, and ligamentum flavum all can also cause spinal canal narrowing. [8]
Vertebral osteomyelitis often attacks two vertebrae and the corresponding intervertebral disk, causing narrowing of the disc space between the vertebrae. [6] The prognosis for the disease is dependent on where the infection is concentrated in the spine , the time between initial onset and treatment, and what approach is used to treat the disease.
