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 ...
Cervical spinal stenosis is one of the most common forms of spinal stenosis, along with lumbar spinal stenosis (which occurs at the level of the lower back instead of the neck). Thoracic spinal stenosis, at the level of the mid-back, is much less common. [2] Cervical spinal stenosis can be far more dangerous by compressing the spinal cord.
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 ...
Primary spinal tumors begin in either the spinal cord or spinal column, whereas secondary spinal tumors begin elsewhere and spread to the spinal region. [25] Symptoms for spinal tumors may vary due to factors such as the type of tumor, the region of the spine, and the health of the patient.
Compression of the upper spinal cord, multiple sclerosis, transverse myelitis, Behçet's disease, osteogenesis imperfecta In neurology , Lhermitte phenomenon , also called the barber chair phenomenon , is an uncomfortable "electrical" sensation that runs down the back and into the limbs.
This contributes to narrowing the spinal canal and compressing the spinal cord in the corresponding region. Herniated disk due to tearing of the spinal disk over time, causes the disk to protrude and exert pressure on surrounding spinal nerve tissue. Consequent compression on the spinal cord at the cervical region causes CSM. [12]
Subacute combined degeneration of spinal cord, also known as myelosis funiculus, or funicular myelosis, [1] also Lichtheim's disease, [2] [3] and Putnam-Dana syndrome, [4] refers to degeneration of the posterior and lateral columns of the spinal cord as a result of vitamin B 12 deficiency (most common).
