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.
Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [ 6] Symptoms may include pain, numbness, or weakness in the arms or legs. [ 1] Symptoms are typically gradual in onset and improve with leaning forward. [ 1]
Pathological processes that can occur in these joints include degenerative changes or hypertrophic arthritis, resulting in foraminal stenosis and nerve compression. Foraminal stenosis at this joint is the most common cause of cervical nerve root pressure. They were characterized by Hubert von Luschka in 1858. [4] [5]
The intervertebral foramen (also neural foramen) (often abbreviated as IV foramen or IVF) is an opening between (the intervertebral notches of [ 1]) two pedicles (one above and one below) of adjacent vertebra in the articulated spine. [ 2]: 424, 425 Each intervertebral foramen gives passage to a spinal nerve and spinal blood vessels, and lodges ...
Facet syndrome. Facet syndrome is a syndrome in which the facet joints ( synovial diarthroses) cause painful symptoms. [ 1] In conjunction with degenerative disc disease, a distinct but functionally related condition, facet arthropathy is believed to be one of the most common causes of lower back pain. [ 2][ 3]
Neurogenic claudication ( NC ), also known as pseudoclaudication, is the most common symptom of lumbar spinal stenosis (LSS) and describes intermittent leg pain from impingement of the nerves emanating from the spinal cord. [ 1][ 2] Neurogenic means that the problem originates within the nervous system. Claudication, from Latin claudicare 'to ...
Spondylosis. Spondylosis is the degeneration of the vertebral column from any cause. In the more narrow sense it refers to spinal osteoarthritis, the age-related degeneration of the spinal column, which is the most common cause of spondylosis. The degenerative process in osteoarthritis chiefly affects the vertebral bodies, the neural foramina ...
Cervical spinal stenosis. A human vertebral column. Specialty. Orthopedic. Cervical spinal stenosis is a bone disease involving the narrowing of the spinal canal at the level of the neck. It is frequently due to chronic degeneration, [ 1] but may also be congenital. Treatment is frequently surgical.
