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]
Lumbar spinal stenosis can cause pain in the low back or buttocks, abnormal sensations, and the absence of sensation (numbness) in the legs, thighs, feet, or buttocks, or loss of bladder and bowel control. The precise cause of LSS is unclear. Narrowing of spinal structures in the spinal cord such as the central canal, the lateral recesses, or ...
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 ...
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]
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.
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]
Cauda equina syndrome. Cauda equina syndrome ( CES) is a condition that occurs when the bundle of nerves below the end of the spinal cord known as the cauda equina is damaged. [ 2] Signs and symptoms include low back pain, pain that radiates down the leg, numbness around the anus, and loss of bowel or bladder control. [ 1]
