An intervertebral disc (British English), also spelled intervertebral disk (American English), lies between adjacent vertebrae in the vertebral column.Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae, to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine.
Additionally, the body can react to the closing gap between vertebrae by creating bone spurs around the disc space in an attempt to stop excess motion. [8] This can cause issues if the bone spurs start to grow into the spinal canal and put pressure on the spinal cord and surrounding nerve roots as it can cause pain and affect nerve function.
When the spinal canal diameter divided by vertebral body diameter is less than 0.82, or the anteroposterior diameter of the spinal canal is less than 1.3cm or the distance between the pedicles is less than 2.3cm during imaging, cervical spine stenosis is diagnosed symptoms correlate well with the spinal canal narrowings.

According to a 2008 study, the incidence of discitis in the United States is around 0.4 to 2.4 per 100,000 people each year depending on age group. [5] According to a later 2016 study, the combined prevalence of discitis and vertebral osteomyelitis with or without spinal epidural abscess for persons under 20 years old is uncommon (0.3 per 100,000 persons), and higher in older patients (6.5 per ...
A disc herniation or spinal disc herniation is an injury to the intervertebral disc between two vertebrae, usually caused by excessive strain or trauma to the spine. It may result in back pain , pain or sensation in different parts of the body, and physical disability .
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 ...
Disappointed with the outcome and felt we were one of the 12 best teams in the country. We had an extremely challenging schedule and recognize there were two games in particular that we did not ...
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 ...
