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 ...
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]
In cervical spondylosis, a patient may be presented with dull neck pain with neck stiffness in the initial stages of the disease. As the disease progresses, symptoms related to radiculopathy (due to compression of exiting spinal nerve by narrowed intervertebral foramen) or myelopathy (due to compression on the spinal cord) can occur.

The joint space equals the distance between the involved bones of the joint. A joint space narrowing is a sign of either (or both) osteoarthritis and inflammatory degeneration. [12] The normal joint space is at least 2 mm in the hip (at the superior acetabulum), [13] at least 3 mm in the knee, [14] and 4–5 mm in the shoulder joint. [15]
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.
The intervertebral disc is removed and replaced with a small plug of bone or other graft substitute, along with a height restoration device to un-impinge nerves, and in time, the vertebrae will fuse together. Intervertebral disc arthroplasty: also called Artificial Disc Replacement (ADR), or Total Disc Replacement (TDR), is a type of arthroplasty.
For example, the height loss was measured by measuring the patient's height while standing straight (with exaggerated curves in the upper and lower back) and again after the patient fixed this issue (with no exaggerated curves), both of these measurements were taken in the morning with a gap of 6 months and the growth plates of the patient were ...
Spinal stenosis is a narrowing of the canal which can occur in any region of the spine and can be caused by a number of factors. It may result in cervical myelopathy [4] if the narrowed canal impinges on the spinal cord itself. Spinal canal endoscopy can be used to investigate the epidural space, and is an important spinal diagnostic technique ...
