  2. Intervertebral disc - Wikipedia

    en.wikipedia.org/wiki/Intervertebral_disc

    The intervertebral disc space is typically defined on an X-ray photograph as the space between adjacent vertebrae. In healthy patients, this corresponds to the size of the intervertebral disc. The size of the space can be altered in pathological conditions such as discitis (infection of the intervertebral disc). [medical citation needed]

  3. Spinal stenosis - Wikipedia

    en.wikipedia.org/wiki/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]

  4. Degenerative disc disease - Wikipedia

    en.wikipedia.org/wiki/Degenerative_disc_disease

    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.

  5. Spondylosis - Wikipedia

    en.wikipedia.org/wiki/Spondylosis

    Cervical X-rays may show osteophytes, decreased intervertebral disc height, narrowing of the spinal canal, and abnormal alignment (kyphosis of the cervical spine). Flexion and extension view of the cervical spine is helpful to look for spondylolisthesis (slippage of one vertebra over another).

  6. Lumbar spinal stenosis - Wikipedia

    en.wikipedia.org/wiki/Lumbar_spinal_stenosis

    Any forward slipping of one vertebra on another can cause spinal stenosis by narrowing the canal. If this forward slipping narrows the canal sufficiently, and impinges on the contents of the spinal column, it is spinal stenosis by definition. If associated symptoms of narrowing exist, the diagnosis of spinal stenosis is confirmed.

  7. Vertebral osteomyelitis - Wikipedia

    en.wikipedia.org/wiki/Vertebral_osteomyelitis

    Vertebral osteomyelitis often attacks two vertebrae and the corresponding intervertebral disk, causing narrowing of the disc space between the vertebrae. [6] The prognosis for the disease is dependent on where the infection is concentrated in the spine , the time between initial onset and treatment, and what approach is used to treat the disease.

  8. Spinal disease - Wikipedia

    en.wikipedia.org/wiki/Spinal_disease

    Lumbar spinal stenosis is classified as a narrowing of the spinal canal in the lumbar region of the vertebrae. This may lead to compression of the nerve root of the spinal cord and result in pain of the lower back and lower extremities.

  9. Cervical spinal stenosis - Wikipedia

    en.wikipedia.org/wiki/Cervical_spinal_stenosis

    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.
