  2. Facet syndrome - Wikipedia

    en.wikipedia.org/wiki/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.

  3. Bertolotti's syndrome - Wikipedia

    en.wikipedia.org/wiki/Bertolotti's_syndrome

    Bertolotti's syndrome is characterized by sacralization of the lowest lumbar vertebral body and lumbarization of the uppermost sacral segment. It involves a total or partial unilateral or bilateral fusion of the transverse process of the lowest lumbar vertebra to the sacrum, leading to the formation of a transitional 5th lumbar vertebra.

  4. Facet joint arthrosis - Wikipedia

    en.wikipedia.org/wiki/Facet_joint_arthrosis

    Facet joint arthrosis is an intervertebral disc disorder. The facet joints or zygapophyseal joints are synovial cartilage covered joints that limit the movement of the spine and preserve segmental stability. In the event of hypertrophy of the vertebrae painful arthrosis can occur. [1]

  5. Spondylosis - Wikipedia

    en.wikipedia.org/wiki/Spondylosis

    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. [2]

  6. Lumbar spinal stenosis - Wikipedia

    en.wikipedia.org/wiki/Lumbar_spinal_stenosis

    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.

  7. Facet joint - Wikipedia

    en.wikipedia.org/wiki/Facet_joint

    For example, the facet joint between T1 and T2 is innervated by C8 and T1 medial branch nerves. Facet joint between L1 and L2; the T12 and L1 medial branch nerves. However, the L5 and S1 facet joint is innervated by the L4 medial branch nerve and the L5 dorsal ramus. In this case, there is no L5 medial branch to innervate the facet joint.

  8. Disc herniation - Wikipedia

    en.wikipedia.org/wiki/Disc_herniation

    The majority of disc herniations occur in the lumbar spine (95% at L4–L5 or L5S1). [21] The second most common site is the cervical region (C5–C6, C6–C7). The thoracic region accounts for only 1–2% of cases.

  9. Spinal stenosis - Wikipedia

    en.wikipedia.org/wiki/Spinal_stenosis

    Such severe spinal stenosis symptoms are virtually absent in lumbar stenosis, however, as the spinal cord terminates at the top end of the adult lumbar spine, with only nerve roots (cauda equina) continuing further down. [15] Cervical spinal stenosis is a condition involving narrowing of the spinal canal at the level of the neck.
