  2. Spondylolisthesis - Wikipedia

    en.wikipedia.org/wiki/Spondylolisthesis

    Degenerative spondylolisthesis at L5-S1. (A) CT sagittal view of a low grade slip. (B) Lateral radiograph pre-operative intervention. (C) Surgically treated with L5S1 decompression, instrumented fusion and placement of an interbody graft between L5 and S1. Both minimally invasive and open surgical techniques are used to treat anterolisthesis ...

    These cannot be determined by plain films, as the x-ray passes through the soft tissue. A study by Giles et al., stated that sixteen of the thirty patients (53%) had retrolisthesis of L5 on S1 ranging from 2–9 mm; these patients had either intervertebral disc bulging or protrusion on CT examination ranging from 3–7 mm into the spinal canal.

  4. Lumbar spinal stenosis - Wikipedia

    en.wikipedia.org/wiki/Lumbar_spinal_stenosis

    MRI of a lumbar spinal stenosis L4-L5. L4-L5 antherolisthesis of grade I. Hypertrophy of interspinous ligaments in relation to Baastrup's disease. 67 years old man. MRI is the preferred method of diagnosing and evaluating spinal stenosis of all areas of the spine, including cervical, thoracic, and lumbar.

  5. Congenital vertebral anomaly - Wikipedia

    en.wikipedia.org/wiki/Congenital_vertebral_anomaly

    In sacralization, the L5-S1 intervertebral disc may be thin and narrow. This abnormality is found by X-ray. [citation needed] Sacralization of L6 means L6 attaches to S1 via a rudimentary joint. This L6-S1 joint creates additional motion, increasing the potential for motion-related stress and lower back pain/conditions.

  6. Lumbar vertebrae - Wikipedia

    en.wikipedia.org/wiki/Lumbar_vertebrae

    In human anatomy, the five vertebrae are between the rib cage and the pelvis.They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (since it is only found in the cervical region) and by the absence of facets on the sides of the body (as found only in the thoracic region).

  7. 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.

  8. Spondylolysis - Wikipedia

    en.wikipedia.org/wiki/Spondylolysis

    This tracer decays and emits radioactive energy which can be detected by a special camera. The camera produces a black and white image where areas shown as dark black indicate bone damage of some kind. If there is a black spot in the lumbar vertebrae (e.g. L5) this indicates damage and potentially spondylolysis.

  9. Disc herniation - Wikipedia

    en.wikipedia.org/wiki/Disc_herniation

    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.
