Spinal cord compression (summary)

This is a basic article for medical students and other non-radiologists Spinal cord compression is a surgical emergency and if unrecognised or untreated, can result in irreversible neurological damage and disability. If the spinal roots below the conus medullaris are involved, it is termed caud...

Anterior longitudinal ligament

The anterior longitudinal ligament (ALL) runs along the anterior surface of the vertebral bodies (firmly united to the periosteum) and intervertebral discs (attaching to the anterior annulus). It ascends from the anterosuperior portion of the sacrum inferiorly to the become the anterior atlanto-...

Anterior atlanto-occipital membrane

The anterior atlanto-occipital membrane is a thin membrane that joins the upper border of the anterior arch of the atlas (C1) to the anterior inferior surface of the foramen magnum. It is a continuation of the anterior longitudinal ligament above the C1 level. It is immediately posterior to the ...

Apical ligament

The apical ligament is a small ligament that joins the apex (tip) of the dens of C2 to the anterior margin (basion) of the foramen magnum. It is the weak, fibrous remnant of the notochord and does not contribute significantly to stability. The more posterior alar and cruciate ligaments are stro...

Alar ligament

The alar ligaments join the lateral margins of the sloping upper posterior margin of the dens of C2 to the lateral margins of the foramen magnum (adjacent to the occipital condyles) and lie on either side of the apical ligament. They may be oblique or vertical and are thickest at the occipital a...

Cruciate ligament of the atlas

The cruciate ligament of the atlas (also known as the cruciform ligament) is an important ligamentous complex that holds the posterior dens of C2 in articulation at the median atlantoaxial joint. It lies behind a large synovial bursa (surrounded by loose fibrous capsule) and consists of two band...

Posterior longitudinal ligament

The posterior longitudinal ligament (PLL) is a long and important ligament located immediately posterior to the vertebral bodies (to which it attaches loosely) and intervertebral discs (to which it is firmly attached). It extends from the back of the sacrum inferiorly and gradually broadens as ...

Tectorial membrane of the spine

The tectorial membrane is the thin superior continuation of the posterior longitudinal ligament from the body of the axis. It joins the axis body to the clivus on the anterior half of the foramen magnum, and ascends as high as the spheno-occipital synchondrosis and laterally extends to the hypog...

Posterior atlanto-occipital membrane

The posterior atlanto-occipital membrane attaches the anterosuperior border of the posterior arch of the atlas (C1) to the posterior margin of the foramen magnum. It lies immediately posterior to the spinal theca and is continuous inferiorly with the ligamentum flavum (sometimes referred to at C...

Interspinous ligament

The interspinous ligaments join the spinous processes along their adjacent borders. They are composed of relatively weak fibrous tissue that fuses with the stronger, supraspinous ligaments.

Supraspinous ligament

The supraspinous ligament runs along the tips of adjacent spinous processes and is particularly thick in the cervicothoracic region. Above the level C7 spinous process the ligament no longer directly attaches to the spinous process but rather continues as the nuchal ligament up to its attachment...
