Anterior Longitudinal Ligament

The anterior longitudinal ligament is a crucial anatomical structure in the human body, specifically within the vertebral column. It is one of the four main ligaments that provide stability and support to the spine.

Anatomy

The anterior longitudinal ligament runs vertically along the anterior surface of the vertebral bodies and intervertebral discs. It extends from the base of the skull, at the level of the occipital bone, to the sacrum. The ligament is broader at the top and bottom of the vertebral bodies and narrower at the intervertebral discs.

Function

The primary function of the anterior longitudinal ligament is to limit the extension and rotation of the vertebral column, thereby preventing hyperextension injuries. It also helps to maintain the alignment of the vertebral bodies and contributes to the stability of the spine.

Clinical Significance

Injuries to the anterior longitudinal ligament can occur due to trauma, such as a car accident or fall, or due to degenerative conditions like ankylosing spondylitis. Damage to this ligament can lead to instability of the spine, chronic back pain, and in severe cases, neurological deficits.
