anterior longitudinal ligament (anatomy)

Last reviewed 01/2018

The anterior longitudinal ligament is a thick band of fibrous tissue that runs along the anterior surfaces of vertebral bodies. It extends from the anterior tubercle of the atlas bone inferiorly down the full length of the spinal column to fuse with the upper, pelvic surface of the sacrum. On route, it firms blends with the periosteum of successive vertebrae. It is less firmly attached to intervertebral discs.

The anterior longitudinal ligament is a guard against hyperextension of the spine. Rupture may occur if there is sudden forceful hyperextension e.g. 'whiplash' injuries.
