Ligamentum longitudinale posterius
Read moreAnatomical Relations
The posterior longitudinal ligament descends within the vertebral canal along the posterior aspect of the vertebral bodies and intervertebral discs.
Function
This ligament prevents hyperflexion of the vertebral column and reinforces the posterior aspect of the sacrum.
Structure
Similar to the anterior longitudinal ligament, the superficial layer of the posterior longitudinal ligament has the longest fibers that can extend over several vertebrae while the deep layer only extends between adjacent vertebrae. The fibers have particularly strong attachments to the anulus fibrosus of the intervertebral discs.
