Description[edit | edit source]
Forming the anterior wall of the vertebral canal, this strong ligament spans from the body of the Axis (C2) to the posterior surface of the sacrum. Like its anterior counterpart the Anterior longitudinal ligament, its deep fibres are intersegmental while the more superficial fibres can span up to four vertebral levels.
In the cervical and thoracic regions it has a uniform width over the bodies and discs, but in the lumbar region the ligament is widest at the levels of the intervertebral discs where it is firmly anchored to the Annulus fibrosus, cartilage of the Vertebral end plates, and the margins of the vertebrae. Its cranial counterpart is the Tectorial membrane.
