Posterior longitudinal ligament

from Wikipedia, the free encyclopedia
Ossification of the posterior longitudinal ligament of the cervical spine in computed tomography , sagittal reconstruction. This can lead to a narrowing of the spinal canal.

The ligamentum longitudinal posterius ("posterior longitudinal ligament"), known in animals as the ligamentum longitudinal posterior ("posterior longitudinal ligament"), is a longitudinal ligament of the spine . It consists of tight, collagenous connective tissue and connects the individual vertebral bodies to one another at the back of the vertebrae and thus lies within the vertebral canal . It is only loosely connected to the vertebral bodies, but firmly to the intervertebral discs . It starts at the second cervical vertebra and extends to the sacrum . From the second cervical vertebra it goes headward into the tectoria membrane , which extends to the occiput .

The ligamentum longitudinal posterius is one of the long spinal ligaments along with the ligamentum longitudinal anterius , ligamentum supraspinale and ligamentum nuchae . According to another classification, it belongs to the ligamentum longitudinal anterius to the vertebral body ligaments , which are opposed to the rest of the so-called vertebral arch ligaments .
