What is the role of the posterior longitudinal ligament?
The functions of the posterior longitudinal ligament are to prevent hyperflexion and to support the posterior aspects of the anterior vertebral column.Click to see full answer. Similarly, what movement does the posterior longitudinal ligament limit? Primary Spinal Ligaments Include: Ligament Spinal Region Limits… Anterior Longitudinal Axis – Sacrum Extension & reinforces front of annulus fibrosis…

Similarly, what movement does the posterior longitudinal ligament limit? Primary Spinal Ligaments Include: Ligament Spinal Region Limits… Anterior Longitudinal Axis – Sacrum Extension & reinforces front of annulus fibrosis Posterior Longitudinal Axis – Sacrum Flexion & reinforces back of annulus fibrosis Ligamentum Flavum Axis – Sacrum Flexion Supraspinous Thoracic & Lumbar Flexion Subsequently, question is, what is thickening of the posterior longitudinal ligament? This is a thin ligament which lies behind the vertebral bodies and discs. Degenerative changes in the spine may cause this structure to become thickened, (hypertrophy of the Posterior longitudinal ligament (PLL)) or even calcified (Ossification of the posterior longitudinal ligament (OPLL)). Thereof, where does the posterior longitudinal ligament attach? The posterior longitudinal ligament (PLL) is a long and important ligament located immediately posterior to the vertebral bodies (to which it attaches loosely) and intervertebral discs (to which it is firmly attached). It extends from the back of the sacrum inferiorly and gradually broadens as it ascends.What causes calcification of the posterior longitudinal ligament?OPLL is a multifactorial condition caused by ectopic hyperostosis and calcification of the posterior longitudinal ligament. Familial inheritance and genetic factors have been implicated in the etiology of OPLL. The cervical spine is most commonly affected followed by the thoracic spine.
