What is the posterior longitudinal ligament?
The posterior longitudinal ligament runs the entire length of the spine from the neck to the end of the spine and stabilizes the spinal column bones. Ossification of the posterior longitudinal ligament most commonly occurs in the cervical spine (neck).
Which ligament is the upward continuation of Membrana Tectoria?
the posterior longitudinal ligament
The axis is connected to the occipital bone by membrana tectoria, which is the upward continuation of the posterior longitudinal ligament, the alar ligaments between the lateral aspect of the apex of the dens and medial side of the occipital condyles, the apical ligament of the dens between the apex of the dens and the …
How is OPLL treated?
Ossification of the posterior longitudinal ligament (OPLL) is a rare but potentially devastating cause of degenerative cervical myelopathy (DCM). Decompressive surgery is the standard of care for OPLL and can be achieved through anterior, posterior, or combined approaches to the cervical spine.
Where does the posterior longitudinal ligament attach?
The posterior longitudinal ligament runs in the spinal canal attaching to the vertebral bodies and vertebral discs and tightens with cervical flexion.
What is Membrana Tectoria?
The membrana tectoria is situated within the vertebral canal. It is a broad, strong bands which covers the odontoid process and its ligaments, and appears to be a prolongation upward of the posterior longitudinal ligament of the vertebral column.
What is the posterior longitudinal ligament innervated by?
the sinuvertebral nerve
The posterior longitudinal ligament (PLL) is richly innervated by nociceptive fibers from the ascending branch of the sinuvertebral nerve ( Figure 3). These nerves also provide sensory innervation of the adjacent outer layers of the annulus fibrosus [34]. …
What nerve innervates the posterior longitudinal ligament?
Where is the anterior longitudinal ligament?
vertebral body
The anterior longitudinal ligament lies on the ventral surface of the vertebral body through the entire length of the vertebral column; it also sweeps around the lateral aspect of the vertebral bodies (Hayashi et al., 1977).
Which ligament forms the posterior margin of the vertebral canal?
posterior longitudinal ligament (PLL)
Anatomy. The posterior longitudinal ligament (PLL) (Fig. 2-2) is a band of longitudinal fibers that runs within the vertebral canal along the posterior aspect of the vertebral bodies. Rostrally, the PLL is continuous with the tectorial membrane, and in the upper lumbar region the PLL takes on a caudal direction.
What nerve innervates the anterior longitudinal ligament?
rami communicantes
The anterior longitudinal ligament is innervated by recurrent branches of rami communicantes.
