The posterior longitudinal ligament contains a higher density of nociceptors than many ligaments, so can cause back pain. [1] It may ossify, particularly around cervical vertebrae. [1] The posterior longitudinal ligament has a high density of vasomotor fibres, allowing for increased blood flow to respond to damage to the ligament. [1]
Although joints can occur singly, they most frequently appear as joint sets and systems. A joint set is a family of parallel, evenly spaced joints that can be identified through mapping and analysis of their orientations, spacing, and physical properties. A joint system consists of two or more intersecting joint sets. [1] [2] [3]
The consequence of a broken ligament can be instability of the joint. Not all broken ligaments need surgery, but, if surgery is needed to stabilise the joint, the broken ligament can be repaired. Scar tissue may prevent this. If it is not possible to fix the broken ligament, other procedures such as the Brunelli procedure can correct the ...
The cruciate ligament of the atlas (cruciform ligament) is a cross-shaped (thus the name) ligament in the neck forming part of the atlanto-axial joint. It consists of the transverse ligament of atlas, a superior longitudinal band, and an inferior longitudinal band. The cruciate ligament of the atlas prevents abnormal movement of the atlanto ...
Anterior longitudinal ligament (ligamentum longitudinale anterius), which runs down the anterior surface of the spine; Posterior longitudinal ligament (ligamentum longitudinale posterius), which is situated within the vertebral canal, and extends along the posterior surfaces of the bodies of the vertebrae
The anterior longitudinal ligament is a ligament that extends across the anterior/ventral aspect of the vertebral bodies and intervertebral discs the spine. It may be partially cut to treat certain abnormal curvatures in the vertebral column , such as kyphosis .
In joint systems where relatively long joints cut across the outcrop, the throughgoing joints act as master joints and the short joints that occur in between are cross joints. Poisson effect is the creation of vertical contraction fractures that are a result of the relief of overburden over a formation.
The ligamenta flava (sg.: ligamentum flavum, Latin for yellow ligament) are a series of ligaments that connect the ventral parts of the laminae of adjacent vertebrae.They help to preserve upright posture, preventing hyperflexion, and ensuring that the vertebral column straightens after flexion.
