The marked elasticity of the ligamenta flava serves to preserve upright posture, and to assist the vertebral column in resuming it after flexion. The elastin, fairly unique to the ligamenta flava among other ligaments, [2] prevents buckling of the ligament into the spinal canal during extension, which would cause spinal cord compression.
The posterior atlantoaxial ligament is a broad, thin membrane attached, above, to the lower border of the posterior arch of the atlas; below, to the upper edges of the laminæ of the axis. It supplies the place of the ligamenta flava , and is in relation, behind, with the obliqui capitis inferiores .
A laminotomy is an orthopaedic neurosurgical procedure that removes part of the lamina of a vertebral arch in order to relieve pressure in the vertebral canal. [1] A laminotomy is less invasive than conventional vertebral column surgery techniques, such as laminectomy because it leaves more ligaments and muscles attached to the spinous process intact and it requires removing less bone from the ...
Inferiorly, it becomes continuous with the anterior sacrococcygeal ligament. [3] Superiorly, between the skull and atlas, the ligament is continuous laterally with the anterior atlantooccipital membrane. [4] The ligament is thick and slightly more narrow over the vertebral bodies and thinner but slightly wider over the intervertebral discs. [5]
Lesions to the supraspinous ligament may result in palpable thickening. [5] Ultrasound is effective for detecting lesions. [5] [6] A strain injury can also damage the supraspinous ligament. [7] The supraspinous ligament creates resistance during midline epidural anaesthetics when the needle is being inserted.
The iliolumbar ligament strengthens the lumbosacral joint assisted by the lateral lumbosacral ligament, and, like all other vertebral joints, by the posterior and anterior longitudinal ligaments, the ligamenta flava, and the interspinous and supraspinous ligaments. [4] It reduces the range of movement of the lumbosacral joint. [6]
The nuchal ligament is unusual in being a ligament with an elastic component, allowing for stretch. [5] Structurally, the nuchal ligament is formed with the association of both elastin proteins as well as type III collagen (45%). The collagen fibrils share a consistent size as well as helical pattern which gives the ligament its tensile ...
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 ...
