Each ligamentum flavum connects the laminae of two adjacent vertebrae. [2] [3] They attach to the anterior portion of the upper lamina above, and the posterior portion of the lower lamina below. [1] They begin with the junction of the axis and third cervical vertebra, continuing down to the junction of the 5th lumbar vertebra and the sacrum. [2 ...
From a clinical standpoint, denticulate ligaments do not play a significant role in lumbar spinal stenosis when compared to issues such as disc herniations, facet hypertrophy, shape of spinal canal, size of spinal canal, ligamentum flavum hypertrophy, or degenerative joint disease resulting in bony osteophyte formation.

This definition reflects the current hypotheses for the pathophysiology of NC, which is thought to be related to the compression of lumbosacral nerve roots by surrounding structures, such as hypertrophied facet joints or ligamentum flavum, bone spurs, scar tissue, and bulging or herniated discs.
The supraspinous ligament connects the tips of the spinous processes from the seventh cervical vertebra to the sacrum. [1] Superior to the 7th cervical vertebra, the supraspinous ligament is continuous with the nuchal ligament.
In older patients, CCS most often occurs after acute hyperextension injury in an individual with long-standing cervical spondylosis.A slow, chronic cause in this age group is when the cord gets caught and squeezed between a posterior intervertebral disc herniation against the anterior cord and/or with posterior pressure on the cord from hypertrophy of the ligamentum flavum (Lhermitte's sign ...
The vertebral canal is enclosed anteriorly by the vertebral bodies, intervertebral discs, and the posterior longitudinal ligament; it is enclosed posteriorly by the vertebral laminae and the ligamenta flava; laterally, it is incompletely enclosed by the pedicles with the interval between two adjacent pedicles on either side creating an intervertebral foramen (allowing the passage of the spinal ...
The anterior longitudinal ligament extends superoinferiorly between the basiocciput of the skull and the anterior tubercle of the atlas (cervical certebra C1) superiorly, and the superior part of the sacrum inferiorly; [1] inferiorly, it ends at the sacral promontory. [2]
The interspinous ligaments (interspinal ligaments) are thin, membranous ligaments that connect adjoining spinous processes of the vertebra in the spine. [1] [2] They take the form of relatively weak sheets of fibrous tissue and are well developed only in the lumbar region.
