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. Hypertrophy can cause spinal stenosis.
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.

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 ...
MRI of a lumbar spinal stenosis L4-L5. L4-L5 antherolisthesis of grade I. Hypertrophy of interspinous ligaments in relation to Baastrup's disease. 67 years old man. MRI is the preferred method of diagnosing and evaluating spinal stenosis of all areas of the spine, including cervical, thoracic, and lumbar.
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 ligamentum flavum and dura mater are not as thick in infants and children as they are in adults. Therefore, it is difficult to assess when the needle passes through them into the subarachnoid space because the characteristic "pop" or "give" may be subtle or nonexistent in the pediatric lumbar puncture.
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.
