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 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.
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.
ligamentum arteriosum: extra-hepatic portion of the fetal left umbilical vein: ligamentum teres hepatis (the "round ligament of the liver"). intra-hepatic portion of the fetal left umbilical vein (the ductus venosus) ligamentum venosum: distal portions of the fetal left and right umbilical arteries: medial umbilical ligaments
In this procedure, the ligamentum flavum is first removed, followed by the removal of the superior facet osteophyte in the spinal canal, and then the decompression of the spinal nerve root. [ 5 ] [ 11 ] Another surgical method of decompression is the Fenestration method, which involves creating a small window in the spinal canal and then ...
