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.
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 may be the experience that causes the patient to seek medical diagnosis). However ...
The ligamentum flavum (yellow ligament), an important structural component intimately adjacent to the posterior portion of the dural sac (nerve sac) can become thickened and cause stenosis. The articular facets, also in the posterior portion of the bony spine can become thickened and enlarged, causing stenosis.
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 ...
The supraspinous ligament, along with the posterior longitudinal ligament, interspinous ligaments and ligamentum flavum, help to limit hyperflexion of the vertebral column. Clinical significance [ edit ]
Weight loss, to relieve symptoms and slow the progression of the stenosis; Physical therapy to support self-care. [37] Also may give instructions on stretching and strength exercises that may lead to a decrease in pain and other symptoms. Lumbar epidural steroid or anesthetic injections have low quality evidence to support their use. [36] [38]
The ligamentum flavum did not appear to alter the dynamic alterations in the dimensions of the spinal cord. Even after the intervertebral disc was removed, the ligamentum flavum did not appear to be a factor in the change in the dimensions of the spinal canal. [6] By understanding the magnitude of the role that ligamentum flavum hypertrophy ...
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.
