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. [citation needed]
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 becomes taut when the spine is fully flexed. [4] The supraspinous ligament, along with the posterior longitudinal ligament, interspinous ligaments and ligamentum flavum, help to limit hyperflexion of the vertebral column.
They extend from the root to the apex of each spinous process. They meet the ligamenta flava anteriorly, [4] [better source needed] and blend with the supraspinous ligament [3] posteriorly at the apexes of the spinal processes. The function of the interspinous ligaments is to limit ventral flexion of the spine and sliding movement of the ...
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 ...
A spinal needle is inserted between the lumbar vertebrae L3/L4, L4/L5 [10] or L5/S1 [10] and pushed in until there is a "give" as it enters the lumbar cistern wherein the ligamentum flavum is housed. The needle is again pushed until there is a second 'give' that indicates the needle is now past the dura mater .
