ligamentum flavum การใช้

The " ligamentum flavum " and " dura mater " are not as thick in infants and children as they are in adults.
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 middle notch becomes narrowed by facet joint hypertrophy, ligamentum flavum infolding and shoulder osteophytes with further compromise due to the tethering of the nerve to the ascending facet or disc.
The pathophysiology is thought to be ischemia of the lumbosacral nerve roots secondary to compression from surrounding structures, hypertrophied facets, ligamentum flavum, bone spurs, scar tissue, and bulging or herniated discs.
The iliac crest is a commonly used anatomical landmark for lumbar epidural injections, as this level roughly corresponds with the fourth lumbar vertebra, which is usually well below the ligamentum flavum and the epidural space.
