What does ligamentum flavum redundancy mean?
What is ligamentum flavum redundancy? It means that the Ligamentum Flavum is overgrown or split in two. This is the result of segmental instability usually from a degenerating disc between adjacent vertebrae.
What causes ossification of ligamentum flavum?
Ossification of the ligamentum flavum is an acquired degenerative disease that was first described by Polgar36 in 1920 on lateral radiograms. It occurs through endochondral ossification of hypertrophied fibrous tissue within the ligaments.
What is calcified ligamentum flavum?
Calcification of the ligamentum flavum (CLF) is a rare disease mainly occurring in the cervical spine (Miyasaka et al. 1983). CLF results in posterior spinal cord compression, which may cause myelopathy and successive neurological deficits. It mostly occurs in the Asian population (Ahn et al. 2014).
What is Ligamenta Flava?
The ligamenta flavum is a short but thick ligament that connects the laminae of adjacent vertebrae from C2 to S1 and is considered a medial ward continuation of the fact joint . This high percentage of elastin fibers provides the ligament it’s yellow color and flexible nature.
What is unusual about the ligamentum flavum?
Ligamentum flavum literally means “yellow ligament,” and is so known because it has a yellow coloring due to the amount of elastin (a springy type of collagen). The ligament can become a substantial contributor to spinal stenosis, and is usually removed during a lumbar decompression surgery.
What is Opll syndrome?
Spine Disorders Ossification of the posterior longitudinal ligament (OPLL) is a condition in which a flexible structure known as the posterior longitudinal ligament becomes thicker and less flexible. The posterior longitudinal ligament connects and stabilizes the bones of the spinal column.
Where is the Ligamenta Flava located?
The ligamenta flava (singular, ligamentum flavum) are paired ligaments (left and right) that run between the laminae of adjacent vertebrae (see Fig. 5-16). They are found throughout the spine beginning with C1-2 superiorly and ending with L5-S1 inferiorly.
What is Ligamenta flava hypertrophy?
Ligamentum flavum hypertrophy refers to abnormal thickening of the ligamentum flavum. If severe, it can be associated with spinal canal stenosis.
