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]
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 vertebrae. [5] The ligaments are narrow and elongated in the thoracic ...
Superior to the 7th cervical vertebra, the supraspinous ligament is continuous with the nuchal ligament. [2]: 45 It is thicker and broader in the lumbar region than in the thoracic region, and intimately blended with the neighboring fascia in both these regions. [3]
Spinal stenosis is a narrowing of the canal which can occur in any region of the spine and can be caused by a number of factors. It may result in cervical myelopathy [4] if the narrowed canal impinges on the spinal cord itself. Spinal canal endoscopy can be used to investigate the epidural space, and is an important spinal diagnostic technique ...
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 nuchal ligament extends from the external occipital protuberance on the skull and median nuchal line to the spinous process of the seventh cervical vertebra in the lower part of the neck. [ 1 ] From the anterior border of the nuchal ligament, a fibrous lamina is given off.
Transforaminal ligaments are inconstant ligaments that extend through an intervertebral foramen.They are thought to protect the adjacent spinal nerve and vessels. The ligaments are not widely known and were once considered anomalous; there are no widely accepted criteria for their identification and classification.
