Each ligamentum flavum connects the laminae of two adjacent vertebrae. [2] [3] They attach to the anterior portion of the upper lamina above, and the posterior portion of the lower lamina below. [1] They begin with the junction of the axis and third cervical vertebra, continuing down to the junction of the 5th lumbar vertebra and the sacrum. [2 ...
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]
It has been suggested that some animals, such as the orangutan and Indian elephant, lack a ligamentum teres. [7] [8] However, the presence of a ligamentum teres, albeit with a morphology different from the human version, has been found upon dissection in both these animals. In the orangutan, it is believed to play a significant role in ...
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.
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 ]
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 ...
There are numerous ligaments extending the length of the column, which include the anterior and posterior longitudinal ligaments at the front and back of the vertebral bodies, the ligamentum flavum in deep to the laminae, the interspinous and supraspinous ligaments between spinous processes, and the intertransverse ligaments between the ...
As a needle is advanced through the ligamentum flavum, to the epidural space, with constant pressure applied to the piston of a syringe, loss of resistance occurs once the needle enters the epidural space due to the change in pressure.
