Spinal stenosis can be secondary to the causes of degenerative, congenital, and acquired etiologies. Degenerative causes, such as degenerative disc disease or ligamentum flavum (LF) hypertrophy, are the most common and increase in frequency with advancing age. Anatomic variations of spinal vertebrae ...
Damage from the rubbing causes the formation of bony growths called bone spurs. Bone spurs may push into the spinal canal or forament space. Tissues surrounding the spinal cord, such as the ligamentum flavum and posterior longitudinal ...
bony protrusions (spondylophytes) form, which then narrow both the spinal canal and the nerve exit openings. Another cause is an abnormal thickening of the ligaments between the vertebrae that stabilize the spine (ligamentum flavum). All degenerative changes result in the space for the nerves run...
The canal components that contribute to acquired stenosis include the facets (hypertrophy, arthropathy), ligamentum flavum (hypertrophy), posterior longitudinal ligament (ossification of posterior longitudinal ligament [OPLL]), vertebral body (bone spurs), intervertebral disk, and epidural fat. Congenital ...
The dimensions of the bony canal are reduced by the posterior longitudinal ligament lying on the posterior aspect of the vertebral bodies and posterolaterally by the ligamentum flavum (see Figure 6.1). The size of the vertebral canal varies between individual spines and among segments of the same...
腰椎管狭窄(LumbarSpinalStenosis)-双语学习 Lumbar stenosis is narrowing of the spinal canal and narrowing of the intervertebral foramen, which is the nerve root canal. Hypertrophy of the facet joints, hypertrophy of the ligamentum flavum, disc degeneration, or arthritis are all examples of conditions...
the ligamentum flavum—the ligaments of the spine—can grow, which can impact the spinal column and cause either partial or severe spinal stenosis. When you age, the fluid-filled cushions between your spinal disks can begin to dry and shrink; they may also herniate (protrude or rupture abnorm...
The number of the patients of spinal stenosis is increasing in the aging society like Japan because the major reason for the stenosis is the degeneration of the spinal components including the intervertebral disc, facet, and ligamentum flavum. The development of the disease-concept is historically ...
Lumbar stenosis is narrowing of the spinal canal and narrowing of the intervertebral foramen, which is the nerve root canal. Hypertrophy of the facet joints, hypertrophy of the ligamentum flavum, disc degeneration, or arthritis are all examples of conditions which constrict the nerve root canals, ...
Spinal canal stenosis Neural structures of the spine can become compressed by the bony and ligamentous tissues of the spinal canal. Categorization by means of localization is effective in lateral (foramen, lateral recess) and central stenosis of the spin
