Severe narrowing of the lateral portion of the canal is called lateral recess stenosis. 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.
Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in ... This is a very effective study in cases of lateral recess stenosis ...
Lumbar spinal stenosis is formally defined as a decline in diameter length of either the neural foramina, lateral recess, or spinal canal. [1] Stenosis is classified as a decaying disease because it causes the canal to gradually become more and more narrow which can cause pain or loss of function. [1]
The lateral recess or lateral recess of fourth ventricle, is a projection of the fourth ventricle which extends to the lateral border of the brainstem at the pontomedullary junction. [1] [2] At this point the fourth ventricle is at its widest. [1] The lateral recess on each side opens into a lateral aperture (foramen of Luschka) that opens into ...
The facet joints are formed by the superior and inferior processes of each vertebra. The first cervical vertebra has an inferior articulating surface but, as it does not restrict lateral or posterior translation, is not always considered a proper zygoma [9] (zygoma is Greek for "yoke", i.e. something that restrains movement).
The lumbar cistern is part of the subarachnoid space.It is the space within the thecal sac which extends from below the end of the spinal cord (the conus medularis), typically at the level of the first to second lumbar vertebrae down to tapering of the dura at the level of the second sacral vertebra.
A drop in estradiol and progesterone levels after menopause could increase cartilage aging and degeneration, leading to osteoarthritis, a study in mice suggests.
The cerebellopontine angle (CPA) (Latin: angulus cerebellopontinus) is located between the cerebellum and the pons. [1] The cerebellopontine angle is the site of the cerebellopontine angle cistern.
