This sounds like the soft tissue id pouting pressure on nerves parsing between the vertebrae.
dont know the answer to the question dont know the answer to the question
They can be the contributors to the stenosis.
The individual vertebrae are linked with the help of connecting tissues known as ligamentum flavum, When there is noticeable swelling due to inflammatory or degenerative changes, it is known as Ligamentum flavum thickening. A spinal MRI scan will be able to detect the swelling.
Ligamentum flavum is placed in the vertebral canal anterior to the spines of vertebrae and laminae of the vertebrae. Thickening of this ligament is common cause of spinal stenosis. Facet on the transverse process in enlarged in a given patient.
ligamentum flavum hypertrophy is a degenerative condition of the spine which most commonly occurs in the elderly where the tendons holding one vertebra to another thicken, decreasing the amount of room available for the spinal cord and the nerves that come off it. It may be associated with inflammation (arthritis) or osteoporosis. It is frequently treated surgically, and it can recur. This one seems a bit complex to answer easily, So if you follow the related link (Hypertrophy of Ligamentum Flavum in Lumbar Spinal Stenosis) you will find more information.
Hypertrophy of the ligaments in the vertebral canal of the spinal column can narrow the canal (stenosis) to the point that the spinal cord and/or nerve roots running through the canal are compressed. When the posterior longitudinal ligament in front and ligamentum flavum behind the spinal cord hypertrophy the cord is almost "circumferentially" surrounded and compressed.Hypertrophy of the ligamentum flavum laterally near the facet joint can also contribute to foraminal narrowing (stenosis) with potential nerve compression (pinching).Source(s):uscneurosurgerysearch.yahoo.com
Moderate facet arthropathy is Arthritis in the facet joints. Most people that have this will complain of pain in their lower back. Facet joints are joint structures that connect the vertebrae to each other.
what is bilateral facet hypertrophy at L5-S1
The discs in your back are separated by what are called Facets, one on left. one on the right that are placed up and down (bilatteral. ) Screw it, basically what it means is the the "facets" are breaking down and can cause two discs in you back to be touching each other. But if it's mild than try to do some strengthing to your back muscle and maybe that will help the arthropath and hypertrophy to help you back ligamnts and slow down the process of any degenerative facets.
