[1] A disc protrusion is a medical condition that can occur in some vertebrates, including humans, in which the outermost layers of the anulus fibrosus of the intervertebral discs of the spine are intact but bulge when one or more of the discs are under pressure. Many disk abnormalities seen on MRI that are loosely referred to as "herniation" are
Lumbar spinal stenosis may be overlooked, especially when it is associated with disc protrusion or herniation. Removal of a disc, while not addressing the underlying presence of stenosis, can lead to disappointing results. [11] Occasionally operating on the wrong level occurs, as does failure to recognize an extruded or sequestered disc fragment.
Schmorl's nodes are fairly common, especially with minor degeneration of the aging spine, but they are also seen in younger spines. Schmorl's nodes often cause no symptoms, but may simply reflect that "wear and tear" of the spine has occurred over time; they may also reflect that bone strength was at one time somewhat compromised, perhaps due to a vitamin D deficiency although this has yet to ...
This classification describes how far away from mid-line a disc protrusion is using a grade of A, B, or C. [7] Grade A describes a herniation at midline. Grade C herniations are the most lateral and protrude into the intervertebral foramen (through which spinal nerves travel).
There is a disc between each of the vertebrae in the spine. A healthy, well-hydrated disc will contain a great deal of water in its center, known as the nucleus pulposus, which provides cushioning and flexibility for the spine. Much of the mechanical stress that is caused by everyday movements is transferred to the discs within the spine and ...
Disc herniation is normally a further development of a previously existing disc protrusion, in which the outermost layers of the annulus fibrosus are still intact, but can bulge when the disc is under pressure. In contrast to a herniation, none of the central portion escapes beyond the outer layers.
Use the Disk Cleanup function on Windows. Windows has a built-in feature that helps you free up disk space; it’s called Disk Cleanup. Just click the Start button and then search for it by name.
Lumbar disc disease is the drying out of the spongy interior matrix of an intervertebral disc in the spine. Many physicians and patients use the term lumbar disc disease to encompass several different causes of back pain or sciatica. In this article, the term is used to describe a lumbar herniated disc.
