What is a herniation of the nucleus pulposus?
Herniated nucleus pulposus is a condition in which part or all of the soft, gelatinous central portion of an intervertebral disk is forced through a weakened part of the disk, resulting in back pain and nerve root irritation.
What causes herniation of nucleus pulposus?
The most common cause of a cervical herniated nucleus pulposus is gradual degeneration of the disc, attenuation (weakening) of the posterior annulus fibrosis, and subsequent protrusion of the nucleus pulposus into the spinal canal causing compression of the nerve root.
Is herniated nucleus pulposus serious?
Herniated Nucleus Pulposus Symptoms While a herniated nucleus pulposus is asymptomatic, a protruding nucleus can compress nearby nerves or the spinal cord, sometimes leading to serious nerve damage and should be treated immediately.
What is the use of nucleus pulposus?
The nucleus pulposus is located in the spine, between two vertebrae, where it plays a major role in providing the spine with shock absorption during movement. It prevents bone to bone contact, reducing the possibility of injuries and pain.
How long does herniated nucleus pulposus take to heal?
The average amount of time it takes for a herniated disk to heal is four to six weeks, but it can get better within a few days depending on how severe the herniation was and where it occurred. The biggest factor in healing a herniated disk is time, because most often it will resolve on its own.
Does nucleus pulposus grow back?
To regenerate nucleus pulposus tissue, the cells must produce an appropriate proteoglycan-rich matrix, as this is essential for the functioning of the intervertebral disc. There are some clinical trials and reports of attempts to regenerate nucleus pulposus utilising either autologous or allogenic cells.
Why does nucleus pulposus herniate Posterolaterally?
When degenerative changes (with or without trauma) result in protrusion or rupture of the nucleus through the annulus fibrosus in the lumbosacral or cervical area, the nucleus is displaced posterolaterally or posteriorly into the extradural space.
What type of tissue is the nucleus pulposus?
Nucleus pulposus is a tissue rich in small molecule elastic mucin, which is mostly based on the degeneration of bone joint and fibrous ring.
What is the nucleus pulposus function?
What is a posterior disc herniation?
A posterior disc herniation is damage that occurs in the lower lumbar area of the spine, which is the lower portion of the back. The spine is made up of vertebrae, or bones, that are cushioned by discs. One of these discs may become herniated when a portion of its soft center bulges outward.
What is a spinal bulging disc?
A bulging disc in the neck can occur when a spinal disc slips out of place. This can lead to a herniated disc, wherein damage causes the inner substance of the disc to leak out. Both conditions can cause pain in the neck. Physical therapy and exercises can help treat a bulging disc in the neck.
What is the prognosis for a herniated disc?
Most back and leg pain will get better gradually – usually within six weeks – by taking simple measures. In fact, most people with herniated disks respond to conservative treatment within six weeks and are able to return to their normal activities. Some will continue to have back pain even after treatment.
What is a herniated disc which abuts the cord?
A herniated disc abutting the spinal cord is a diagnostic conclusion mostly seen on spinal MRI reports for back and neck pain sufferers. Alternatively, the same conclusion may be stated in any of the following language: herniated disc touching the spinal cord, herniated disc effacing the spinal cord or herniated disc encroaching upon the spinal cord.
