Bulging and Herniated Discs Explained "A bulging disc is like letting air out of a car tire. The disc sags and looks like it is bulging outward. With a herniated disc, the outer covering of the disc has a hole or tear. This causes the nucleus pulposus (jelly-like center of the disc) to leak into the spinal canal."
Overview. 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.
The nucleus pulposus is the soft, gelatinous central portion of the intervertebral disk that moves within the disk with changes in posture. In the normal disk, the nucleus pulposus moves anteriorly with lumbar extension and frequently communicates with the epidural space and surrounding structures.
Other intervertebral disc displacement, thoracolumbar region The 2022 edition of ICD-10-CM M51. 25 became effective on October 1, 2021.
The symptoms due to herniated nucleus pulposus (HNP) can ultimately be attributed to the significant inflammatory response it generates inside the spinal canal.
A herniated nucleus pulposus occurs when the soft nucleus of a disc begins to leak out from within the the annular fibrosus, the disc's hard outer casing . This often occurs as a result of natural aging, during which discs regularly lose water content and become susceptible to dehydration and begin to degrade.
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.
Diagnosis of Herniated Nucleus Pulposus MRI or CT can identify the cause and precise level of the lesion. Rarely (ie, when MRI is contraindicated and CT is inconclusive), CT myelography is necessary. Electrodiagnostic testing may help identify the involved root.
Complications associated with nucleus pulposus herniation can result from the compression effect on the nerve root in severe cases resulting in motor deficit, in the cervical and thoracic spine there is also a risk of spinal cord compression in severe cases.
Disc herniation (termed as intervertebral disc displacement) is a type of spinal disease based on IDD or not, with local pain and/or sciatica due to mechanical compression and autoimmune cascades upon the corresponding nerve roots.
