What causes herniation of nucleus pulposus?

The most common cause of disc herniation is a degenerative process in which, as humans age, the nucleus pulposus becomes less hydrated and weakens. This process will lead to a progressive disc herniation that can cause symptoms. The second most common cause of disc herniation is trauma.

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 is the mechanism of disc herniation?

Typical Mechanism of Injury: A herniated disk may occur because of gradual degeneration of the disk or from an injury like a slip and fall or a car accident. Repetitive twisting and turning activities may lead to disk degeneration, and poor posture while lifting can cause disk damage.

Which symptoms would occur with a herniated nucleus pulposus?

Nucleus pulposus herniation can produce low back pain; however, the primary clinical manifestation is a radiculopathy, which is mainly manifested by radiating pain and sensitive changes that encompass nerve distribution.

What does the nucleus pulposus represent?

Nucleus pulposus is the inner core of the vertebral disc. The core is composed of a jelly-like material that consists of mainly water, as well as a loose network of collagen fibers. The elastic inner structure allows the vertebral disc to withstand forces of compression and torsion.

Can herniated nucleus pulposus be fixed?

Usually, a herniated nucleus pulposus only becomes apparent when the displaced disc material interrupts the spine’s structural integrity or begins to compress nearby nerves, ligaments and tissues. A disc with a herniated nucleus pulposus can almost always be managed or fully repaired through proper treatment.

What does the nucleus pulposus do?

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.

What is the nucleus pulposus made of?

Nucleus pulposus is the inner core of the vertebral disc. The core is composed of a jelly-like material that consists of mainly water, as well as a loose network of collagen fibers.

How do you assess a herniated nucleus pulposus?

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.

What contains the nucleus pulposus?

How does nucleus pulposus receive nutrients?

Cells inside the nucleus pulposus (NP) mainly rely on nutrient transport to and from the vertebral capillaries,9, 10 which can be compromised by several factors. The vertebral capillaries penetrate pores in the bony endplate and terminate adjacent to the cartilage endplate (CEP)11, 12 (CEP; Fig. 1).
