What is annulus fissure?

What is annulus fissure?

An annular fissure is a type of discogenic condition that affects the spine. It usually occurs when the fibers that make up the tough outer covering of the intervertebral disc either break or separate. Collectively, these fibers are known as the annulus fibrosus.

Annular fissures are a degenerative deficiency of one or more layers that make up the annulus fibrosus of the intervertebral disc.

Why is the posterior annulus a high intensity zone?

A high intensity zone (HIZ) generally occurs due to: HIZs in the posterior annulus represent the in-growth of the vascularized granulation tissue into the tears in the posterior part of the painful disc induced by inflammation.

What causes a narrowing of the foraminal foramen?

Degenerative spine conditions like a herniated disc, a bulging disc, bone spurs or spondylolisthesis are the primary reason that the foramina become narrower. While foraminal stenosis is not in and of itself painful, a narrowed foramen often exerts pressure on a nearby spinal nerve, which can lead to the painful symptoms outlined below.

What does a high intensity Zone ( HIZ ) mean?

If you have a High Intensity Zone (HIZ) then you are suffering with an area in a ‘disc (s)’ of soft tissue which separate the vertebrae in the spinal column, which on the MRI scan has increased intensity. It may be described as an Annular Tear. The HIZ may represent: An area of healing (Granulation tissue) within the disc and wall of the disc.

Can a foraminal herniated disc be diffuse or focal?

Foraminal Herniated Disc Discussion. Foraminal herniations can be focal or diffuse and many are also classifiable as other types of herniations, including paramedian bulges. Treatment options for pinched nerves are often incredibly unenlightened.

What causes an annular fissure in the spine?

What is an Annular Fissure? An annular fissure is a condition that affects intervertebral discs. Most of the time a fissure is caused by degenerative changes in the spine, including age-related drying out of the discs, but it can also be brought about by trauma.

What causes a fissure in the intervertebral disc?

Annular Fissure Causes and Treatment. It usually occurs when the fibers that make up the tough, outer covering of the intervertebral disc either break or separate. Collectively, these fibers are known as the annulus fibrosus. Annular fissure is also called annular tear, although there are differences between the two terms.

Foraminal Herniated Disc Discussion. Foraminal herniations can be focal or diffuse and many are also classifiable as other types of herniations, including paramedian bulges. Treatment options for pinched nerves are often incredibly unenlightened.
