What is the difference between protrusion and extrusion?

A protrusion exists when only a few cartilage rings are torn and there is no actual leakage of the center material; the disc protrusion looks like a “bump”. With an extrusion, all the cartilage rings have torn in a small area, allowing the jelly-like material to flow out of the disc.

What is disc protrusion and extrusion?

The jelly-like inner core breaks through the fibrous outer layer and leaks out into the spinal canal. The inner core material remains attached to the disc. This type of herniation may start as a disc protrusion and progress to a disc extrusion.

Is a disc protrusion the same as a ruptured disc?

The bulged disc material is still contained within the annulus. But in some cases, the nucleus pushes completely through the annulus and squeezes out of the disc. This is called a disc herniation or protrusion. Herniation and protrusion are two words for the same thing.

What is extrusion of disc?

A disc extrusion is a type of severe disc herniation. It happens when the center – or nucleus – of an intervertebral disc escapes from the center of the disc. A disc that is extruded can occur in the neck, mid, or lower back, and can cause severe spinal related pain.

What is the difference between a protrusion and an extrusion?

The term “Protrusion” refers to a disc herniation in which the portion of disc material that is outside the normal confines of the disc space is equal to or less than its aperture where the disc material extrudes from the parent disc. Examples of disc “Protrusions” and “Extrusions” are shown in the below images.

Which is the best definition of disc extrusion?

disc sequestration is an extrusion where the disc material migrates and becomes separated from the rest of the herniation.

What’s the difference between a disc bulge and a disc protrusion?

Disc Extrusion, Protrusion, and Sequestration. Disc Protrusion: Commonly called a disc bulge, a disc protrusion occurs with the spinal disc and the associated ligaments remain intact, but form an outpouching that can press against the nerves. Disc Extrusion: A disc extrusion occurs when the outer part of the spinal disc ruptures,…

What is the difference between disc protrusion and disc sequestration?

Terminology disc protrusion is distinguished form a disc extrusion in that the base of protruded disc material is narrower than its ‘dome’; furthermore this material may extend above or below the disc level. disc sequestration is an extrusion where the disc material migrates and becomes separated from the rest of the herniation.
