Disc Protrusion

Posterolateral Disc Protrusion

The term posterolateral disc protrusion is another way to describe the location of the occurrence of a disc bulge in relation to the disc itself. In this case, posterolateral means that the disc protrudes between the side of the disc and the entrance of the intervertebral foramen (the opening where the spinal nerve passes).

Anterior Disc Protrusion

An anterior disc protrusion occurs when the inner part of the disc (the nucleus pulposus) bulges into the front part of the outer ring (the annulus fibrosus). This makes it the exact opposite of the posterior disc protrusion, where the disc wedges itself backwards. Anterior protrusions are not as common as posterior bulges and are […]

Midline Disc Protrusion

A midline disc protrusion, also called central disc protrusion, usually occurs at the lower back and is mostly painful, since it typically impinges the nerve root directly. The technical word midline is used to specify the position of the protrusion in relation to the disc. Hence in this case, the bulge is located toward the […]

Extraforaminal Disc Protrusion

As with many of the other types of disc protrusion, the medical term extraforaminal disc protrusion merely indicates the precise location of the disc bulge. Other than a foraminal, or intraforaminal disc protrusion, this one occurs outside the foramen (that’s the opening of the backbone were the spinal nerve passes).

Intraforaminal Disc Protrusion

An intraforaminal disc protrusion is basically the same thing as a foraminal disc protrusion. The term intraforaminal is merely used in order to show the distinction to the extraforaminal disc protrusion. These terms are only used to characterize the position or location of the actual protrusion of the disc. Hence, an intraforaminal protrusion is located […]

Foraminal Disc Protrusion

The thing that sets apart a foraminal disc protrusion from a regular disc protrusion is the location of the pressure that the disc puts on the spinal nerve. In this case the compression mostly occurs on the superiorly exiting nerve root, meaning above the actually protruding disc. Due to this particularity, it is not quite […]

Posterior Disc Protrusion

A posterior disc protrusion is a disc protrusion where the affected disc has bulged backwards and therefore can more easily put pressure on the sensitive spinal nerve roots. The symptoms of a posterior disc protrusion can include radiating leg and arm pain, local back pain, numbness and tingling as well as sciatica.

Central Disc Protrusion

A central disc protrusion is a disc protrusion where the bulge of the affected disc is pointing towards the middle part of the spinal canal. The spinal canal is the place where the nerve roots as well as the spinal cord can be found. Thus, as a result of the pressure generated by the central […]

Broad Based Disc Protrusion

A disc protrusion that encompasses more than 25% and up to 50% of the circumference of the disc itself, is called broad based disc protrusion. So basically the term “broad based” only refers to the actual size of the bulge and nothing else. It does not mean that having a broad based disc protrusion is […]

Share

Focal Disc Protrusion

A focal disc protrusion is in a way the opposite of a broad based disc protrusion when it comes to both its classification and to some degree its severity. A disc protrusion is called focal, when the actual bulge has a very small size, more precisely less than 25% of the circumference of the entire […]
