Disc protrusion

Disc protrusion

A disc protrusion is a disease condition which can occur in some vertebrates, including humans, in which the outermost layers of the annulus fibrosus of the intervertebral discs of the spine are intact, but bulge when one or more of the discs are under pressure.

A disc protrusion may progress to a spinal disc herniation, a condition in which there is a tear in the annulus fibrosus.
