What is a Disc Protrusion?Disc protrusion is a term used to describe the shape of a certain type of herniated spinal disc. In turn, herniated discs are discs that have undergone changes in their shape and structural integrity that can lead to back pain or other problems. Doctors consider disc protrusions relatively mild in comparison to other types of disc herniation.
Spinal Disc Basics
The discs that sit between each of your spinal bones (vertebrae) serve several basic purposes. First, they keep your bones from rubbing against each other when you move your back or neck. They also cushion the length of your spine and help protect you from jarring physical contact, as well as daily wear and tear. In addition, the spinal discs help maintain spine flexibility by maintaining the proper distance and spacing between each individual vertebra. Each disc has two essential parts: a tough, ligament-like outer covering called the annulus fibrosus and a spongy or gel-like inner core called the nucleus pulposus.
