What is a Herniated Disc?

A herniated disc happens when the inner disc material, called the nucleus, seeps through the tough outer wall of the disc. A herniated disc can also be referred to as a slipped disc. There are two main types of herniated discs.

  • Contained herniated disc: a herniated disc is considered contained if the inner material of the disc has not pushed through its outer wall. It is also sometimes referred to as a contained disc herniation.
  • Extruded discs: a herniated disc is considered extruded if the inner material has broken through its outer wall but is still attached to the disc. It is also sometimes referred to as an extruded disc herniation.

If the inner material of the disc has broken away from the disc it is known as a sequestered disc.

What Is the Difference Between a Herniated Disc in the Back and a Herniated Disc in the Neck?

The only difference between a herniated disc in the back and a herniated disc in the neck is that the first will give you pain and symptoms in the neck, shoulder, and arms, while the other will present with symptoms in the lower back, buttocks, legs, and feet.

Healthy Disc Compared to a Disc Herniation

In a healthy disc (1a.) you can notice that the outer wall is thick and tough. As disc degeneration starts to set in this wall will start to thin and dry out allowing for the possibility of cracks or tears. Once a tear or a crack occurs the disc can herniate (1b.) as the inner materials come through and places pressure on surrounding structures.
