3 Primary Types of Herniated Disc
1.) Contained Disc Herniation:
The 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.
2.) Extruded Disc Herniation:
The 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.
3.) Sequestered Disc Herniation:
If the nucleus has pushed through the annulus and broken away from the disc it is known as a sequestered disc.
Is There a 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 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 as the inner materials come through and places pressure on surrounding structures.
