Herniated Disc (cont.)

What is a herniated disc? What causes it?

As described above, each disc of the spine is designed much like a jelly donut. As the disc degenerates from age or injury, the softer central portion can rupture (herniate) through the surrounding outer ring (annulus fibrosus). This abnormal rupture of the central portion of the disc is referred to as a disc herniation.

The most common location for a herniated disc to occur is in the disc at the level between the fourth and fifth lumber vertebrae in the low back. This area is constantly absorbing the impact of bearing the weight of the upper body. This is especially important when we are standing or sitting. The lower back is also critically involved in our body's movements throughout the day, as we twist the torso in rotating side to side and as we hinge the back in flexion and extension while bending or lifting.
