Common Spine and Disc Problems

The most common serious back problems happen when discs tear, bulge, or rupture. In such cases, an injured disc can no longer cushion the vertebrae and absorb shock. As a result, the rest of your spine may also weaken. This can lead to pain, stiffness, and other symptoms.

• Torn annulus. A sudden movement may cause a tiny tear in an annulus. Nearby ligaments may stretch.
• Contained herniated disc. As a disc wears out, the nucleus may bulge into the annulus and press on nerves.
• Extruded herniated disc. When a disc ruptures, its nucleus can squeeze out and irritate a nerve.

• Arthritis. As discs wear out over time, bone spurs form. These growths can irritate nerves and inflame facets.
• Instability. As a disc stretches, the vertebrae slip back and forth. This can put pressure on the annulus.
• Spondylolisthesis. Listhesis is a condition in which one vertebra has moved forward or backward, in relation to the one above or below it. This causes a crack (stress fracture) in the areas that link the vertebrae together. This may put pressure on the annulus, stretch the disc, and irritate nerves.
