The most common serious back problems happen when disks tear, bulge, or burst open (rupture). In such cases, an injured disk 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 disk
As a disk wears out, the nucleus may bulge into the annulus and press on nerves.
Extruded herniated disk
When a disk ruptures, its nucleus can squeeze out and irritate a nerve.
Arthritis
As disks wear out over time, bone spurs form. These growths can irritate nerves and inflame facets.
Instability
As a disk stretches, the vertebrae slip back and forth. This can put pressure on the annulus.
Spondylolisthesis
With this condition, 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 disk, and irritate nerves.
