Herniated Discs (Disc Prolapse)
Disc herniation is a broad term referring to a tear in the outer ring (annulus, thus allowing the soft gelatinous matter to leak out through the tear.
The intervertebral disc is responsible for the attachment of vertebral bodies to each other, providing flexibility and absorbing and distributing the loads applied to the spinal column. With aging, the disc undergoes significant changes in volume and shape as well as in biochemical composition and properties. Lumbar disc herniations are believed to result from anular degeneration that leads to a weakening of the anulus fibrosus, leaving the disc susceptible to annular fissuring and tearing.
