The discs allow the spinal column to bend and twist freely and painlessly with the changing position of the body. Without the discs, the bones of the spine would grind and grate on one another. They act as shock absorbers when the body moves, has unusual pressure or forceful jarring.
There are 3 types of disc trouble:
The spine is designed to withstand a great deal of stress and strain, but not a fall, back injury, violent sneeze or a long continued strain may throw a vertebrae out of position, protrude a disc and compress nerves. This is usually called a slipped disc.
When the outer portion of the disc is turned or split and the soft portion protrudes and presses against spinal nerves, this is referred to as a true rupture. But when the outer covering only weakens and bulges, chiropractic adjustments will release the vertebrae from its locked position allowing the disc to return to normal and relieve pressure on the spinal nerves.
