Discectomy is the most common surgical treatment used for herniated discs. Intervertebral discs are substances located between the bones of the spine and firmly attached to the vertebrae, connecting the vertebrae. Ruptures occur when the outer surface of the disc, called the ‘annulus fibrosus’, weakens due to age and injuries. The inner soft, flexible part of the disc called ‘nucleus pulposus’ deteriorates, moves out of place and protrudes through the tears in the outer layer. Slipping, sagging and bulging of the disc is called herniation. In the medical literature, disc herniation is called disc herniation. When the inner disc material exceeds the posterior outer surface border, it can put pressure on very sensitive nerve tissue. A bulging disc can compress or damage the nerve root, resulting in pain referred to one or both legs, loss of strength, and numbness, depending on the nerve root or nerve roots it affects.
