What is Degenerative Disc Disease
The spine is made up of 24 moveable bones called vertebrae and are protected with natural cushioned shock absorbers called discs. The discs also create a passageway or nerve hole (foramen) between the vertebrae for nerves to exit from the spinal cord located in the spinal canal. The nerves in turn connect to all cells, tissues and organs.
The discs are made of soft connective tissue composed largely of collagen and water which keeps the disc firm and resilient. However, due to a combination of trauma and aging it’s possible for the disc to undergo wear and tear, causing a loss of some of its water, leading to thinning and weakening the disc. This disc thinning leads to a reduction of its vertical height as well as the size of the opening of the nerve passageway. This shorter disc and nerve passageway often leads to nerve irritation as well as back pain. Although degeneration of the spinal discs is commonly believed to be a normal part of aging, the effects can be so painful, anything but normal.
