Degenerative disc disease is misnomer, because it’s not really a disease. It is a term that refers to the normal changes in the spine as we age. In particular, it refers to the deterioration of our spinal discs, which are the soft, cushiony discs between our bony vertebrae.
Spinal discs are like shock absorbers, in that they separate the bones and allow the spine to bend, twist, and flex. Degenerative disc disease usually occurs in the lumbar region of the spine (lower back) and the cervical region (neck). It results in
These conditions can lead to pain and nerve problems, due to pressure on the nerves and spinal cord.
The cause of degenerative disc disease is aging. Aging leads to a loss of fluid in the discs, making them more brittle and less flexible. They also become thinner, which brings the vertebrae closer together. In addition, small cracks or tears in the discs may cause leakage of the jellylike material inside. This causes bulging, breaking, or fragmenting of the discs.
Degenerative disc disease does not affect everyone the same way and at the same rate. It is usually worse among smokers and those who do heavy physical labor that taxes the spine. People who are overweight and obese tend to have worse symptoms as well. A sudden injury can also initiate the process of deterioration.
When the discs between the vertebrae get thinner, there is less cushion for the spine and it loses stability. In response, the body generates bone spurs, also known as osteophytes, which can cause pain due to pressure on the spinal nerves. The pain may be felt in the back or the neck, depending on the person and the location of the degeneration. Discs that are affected in the neck region can lead to pain in the arms or neck, while affected discs in the lumbar or lower region can lead to leg, back, or buttock pain.
Your doctor or chiropractor can diagnose degenerative disc disease through the use of a physical examination and a medical history. He or she will look for areas of tenderness, range of motion, pain, numbness, reflexes, and any additional conditions such as fractures or infections. Imaging tests are not particularly useful for degenerative disc disease. Treatment usually includes ice or heat, anti-inflammatory medications, and rest. Stretches and physical therapy are often recommended. In severe cases, surgery may be recommended to remove the damaged disc(s).
