Degenerative disc diseaseImage:Slipped Discs.jpg Degeneration of the intervertebral disc, which is often called degenerative disc disease (DDD) or osteoarthritisof the spine, is a common disorder of the lower spine. Disc degeneration can lead to disorders such as spinal stenosis(narrowing of the spinal canal that houses the spinal cord and nerve roots; can be lumbar or cervical), spondylolisthesis(forward slippage of the disc and vertebra), and retrolisthesis(backward slippage of the disc and vertebra) (Fig. 1). Actually, DDD is not a disease but, rather, a degenerative condition that can be painful and can greatly affect your quality of life. Disc degeneration is a normal part of aging and is generally not a problem by itself. However, when bone spursgrow adjacent to the discs, they can pinch or put pressure on the nearby nerve roots or spinal canal, and pain can occur.
CausesAging is the most common cause of disc degeneration. As the body ages, the discs in the spine dehydrate, or dry out, and lose their ability to act as shock absorbers between the vertebra. The bones and ligaments that make up the spine also become less flexible and thicken. Unlike muscles, there is minimal blood supply to the discs so they lack the ability to heal or repair themselves. SymptomsOften, patients suffering from DDD do not show symptoms. When symptoms are present, however, chronic low back painsometimes radiates to the hips, or there is an aching painin the buttocksor thighswhile walking. Similar pain may be felt or may increase while sitting, bending, lifting, and twisting. While the degeneration of the disc will likely progress as a natural part of the aging process, pain symptoms such as low back pain often decrease over time. Understanding disc painIt is not clear why some degenerative discs are painful and some are not. After an injury, some discs become painful because of inflammation. Some people have nerve endings that penetrate more deeply into the annulus fibrosus, or outer layer of the disc, than others, making the disc more susceptible to becoming a source of pain. Pain that radiates down the leg, known as sciaticaor lumbago, is the result of the nerve root encountering the inner disc material, or the nucleus pulposus, an inflammatory substance that also puts pressure on the nerve. These conditions can cause symptoms such as severe leg pain, difficulty standing and walking, and weakness or numbness in the legs. DDD can lead to a chronic debilitating condition and can have a serious negative impact on a person's quality of life. When DDD is severe, traditional nonoperative treatment is often ineffective. Image:Degenerative disc options.jpg Treatment optionsOften, DDD can be successfully treated without surgery. Physical therapy, anti-inflammatory medications such as nonsteroidal anti-inflammatory drugs, chiropractictreatments, or spinal injections often provide adequate relief of these troubling symptoms. Surgery may be recommended if the conservative treatment options do not provide relief within 2 to 3 months. If leg or back pain limits normal activity, if there is weakness or numbness in the legs, if it is difficult to walk or stand, or if medication or physical therapy are ineffective, surgery may be necessary, most often spinal fusion. Osteopathic treatment treats various aspects of the degenerative process returning the back to optimal functioning. The treatment involves gentle stretches and manipulation to the facet joints of the spine. Relaxation techniques to the resultant muscle spasm. The osteopath will not just treat the degenerate area but treat the whole spine. References
