Classification & external resources

Not to be confused with spondylitis, spondylolysis or spondylolisthesis.

Spondylosis is spinal degeneration and deformity of a joint(s) of two or more vertebrae that commonly occurs with aging. Often there is herniation of the nucleus pulposus of one or more intervertebral discs and/or formation of osteophytes.

When the space between two adjacent vertebrae narrows, compression of a nerve root emerging from the spinal cord may result in sensory system and motor system disturbances, such as severe pain in the neck, shoulder, arm, back, and/or leg, accompanied by muscular weakness. Less commonly, direct pressure on the spinal cord may result in global weakness, gait dysfunction, loss of balance, and loss of bowel and/or bladder control. If vertebrae of the neck are involved it is labeled Cervical Spondylosis. Lower back spondylosis is labeled Lumbar Spondylosis.

Neck pain can be relieved by wearing a hard collar around the neck which keeps the affected vertebrae slightly apart, and hence the pressure on the nerves is released. However, the use of a collar is not usually recommended as it can weaken the muscles supporting the vertebrae and hence exacerbate the problem in the long term.

Physiotherapy, where the neck is exercised, is now generally used as the preferred treatment.

Chiropractic treatment of mild cases of the disease is not the preferred method of treatment by conventional medicine.

Acupuncture, while often effective when neuropathy results from muscle dysfunction or inflammation, symptoms resulting from bony deformities are unlikely to get better.

Injections of the spinal joints can be useful for relief of acute pain for otherwise intractable discomfort. Naturally, any spine injection should be performed by a physician with training in spine injection techniques. These injections should be done with xray assistance (flouroscopy) to ensure accuracy.

Evidentiary support for mobility (physiotherapy) or manipulative (chiropractic) therapies has shown an observed improvement in perceived pain and immobility in mechanical neck disorders. However such therapies are not supported as being of greater use in relieving pain and inflammation than conventional medicine and neither was identified as being superior to the other. [1]

There are many different surgical procedures to correct spinal deformity. The vertebra can be approached by the surgeon from the front, side, or rear. Portions of a disc may be removed. To prevent further dislocation, fusion of two vertebrae may be done by taking pieces of bone from the patient's hip and inserting them between the two vertebrae which are fused together and secured by screws.
