The non-surgical therapy of OA of the spine may include a number of options.
- Physical therapy that strengthens the muscles around the spine can help protect the joints.
- Exercises that maximize the range of motion of joints helps maintain function.
- Obesity can negatively affect functioning of the spine by placing extra strain on spine structures. Losing weight results in less pressure on the spine, relieving strain on the facet joints. In addition, fat cells release chemicals that are pro-inflammatory that may have detrimental effects on joint structures. Lowering levels of these chemicals can have a beneficial effect on the musculoskeletal system.
Medication: Many medications have the potential to decrease pain generated by irritated joints and muscles. These include non-steroidal anti-inflammatories, analgesics, muscle relaxants, and anti-depressants. An increasing concern is the potential toxicities of long-term use of these medicines in older individuals who develop OA of the spine. Side effects of these medications include, gastrointestinal bleeding, elevated blood pressure, and change in mental function.
Facet Joint Block: An alternate to oral medicine is facet joint blocks. Facet joint blocks are injections of a long acting anesthetic around a facet joint. Once the painful joint is identified, the injection can be accomplished with fluoroscopic guidance of the needle to the joint. If the block is successful, a “killing” of the nerve can be accomplished by burning the nerve with radio waves. Alternatively, the nerve can be frozen with a cold probe. In some patients, this procedure can result in decreased pain lasting one to two years at which time the procedure can be repeated.
Surgery: Surgical therapy of osteoarthritis is controversial. Some spine surgeons believe that fusing portions of the spine that are causing only back pain result in individuals with less spine pain. In many circumstances, the individual has traded one spine pain for another. In the neck, the benefits of spinal fusion may be better, but patients remain at risk of progressive osteoarthritis at other levels of the spine.
As a generalization, spine surgery is offered for individuals with leg or arm pain, not those with pain limited to the spine alone. An exception to this rule is spinal instability. Stabilization of the spine can offer symptom relief for those with associated spine pain. The decision to do surgery in this circumstance should only occur after an informed discussion with a spine surgeon
Prevention: Disc degeneration starts in the third decade of life. Minor changes start with the production of abnormal collagen. These collagens appear in the setting of oxidative stress associated with smoking.
- Exercise that strengthens the muscles around the spine are helpful in preventing injuries and more rapid healing.
- The role of obesity in causing back pain is controversial. It is not clear that obesity causes back pain but it is more difficult to resolve an episode of back pain if an individual is obese.
- Sitting is the new smoking. Strong muscles help protect joints from excessive forces. Movement is the best medicine. Getting up frequently has beneficial effects on the spine and the body in general.
