Low back pain is one of the most common causes of healthcare visits in the United States, accounting for over 45 million trips in 2006. Spine osteoarthritis is a primary source of chronic low back pain.

Epidemiology

Radiographic evidence of spine osteoarthritis is widespread. In patients over the age of sixty, 95% of men and 70% of women have at least one indicator of arthritis. Cervical spine osteoarthritis is present in over 80% of individuals over the age of 55.[7] Specifically, facet joint arthritis is present in 19% of individuals between the ages of 45 and 65 years of age and 57% of patients over the age of 65 in the United States.[6] There have been no reported studies indicating the prevalence of thoracic facet joint arthritis.[7] Lumbar spine osteoarthritis affects approximately 30% of men and 28% of women from the ages of 55 to 64 in the United States. The L4-5 and L5-S1 vertebral levels are most commonly affected due to their higher load and joint mobility.[2] A separate study found lumbar osteoarthritis-related back pain in over 20% of men and 22% of women between the ages of 45 and 64.[7] Sixty-seven percent of patients between the ages of 45 to 64 and 89% of patients over 65 had evidence of facet joint arthropathy on imaging.[6]
