Osteoarthritis is the most common type of joint disease, also known as degenerative arthritis. It is result of gradual deterioration of the cartilage in the joint contributing to narrowing of the joint space, resulting in abnormal biomechanics and inflammatory joint disease which results in the formation of bone spurs and bone cysts. The result of arthritis can include joint pain, swelling, stiffness and decreased range of motion. The associated pain can significantly affect the quality of life of those who suffer with arthritis. According to the CDC, (Centers of Disease Control and Prevention) conservative estimates of those affected by osteoarthritis are approximately 13.9% of adults aged 25 and older and 33.6% (12.4 million) of those 65 and older and in 2005 an overall estimate increase from 21 million in 1990 to 26.9 million in 2005. At Salem Pain & Spine Specialists we offer many treatment options available for the various types of arthritis. There are many causes, such as natural process of aging, trauma, infection, autoimmune diseases (i.e. lupus, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis and seronegative spondylarthropathy) or crystal deposition.
