Millions of people suffer from arthritis. In fact, arthritis affects approximately 80% of people over the age of 55 in the United States. It is estimated that by the year 2020, over 60 million people will suffer from this often-disabling problem.
Arthritis is actually a term for over 100 rheumatoid disorders. Common forms include:
Osteoarthritis
Rheumatoid Arthritis
Ankylosing Spondylitis
Juvenile Arthritis
Psoriatic Arthritis
Systemic Lupus Erythematosus
Arthritis can affect any part of the body, even the spine. The information provided in this article focuses on arthritis and the spine.
Quick Anatomy Lesson - The Spine
The spine is made up of individual bones called vertebrae, which provide support for the spine. These vertebrae are connected in the front of the spine by intervertebral discs that help support the spine and also allow it to move. The many ligaments and muscles that are attached to the back of the spine provide the power for movement.
Arthritis occurs when the cartilage in the joints is worn down as a result of wear and tear, aging, injury or misuse. Osteoarthritis, the most common form of arthritis, also includes loss of cartilage, overgrowth of bone and the formation of bone spurs. This causes the bones under the cartilage to rub together, causing pain, swelling and loss of motion of the joint. Osteoarthritis can occur in any joint but most often occurs in the hips, knees, hands or the spine.
Osteoarthritis and the Spine
In the spine, osteoarthritis can cause stiffness and pain in the neck or in the lower back. Cervical arthritis (also called cervical spondylosis) affects the upper spine and neck. Lumbar or lumbosacral arthritis affects the lower back and pelvic area. Ankylosing Spondylitis is another type of spinal arthritis.
Who Gets Arthritis and Why?
Some people are more at risk for developing arthritis than others. The following are some factors that contribute to a person's risk of developing arthritis:
Age: arthritis is more common in people over the age of 50
Overused joints from work or sports related activities
Injury or trauma to the bones (like fractures)
Obesity: excessive weight places stress on joints
Family history
Gender: women are twice as likely to get arthritis
Chronic illness such as diabetes, cancer or liver disease
Weakened immune system
Infections such as Lyme disease.
