We can modify some of these risk factors, but the others are inherent and not modifiable. There are several factors that can increase the risk of osteoarthritis. Over time, the disc cartilages and facet joints tend to wear out. This is because of the millions of flexions, extensions and rotary movements made by the joints in the neck. The neck also is susceptible to arthritis. When a person stands upright, the lumber spine experiences additional strain and wears out faster than nonmobile levels like the middle of the spine. It's most common in the lower back, or lumbar spine, because these joints carry most of the body weight. The spine is susceptible to osteoarthritis because of the motion between the vertebrae. You can get this type of arthritis at any age, but it is usually more common in adults 40 or older. You may experience pain and swelling, and your bones and joints slowly erode and deform. Rheumatoid arthritis is caused when your body's immune system mistakenly attacks your joints. Osteoarthritis is the most common type of arthritis. Degenerative changes can happen over time in joints used daily for motion. Osteoarthritis occurs when the cartilage that caps your bones wears away. The most common types of arthritis are osteoarthritis and rheumatoid arthritis. Arthritis can affect various joints in the body that are load-bearing and where movement occurs, including the spine. The spine comprises 33 bones stacked one over the other like Lego blocks, connected by three different joints. It's common in the joints used daily, such as the hands and knees. Over time, the cartilage in joints can break down and cause swelling and tenderness. All these components work together to make movement easy. A membrane, called the synovial membrane, lines the joint and is filled with fluid known as synovial fluid. Joints are physical points of connection between two bones, and cartilage is the tissue that covers the surface of the bone at the joint. Many types of arthritis can affect your musculoskeletal system.
