Ulnar deviation, swan neck, and boutonniere are signs of Rheumatoid Arthritis. It is an autoimmune disease that primarily affects the synovial joints and causes inflammation, stiffness, and pain in these joints. The illness is more common in women, typically between the ages of 40 and 50.
Explanation:
The signs of ulnar deviation, swan neck, and boutonniere are all signs of Rheumatoid arthritis (b). This is an inflammatory disorder that primarily affects the synovial joints of the hands, feet, and cervical spine. Affected joints become swollen, stiff, and painful due to the body's immune system mistakenly attacking healthy tissue. The immune cells from the blood enter joints, causing cartilage breakdown, swelling, and inflammation of the joint lining. This results in bones rubbing against each other, causing pain. Rheumatoid arthritis is more prevalent in women than men, with the common age of onset being between 40 and 50 years.
