M12: Other specific arthropathies
M12.0: Chronic postrheumatic arthropathy [Jaccoud]
Chronic postrheumatic arthropathy, also known as Jaccoud's Arthropathy, is a joint disorder that commonly occurs following rheumatic fever. This condition generally affects the small joints, particularly those in the hands and feet, causing deformities that can appear similar to those seen in rheumatoid arthritis. However, unlike rheumatoid arthritis, the joint changes in Jaccoud's Arthropathy are reducible, meaning they can be moved back into their correct position. Symptoms may include joint pain, swelling, stiffness, and difficulty in carrying out normal movements due to joint deformities. Over time, this condition may lead to a decline in physical function. Despite causing deformities, it does not usually cause the bone erosion commonly seen in other types of inflammatory arthritis.
