What are swan neck and boutonnière deformities, and are they associated with RA or OA?

1) Swan neck deformity is associated with RA and boutonnière deformity is associated with OA.
2) Swan neck deformity is associated with OA and boutonnière deformity is associated with RA.
3) Both swan neck and boutonnière deformities are associated with RA.
4) Both swan neck and boutonnière deformities are associated with OA.

Answer :

Final answer:

Swan neck and boutonnière deformities are both associated with rheumatoid arthritis (RA).

Explanation:

Swan neck and boutonnière deformities are both associated with rheumatoid arthritis (RA). In RA, the joint capsule and synovial membrane become inflamed, leading to joint deformation. Swan neck deformity occurs when the finger joints become hyperextended at the middle joint and flexed at the end joint, resembling a swan's neck. Boutonnière deformity, on the other hand, is characterized by flexion of the proximal interphalangeal joint and hyperextension of the distal interphalangeal joint. These deformities are typical of RA and not associated with osteoarthritis (OA).
