Boutonniere deformity

Boutonniere deformity is one of the musculoskeletal manifestations of rheumatoid arthritis in the hand with:

  • flexion contracture of the proximal interphalangeal (PIP) joints
  • extension of the distal interphalangeal (DIP) joints 

The defect appears in the tendon which splays open. The appearance apparently reminded (presumably French-speaking) surgeons of a buttonhole.

History and etymology
