Boutonniere deformity is a condition where the middle joint of the finger becomes bent downward while the fingertip joint sticks out. It usually occurs due to a traumatic injury that damages the tendons. Treatment involves splinting the affected finger to straighten the middle joint while allowing movement at the fingertip joint. In some cases, surgery may be necessary to repair the damaged tendons. Seeking medical attention for proper evaluation and management of boutonniere deformity is essential to prevent long-term functional impairment and joint stiffness.
