Boutonniere deformity treatment: Which splinting approach is recommended?

Boutonniere deformity results from disruption of the extensor mechanism at the PIP joint, which causes the PIP to flex and the DIP to hyperextend. The aim of treatment is to realign the extensor mechanism and prevent PIP flexion while allowing the DIP to move and glide, promoting healing. Splinting the PIP in extension keeps the PIP straight, preventing further flexion contracture and giving the central slip a chance to heal. At the same time, performing isolated DIP flexion exercises keeps the DIP moving and helps re-tension the extensor mechanism as healing occurs. This combination addresses the dysfunction at both joints without encouraging worsening deformity. Immobilizing the hand with a resting splint and no movement won’t promote tendon gliding or healing. Splinting the PIP in flexion would worsen the deformity by maintaining a flexed PIP. Starting active full finger ROM immediately risks aggravating the injury and hindering proper healing.
