Consider digital block for pain control
Flex wrist, then hyperextend the joint
Apply longitudinal traction followed by dorsal pressure to phalanx base
Irreducible dislocation likely due to entrapment of avulsion fracture, profundus tendor or volar plate
Without initial hyperextension, can be difficult to disengage from any trapped soft tissue
Post reduction, look for central slip rupture, which may lead to Boutonniere deformity
Without initial hyperextension, can be difficult to disengage from any trapped soft tissue
Flex wrist then hyperflex the affected joint
Apply gentle traction then extend the joint
Often need open reduction due to volar plate entrapment
Splint in extension with dorsal splint
