Background

  • Uncommon due to firm attachment of skin and subq tissue to underlying bone
  • When dislocations do occur usually are dorsal

Clinical Features

Differential Diagnosis

Hand and finger dislocations

Evaluation

Management

Dorsal/Posterior

  • 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

Volar/Anterior

  • Flex wrist then hyperflex the affected joint
  • Apply gentle traction then extend the joint
  • Often need open reduction due to volar plate entrapment

Splinting

  • Splint in slight flexion with dorsal splint x 3wk
