IV. Management: Reduction

  1. Digital Nerve Block
  2. Apply traction while hyperextending dip joint
  3. Apply pressure to base of distal phalanx
  4. Return phalanx to position by flexing dip joint

V. Management: Post-Reduction

  1. Post-reduction joint assessment
    1. Assess joint range of motion
    2. Assess collateral ligaments with DIP flexed
  2. Immobilization
    1. Dorsal splint for 2 weeks in 20-30 degrees of flexion
  3. Referral Indications
    1. Complicated dislocation

VI. Complications
