II. Epidemiology

III. Signs: Central Slip Injury

  1. Inability to extend finger at PIP joint

IV. Imaging

  1. Check Post-reduction films for Fracture

V. Management

  1. Reduction
    1. Use similar method as for Dorsal DIP Dislocation
  2. Post-reduction (If reduction completed)
    1. Splint only the PIP in full extension for 6 weeks
  3. Referral Indications
    1. Early orthopedic Consultation in most cases
    2. Fracture involves more than 30-40% of intra-articular surface
    3. Difficult or unsuccessful reduction
    4. Patient unable to fully extend finger

VI. Complications

  1. Difficult reduction with often interposed soft tissue
  2. Usually associated with central slip disruption (avulsion)
  3. Frequently associated with Boutonniere Deformity
