- Discussion:
- ORIF is recomened when:
  - > 25% of posterior articular surface is involved;
     - fragment must have a tibial articular surface that is large enough to provide a stable wt bearing surface;
  - fracture is displaced more than 2 mm;
  - there is posterior subluxation of talus;
     - even slightlest posterior subluxation of talus on articular surface of tibia is not acceptable;
  - if frx prevents reduction of fibula;
  - valgus tilt of talus in postreduction film may be a relative indication
