TibioFibular Line

- Discussion:
    - on mortise view line formed by subchondral bone of distal tibia & medial spect of the fibula should be continuous;
    - articlar surface of talus should be congruous w/ that of distal fibula (called tibiofibular line);
    - disruption of this line indicates:
          - shortening
          - rotation
          - lateral displacement fibula;
          - tear in portion of syndesmotic ligaments
