Radiographs for Ankle Fractures


- See: Radiographic Studies of the Foot and Ankle

- Lateral of Ankle:

- Mortise Views:
     - syndesmotic injury;
     - medial clear space should be less than 4 mm and superior- medial joint space w/ in 2 mm medially of its width laterally;
            - due to the obliquity of the medial malleolus, measurement of medial clear space can be difficult on the Mortise view (in this case use AP view);
     - talar tilt
     - tibiofibular line
     - talocrural angle

- AP
     - medial clear space should be less than 4 mm and superior-medial joint  space w/ in 2 mm medially of its width laterally;
            - often, it is easier to measure medial clear space on AP view rather than mortise view due to obliquity of  medial mortise;
     - space between medial wall of fibula & incisural surface of tibia < 5 mm
     - anterior tubercle of tibia should overlap fibula by atleast 10 mm;
     - second method is to draw a line down the center of the tibia, & through center of the talar dome on both the AP and lateral x-ray;
            - mortise width is usually 4 mm
