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, & thru center of the talar dome on both the AP and lateral x-ray;
- mortise width is usually 4 mm;
