If lateral views of the ankle are obliqued along the horizontal plane, the talar domes no longer overlap. Similarly, the medial (black arrows) and lateral (pink arrows) inferior margins of the talus can separate and fool you into calling a fracture. The posterior margin (white arrow) can also simulate a cortical defect.
