Quizplus · Accepted Answer

On a lateral ankle projection, with the fibula too anterior to the tibia and a narrowed talocalcaneal joint, the lateral dome of the talus will appear more anterior and proximal compared to the medial dome, which will appear more posterior and distal. Therefore, the correct choices are 3 and 4, which are only found in option C.
