Radiographic analysis of the ankle often includes three views: the anteroposterior view, the internal oblique view, and the direct lateral view (15). The anteroposterior view helps assess the ankle mortise through the lateral portions of the talus and tibiotalar joint overlap with the lateral malleolus (16).
A P view Lateral view Internal oblique view Three views of the ankle are mandatory for the evaluation of the ankle following trauma. Some fractures of the medial malleolus may not be apparent on the AP and lateral views but are readily visible on the internal oblique projection.
The AP view (Figure 11-1 A) shows the ankle mortise; however, the lateral margin of the talus and lateral portions of the joint are obscured by the underlying lateral malleolus. Soft tissue swelling seen about the medial and lateral malleolus serves as a useful clue to the presence of an underlying acute fracture. FIGURE 11-1
