"The ankle AP view is part of a three view series, and visualises the distal tibia, distal fibula, proximal talus and proximal fifth metatarsal."
"SID"
"the tibiotalar joint space should be open, yet the full mortise joint should not be visualised on the AP"
"Although dorsiflexion is essential in both the AP and the mortise view it should be noted that during trauma this may not be possible."
"orientation "
"In addition, this view can show bony diseases or lesions of the distal lower leg, talus and proximal fifth metatarsal."
