A 12-year-old patient presents with pain on the lateral side of the right ankle when standing. The subtalar joint is restricted in motion, and pain is elicited on palpation of the fibular (peroneal) tendons. If the medial oblique view of the foot is negative, which of the following views will probably be positive?
1) Harris-Beath (calcaneal axial)
2) Anteroposterior
3) Sesamoidal axial
4) Mortise ankle
