        • lateral
          • vertically positioned talus & dorsal dislocation of navicular
            • line along long axis of talus passes below the first metatarsal-cuneiform axis
              • before ossification of navicular at age 3, the first metatarsal is used as a proxy for the navicular on radiographic evaluation
        • AP
          • talocalcaneal angle > 40° (20-40° is normal)
      • alternative views
        • forced plantar flexion lateral radiograph is diagnostic
          • shows persistent dorsal dislocation of the talonavicular joint
            • oblique talus reduces on this view
            • Meary's angle > 20° (between line of longitudinal axis of talus and longitudinal axis of 1st metatarsal)
        • forced dorsiflexion lateral
          • reveals fixed equinus
    • MRI
      • neuraxial imaging should be performed to rule out neurologic disorder
