On the lateral foot weightbearing radiographs, the naviculocuboid overlap (A/B) is the overlapped portion of the navicular and cuboid divided by the vertical height of the cuboid. The relative calcaneal length (C/E) is the distance between midpoint of the anterior articular surface of the calcaneus and the most posterior aspect of the calcaneus divided by the width of the widest portion of the distal tibial. The calcaneocuboid subluxation was the angle between a line drawn through the midpoint of the articular surface of the calcaneus and the most posterior aspect of the calcaneus (C) and a line drawn through the midpoint of the articular surface of the cuboid and the most posterior aspect of the calcaneus (D).
