Talocalcaneal angle

The talocalcaneal angle (also known as kite angle) refers to the angle between lines drawn down the axis of the talus and calcaneus measured on a weightbearing DP foot radiograph. This angle varies depending on the position of the calcaneus under the talus and the stiffness of the ligaments of the foot. 

The mid-talar line should pass through (or just medial to) the base of the 1st metatarsal and the mid-calcaneal line should pass through the base of the 4th metatarsal.

The talocalcaneal angle measure be between 25 and 40 degrees. When the angle between the talus and calcaneus is reduced, the two bones are relatively parallel and the angle approaches zero.
