Calcaneal inclination angle
The calcaneal inclination angle (also known as the calcaneal pitch) is drawn on a weightbearing lateral foot radiograph between the calcaneal inclination axis and the supporting horizontal surface. It is a measurement that reflects the height of the foot framework, but is affected by abnormal p...
Talar declination angle
The talar declination angle is drawn on the weightbearing lateral foot radiograph between the mid-talar axis and the supporting surface. It should usually measure approximately 21°. If the first metatarsal axis is steep, the mid-talar axis approaches the horizontal and is projected above the fi...
Angle of the longitudinal arch (foot)
The angle of the longitudinal arch is one of the angles drawn on the weightbearing lateral foot radiograph. The angle is formed between the calcaneal inclination axis and a line drawn along the inferior edge of the 5th metatarsal. The normal angle is 150-170°. In pes cavus, as the height of th...
