Calcaneal inclination angle

Dr Owen Kang and Dr Jeremy Jones et al.

The calcaneal inclination angle (also known as the calcaneal pitch) is drawn on a weight-bearing 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 pronation or supination of the foot:

  • low: 10-20° - indicative of pes planus when <18°
  • medium: 20-30° - i.e. normal
  • high: ≥30° - indicative of pes cavus
