Calcaneal inclination angle

Dr Owen Kang and Dr Jeremy Jones et al.

The calcaneal inclination angle is drawn on a weightbearing lateral foot radiograph between the calcaneal inclination axis and the supporting 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
  • medium: 20-30°
  • high: ≥30° - indicative of pes cavus
