Calcaneus fracture - Reduced Bohler's angle - Lateral

  • Fractures to the calcaneus usually result in flattening of the bone with reduction in Bohler's angle (normally 28-40°)

  • (Same patient as image above)
  • On the axial view look for fracture lines and breaks in the cortex

Calcaneus fracture - Normal Bohler's angle - Axial

  • (Same patient as image above)
  • In this case the axial image was more informative and shows clear evidence of a fracture

Calcaneus fracture mimics - Lateral

  • The os trigonum is a common accessory ossicle
  • The calcaneus apophysis is not yet fused
  • Neither of these entities should be mistaken for a fracture
