Calcaneus Fracture

Return to Main Menu

Calcaneal fractures are not unusual. A "lover's" fracture is a common calcaneal fracture, resulting from an axial load type of injury (falling). Radiographically, there is a decrease in Boehler's angle to less than 20 %. Moreover, 75 % of these fractures involve the subtalar joint and 10 % are bilateral. Associated fractures with the same axial load mechanism include burst fractures of the spine ("Don Juan" fracture) and pilon fractures of the distal tibia.

 - Click on the image for a larger versionBLateral radiograph of the ankle. This shows flattening of Boehler's angle and sclerosis through the calcaneus.
