Overview
The calcaneus bone known as the largest tarsal bone[1].
Historical Perspective
In early 1990s,Lorenz Böhler (1885-1973) introduced the Böhler’s angle[2].
Böhler’s angle
Böhler’s angle (Bohler angle, Boehler angle, calcaneal angle, or tuber joint angle)[3][4][5]: Is located through two lines tangent to the calcaneus: the anterior and posterior aspects of the superior calcaneus and in normal healthy non-fractured calcaneal bone is ranged from 20° to 40°. The lateral radiograph gives the best view of this angle. A value less than 20° can be seen in calcaneal fracture. In calcaneal fracture this angle decreases.
These two angles are useful for the calcaneal fracture severity evaluations and the related surgical managements.
-
Normal Bohler’s angle. -
Calcaneal fracture with a decreased Bohler angle to 14 degrees.
