Overview

The calcaneus bone known as the largest tarsal bone.

Historical Perspective

In early 1990s,Lorenz Böhler (1885-1973) introduced the Böhler's angle.

Böhler’s angle

Böhler’s angle (Bohler angle, Boehler angle, calcaneal angle, or tuber joint angle): 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.
