Body was changed:

Böhler angle,also written as Bohler angle or Boehler angle, is also called the calcaneal angle or tuber joint angle 1, and is the angle between two lines tangent to the calcaneus on the lateral radiograph. These lines are drawn tangent to the anterior and posterior aspects of the superior calcaneus.

The normal value for this angle is between 20° to 40°. A value less than 20° can be seen in calcaneal fracture. However, a normal Böhler angle does not exclude a calcaneal fracture.

History and etymology

Lorenz Böhler (1885-1973) was an Austrian surgeon, regarded as the founder of traumatology 4.
