Bohler angle

Definition / Description

The Böhler or Tuber-joint angle is an angle of 25-40° between the upper border of the calcaneal tuberosity and a line between the anterior and posterior articulating facets.

With calcaneal fractures, this angle becomes smaller, straighter, and can even reverse.
