Gissane’s angle

The calcaneus bone known as the largest tarsal bone^[1].

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

Gissane’s angle (critical angle)^{[1][2][3][4][5][6]}: Is located directly through the inferior process to the lateral process of the talus bone and in normal healthy non-fractured calcaneal bone is ranged from 120° to 145°. The Gissane’s angle consisted of the downward and upward slopes of the calcaneal superior surface. The lateral plain film of the calcaneus and hindfoot gives the b est view of this angle.

These two angles are useful for the calcaneal fracture severity evaluations and the related surgical managements.
