The Gissane angle angle (also,also known as the "critical angle"), is an angular measurementmeasurement made directly inferior to the lateral process of the talus. It is formed by the downward and upward slopes of the calcaneal superior surface. It is better seen on a lateral plain film of the calcaneus and hindfoot. Its normal value is usually between 95° and 105.
Gissane’s angle, with thetogether with BohlerBöhler’s oneangle, are commonly used to evaluate the severity of a calcaneal fracture and the goal of a surgical treatment is to restore these angles to normal values.
