ABSTRACT
Calcaneal (os calcis) fractures account for 1% of all fractures and 75% of tarsal fractures. They occur most frequently in males of working age and often lead to significant socioeconomic problems. The calcaneus has a complex shape, articulating on four surfaces with the talus and cuboid. The calcaneus is important for weight-bearing, lever arm force transmission and foot shape, all of which may be altered by a fracture.
