Fracture of the anterior calcaneal process is an uncommon type of extra-articular calcaneal fracture. It is best depicted on oblique radiograph and can be occult on AP and lateral radiograph. Therefore a cross-sectional imaging study (CT/MR) is useful for detecting this type of fracture.
A small, non-displaced fracture, which involves less than 25% of calcaneocuboid articular surface, like in this case, is treated conservatively (protective weight bearing).
