Type I: Dorsal or tuberosity Avulsion fracture, the primary fracture line traverse in the coronal plane, which is seen on a lateral radiograph. Type II: Navicular body fracture, in which the fracture line is traverse from dorsolateral to plantarmedial across the body, which is seen on an anteroposterior radiograph. Type III: Navicular body fracture with central or lateral comminution. Fig. 2. Sangeorzan's classification of navicular fracture.
