Navicular Fracture

Abstract

The tarsal navicular is an essential component of the Chopart joint and crucial for most of hindfoot motion. Most fractures are low-energy dorsal avulsions that may be treated nonoperatively. Displaced comminuted fractures require open reduction and internal fixation, sometimes with external fixation, bridge plating, and bone grafting. Diagnosis of stress fractures is commonly delayed. Conservative treatment is associated with good results, but surgery allows for quicker return-to-play in athletes. Nonunion in acute and stress fractures needs open debridement, grafting, and stable fixation. Müller-Weiss disease may present with a fragmented navicular and mimic an acute or a stress fracture.
