Isolated navicular dislocations are unusual. They are frequently associated with navicular fractures or diverse patterns of lateral column injuries. We report a case of a patient with medial and plantar navicular dislocation with a comminuted intra-articular fracture of the anterior process of the calcaneus and associated subluxation at the calcaneocuboid joint. The patient underwent closed reduction and Kirschner wire stabilization in the Emergency Service. As part of the deferred treatment, talonavicular-cuneiform and calcaneocuboid 2.0 mm bridge plates were temporarily placed and osteosynthesis material was removed 5 months later. The AO-FAS score was excellent in the one-year follow-up. Conclusion: An accurate diagnosis, ruling out lateral column injuries, should be done in the Emergency Service. Bridge plate stabilization is a valid option to prevent loss of reduction, which is observed when removing Kirschner wires, allowing early weight-bearing.
