The navicular bone is a boat-shaped tarsal bone located on the medial side of the midfoot, between the talus and the cuneiform bones. It serves as a key structural component of the medial longitudinal arch, distributing weight and maintaining foot stability during movement. Clinically, it is significant as a common site for stress fractures and accessory navicular syndrome, both of which can cause medial foot pain and impaired mobility.
