Function
The bone is a part of the longitudinal arch of the foot and hence plays a role in even distribution of the weight through the bones in the foot.
Disease/ Injury/ Fracture
Blunt trauma caused from heavy objects rolling onto the top of the foot may cause fracture of the bone. It is particularly common as an injury site in athletes.
Interesting fact
The name navicular is derived from the boat-like shape of the bone. It has a highly concave articular surface which makes the bone appear like a small boat.
