The cuboid bone is one of the seven tarsal bones located in the foot. It is situated on the outer side of the foot, between the calcaneus (heel bone) and the fourth and fifth metatarsal bones. The cuboid bone plays a crucial role in maintaining the stability and structure of the foot, particularly in the area that supports weight during walking and running. This bone has a cube-like shape, which is where it gets its name. It helps form the lateral arch of the foot and provides attachment points for several ligaments and tendons, contributing to the overall function and movement of the ankle and foot.
