Cuboid bone
|
|
The cuboid bone is one of seven Tarsal bones. Distally, the Cuboid articulates with the fourth and fifth metatarsals, forming the fourth and fifth tarsometatarsal joints. Proximally, it articulates with the calcaneus, forming the calcaneocuboid joint. The medial surface of the bone articulates with both the lateral cuneiform bone and the navicular bone.
The inferior surface has a groove on it's distal third for the tendon of the peroneous longus muscle.
