Bones of the Foot

5. Cuneiforms

There are three cuneiform bones in the foot: the medial, intermediate, and lateral. Some individuals refer to these bones as the first, second, and third cuneiforms, respectively. The medial cuneiform is the largest and forms a joint with the intermediate cuneiform and the first two metatarsals. The intermediate cuneiform has a wedge-like shape and articulates with both of the other cuneiforms and the second metatarsal. Like the intermediate cuneiform, the lateral cuneiform is also wedge-shaped. It meets the cuboid, intermediate cuneiform, and the third metatarsal. All three cuneiforms form joints with the navicular.
