The intermediate cuneiform (second cuneiform or middle cuneiform) is shaped like a wedge, the thin end pointing downwards. The intermediate cuneiform is situated between the other two cuneiform bones (the medial and lateral cuneiforms), and articulates with the navicular posteriorly, the second metatarsal anteriorly and with the other cuneiforms on either side.
The lateral cuneiform (also known as third cuneiform or external cuneiform) intermediate in size between the other two cuneiform bones, is also wedge-shaped, the base being uppermost. It occupies the center of the front row of the tarsal bones, between the intermediate cuneiform medially, the cuboid laterally, the navicular posteriorly and the thirdmetatarsal in front. The tibialis posterior inserts at the medial cuneiform, while the flexor hallucis brevis originates from it.
