Lateral cuneiform bone

  • The lateral cuneiform bone (also known as third cuneiform or external cuneiform, latin: os cuneiforme laterale) is medium sized compared to the other two cuneiforms.

    The lateral cuneiform articulates with four bones: the intermediate cuneiform, cuboid, navicular, and the third metatarsal bone.

    Two muscles attach to the lateral cuneiform bone: the tibialis posterior inserts at the lateral cuneiform bone, while the flexor hallucis brevis originates from it.
