Cuneiform bones

  • The three cuneiform bones (latin: ossa cuneiformia) are located between the navicular bone and the first three metatarsal bones, and medial to the cuboid bone.

    The three cuneiforms are named:

    • medial (first) cuneiform bone,
    • intermediate (middle, second) cuneiform bone,
    • lateral (third, external) cuneiform bone.

    Each cuneiform bone features four articular surfaces: posterior, anterior, lateral, and medial articular surfaces.

    The posterior articular surfaces of the cuneiform bones articulate with the navicular bone.

    The anterior articular surfaces articulate with the first, second, and third metatarsal bones.

    The lateral and medial articular surfaces articulate with each other and with the cuboid bone - as in the case of the lateral cuneiform.
