Key Features & Anatomical Relations

The cuboid bone is one of the seven tarsal bones of the foot. It’s somewhat cube-shaped and is found in the distal row of tarsal bones. The cuboid bone is classified as a short bone and includes the following bony features:

- parts: tuberosity and calcaneal process;

- surfaces: dorsal, plantar, medial and lateral surfaces, and proximal and distal articular surfaces;

- landmarks: navicular, lateral cuneiform, fourth and fifth metatarsal articular facets.

More information regarding these bony features can be found in the Parts, Surfaces and Landmarks tabs for this bone.

The cuboid bone is located:

- proximal to the fourth and fifth metatarsal bones;

- distal to the calcaneus;

- lateral to the navicular and lateral cuneiform bones.

It articulates with the:

- fourth and fifth metatarsal bones, contributing to the formation of the tarsometatarsal joints;

- calcaneus at the calcaneocuboid joint;

- navicular bone at the cuboideonavicular joint;

- lateral cuneiform bone at the cuneocuboid joint.

The cuboid bone contributes to the formation of the lateral longitudinal arch of the foot.

Ossification

Ossification of the cuboid bone occurs at one ossification center, which appears just before birth (Standring, 2016).

Variations

In some individuals:

- the proximal articular surface may present in a different shape and size;

- an accessory ossicle, known as the os cuboides secundarium, may be associated with the cuboid bone (Standring, 2016).

Surface Anatomy

With regard to surface anatomy, the cuboid bone can be located by first identifying the tuberosity of fifth metatarsal bone, which can be palpated on the lateral aspect of the foot. The lateral surface of cuboid bone is then found in the depression located immediately proximal to this landmark.
