The cuboid is one of the seven bones which make up the tarsus of the [[Ankle and Foot]] and it is one of the five bones of the mid-foot. It is located on the lateral aspect of the foot, anterior to the calcaneus, next to the navicular and lateral cuneiform bones, and posterior to the 4th and 5th metatarsal. <ref name=”:0″>Soames RW.

It is a small, irregular-shaped bone, approximately cubical in shape where is derives its name. The small bone contains many smooth facets to allow articulation with the calcaneus posteriorly, the [[Cuneiforms|cuneiform]] and [[navicular]] medially and the 4th and 5th [[metatarsals]] anteriorly. On the inferior aspect of the bone, there is a small bony prominence named the cuboid tuberosity and a sulcus stretching obliquely in an anteromedial direction called the peroneal sulcus, holding in place the tendon of the [[Peroneus (Fibularis) Longus Muscle|peroneus longus]]. Its shape and location mean that it plays a strong role in maintaining the lateral longitudinal arch of the foot, in addition to some of the role of the transverse arch along with the cuneiform bones.

The cuboid helps provide for the stability of the foot and the movement of the toes, in addition to ensuring proper weight distribution and flexibility along the plantar fascia that runs along the sole of the foot.

The cuboid is one of the seven bones which make up the tarsus of the Ankle and Foot and it is one of the five bones of the mid-foot. It is located on the lateral aspect of the foot, anterior to the calcaneus, next to the navicular and lateral cuneiform bones, and posterior to the 4th and 5th metatarsal. [1]

Muscle and ligamentous attachments[edit | edit source]

The only muscular attachment to the cuboid bone is a plantar branch of the tibialis posterior [5]

For its size, there are numerous ligaments that attach to the cuboid due to its role in direct weight-bearing. These are…

  • Dorsal and Plantar Calcaneocuboid ligaments
  • Birfurcate ligament (calcaneocuboid portion)
  • Cuboideonavicular ligament
  • Dorsal, plantar interosseous cuneocuboid ligaments

Fractures of the bone on its own are rare and so if fractures do occur, these are often alongside more widespread trauma [6]. Damage to the area of the cuboid is noted to be involved with a Lisfranc injury where the metatarsal bones are displaced from the tarsus [7]. The main related pathology is Cuboid Syndrome [8]
