Cuboid Bone
The structure indicated is the
cuboid bone of the foot.
The foot contains
three groups of bones:
- Tarsals
- Metatarsals
- Phalanges
The
cuboid bone is one of seven tarsal bones. There are three groups of tarsal bones:
- Proximal group
- Intermediate group
- Distal group
The cuboid bone belongs to the distal group of tarsal bones. There are four bones in the distal group:
- Lateral cuneiform
- Intermediate cuneiform
- Medial cuneiform
- Cuboid
The
cuboid bone is the most
lateral bone in the distal row of tarsal bones, it is named on the basis of its shape which roughly resembles a cube. The plantar surface of the cuboid bone contains a
groove through which the tendon of the
peroneus longus travels from the lateral aspect of the foot to insert medially at the base of the first metatarsal and on the medial cuneiform bone. The
tibialis posterior muscle inserts onto the plantar surface of the cuboid bone.
