There are three cuneiform ("wedge-shaped") bones in the human foot:
- the first or medial cuneiform
- the second or intermediate cuneiform, also known as the middle cuneiform
- the third or lateral cuneiform
They are located between the navicular bone and the first, second and third metatarsal bones and are medial to the cuboid bone.
Structure
There are three cuneiform bones:
- The medial cuneiform (also known as first cuneiform) is the largest of the cuneiforms. It is situated at the medial side of the foot, anterior to the navicular bone and posterior to the base of the first metatarsal. Lateral to it is the intermediate cuneiform. It articulates with four bones: the navicular, second cuneiform, and first and second metatarsals. The tibialis anterior and fibularis longus muscle inserts at the medial cuneiform bone.

- Cuneiform fracture - Due to the ligamentous support of the midfoot, isolated cuneiform fractures are rare
