There are three cuneiforms in each foot that include:
1. Medial cuneiform
2. Intermediate cuneiform
3. Lateral cuneiform
The medial cuneiform is also known as the first or internal cuneiform. It is considered the largest among the three cuneiforms. This bone articulates with the scaphoid, first 2 metatarsal bones and intermediate cuneiform. It has a wedge-shaped appearance and is located at the middle side of the foot.
The intermediate cuneiform is also called the second or middle cuneiform. It is located between the medial and lateral cuneiforms. This bone articulates with the posteriorly with the navicular, anteriorly with second metatarsal and laterally with the two other cuneiforms. This bone makes the ankle and foot flexible, which allows bipedal movements such as walking.
The other names for the lateral cuneiform are third or external cuneiform. It is located at the outer side of the foot. In particular, the lateral cuneiform is found at the middle of the tarsals’ front row.It lies between the cudoid (laterally) and intermeidate cuneiform (medially). It is anterior to the navicular and posterior to the third metatarsal bone. This bone supports the body and is involve in motion.
