Bones of the Foot

6. Metatarsus

The metatarsal bones, or metatarsus, are a group of five bones that sit between the phalanges of the toes and the cuneiforms. Unlike other bones, the metatarsals do not possess individual names. Instead, each bone has a number from one to five, beginning at the inside of the foot. Each metatarsal bone tapers gradually from the extremity.

• The first metatarsal articulates primarily with the medial cuneiform, though it can slightly articulate with the intermediate cuneiform as well.
• The second metatarsal articulates with every cuneiform.
• The third articulates with the lateral cuneiform.
• The fourth articulates with the lateral cuneiform and the cuboid.
• The fifth metatarsal articulates exclusively with the cuboid.
