What is the Second Metatarsal

The second metatarsal is the metatarsal bone located at the proximal end of the second proximal phalanx of the foot. It is associated with the second or index toe, being analogous to the second metacarpal in hand. This is the longest of all the five metatarsals.

Anatomy and Landmarks

It is a long bone divided into a head, body, and base.

Second Metatarsal


At its base, there are 4 articular facets for the three cuneiform bones and the third metatarsal.  These articulations create an arch that acts like a keystone for the tarsometatarsal joints (joints between the tarsals and metatarsals in the foot). The bone also articulates with the first metatarsal through a medial facet at its base.

On the distal side, it articulates with the second proximal phalanx.

Muscle Attachment

  • The first dorsal interosseus muscle attaches to the medial part of the body of the second metatarsal
  • The second dorsal interosseus muscle attaches to the lateral side of the body.
