The intermediate cuneiform is one of the tarsal bones located between the medial and lateral cuneiform bones.

Gross anatomy
Osteology
This is a wedge-shaped small bone in the distal tarsal row. Its distal and proximal surfaces are triangular and articulate with the navicular bone and base of second metatarsal. The medial and lateral surfaces are partly articular and are appositional to the medial and lateral cuneiforms respectively. The plantar surface is narrow and receives a slip of the tibialis posterior.
Articulations
It articulates with the navicular bone proximally and the base of the second metatarsal bone distally. Medially and laterally its articulations with medial and lateral cuneiform are present.
Attachments
Musculotendinous
A tendon slip of tibialis posterior attaches to the plantar surface.
Ligamentous
Strong but small interosseous ligaments connect the non-articular surfaces to adjacent cuneiforms.
Arterial supply
This cuneiform is supplied by branches of the dorsal arterial network to its dorsal, medial and lateral surfaces.
Innervation
The intermediate cuneiform is innervated by the deep peroneal and medial plantar nerves, same as the medial cuneiform.
Development
Ossification
Single ossification center which arises at the third year of life.
