Structure of Intermediate Cuneiform:

It consists of the following surfaces.

  • Plantar Surface: It is narrow and receives a slip from the tendon of tibialis posterior.
  • Distal and Proximal Surfaces: Both are triangular articular facets. The proximal surface articulates with navicular while the distal surface articulates with the base of second metatarsal bone.
  • Medial Surface: It is partly articular, joining with the medial cuneiform.
  • Lateral Surface: It is also partly articular, joining with the lateral cuneiform.

Blood supply of intermediate cuneiform:

The intermediate cuneiform is supplied via its dorsal, medial and lateral surfaces, mainly from the dorsal arterial network.

Nerve supply to intermediate cuneiform:

The intermediate cuneiform is innervated by the deep peroneal and medial plantar nerves.

Ossification of intermediate cuneiform:

The ossification center of the intermediate cuneiform appears during the third year of life.
