Intermediate cuneiform articulates proximally with the navicular and distally with the base of second metatarsal bone.
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.
