Ankle and foot

Intermediate cuneiform

Os cuneiforme intermedium

How to find it
Lies between its two neighbours, proximal to the second metatarsal. It projects less far distally than they do, creating a recess into which that ray is set.
What you use it for
That recess makes the second metatarsal the keystone of the transverse arch. It is exactly there that the midfoot fails in a Lisfranc injury.
