Os intercuneiforme

Last revised by Dr Yahya Baba on 25 Oct 2021

An os intercuneiforme is a supernumerary tarsal bone located between the first and second cuneiforms, anterior to the navicular bone

It's a rare ossicle with an estimated prevalence of 1-2% 1

It's a triangular-shaped bone appearing to be an isolated proximal corner of the medial cuneiform. 

It is thought to belong rather to the medial than to the intermediate cuneiform 2.

Some authors claim that with its rare occurrence and small dimensions, this bone is not expected to be of any clinical significance 2.
