Fleck sign (foot)

Last revised by Leonardo Lustosa on 6 Mar 2022

The fleck sign in the foot is a small bony fragment seen in the Lisfranc space (between the base of the 1st and 2nd metatarsal) associated with avulsion of the Lisfranc ligament (at the base of the 2nd metatarsal or the medial cuneiform). It is a very subtle, but important finding since it predisposes to Lisfranc injury.
