Medial cuneiform to second metatarsal distance is an important measurement used in assessing the integrity of the midfoot and is increased in Lisfranc/tarsometatarsal injuries 2,3.
Medial cuneiform to second metatarsal distance is measured on the DP (dorsoplantar) foot radiographs. It is measured by the distance between the lateral aspect of the medial cuneiform and the medial aspect of the base of the second metatarsal bone 1,2.
- normal values 1,2
- <2-2.5 mm on dorsoplantar foot radiographs
- the medial cuneiform to second metatarsal distance can vary in pediatric patients and approaches the normal adult values after 6 years of age 2
- before 6 years, it can vary from 3 to 7.5 mm 2
