Medial cuneiform-fifth metatarsal height is the distance between the most inferior part of the medial cuneiform and the most inferior part of the base of the 5th metatarsal and is used to evaluate the height and integrity of the medial vertical arch 1.
Medial cuneiform-fifth metatarsal height is an important measurement used in the assessment of the integrity and height of the arch. It is considered a reliable parameter for the evaluation of pes planus and pes cavus 2.
Medial cuneiform-fifth metatarsal height is measured on the lateral weight-bearing foot radiographs. It is measured by the distance between two parallel lines drawn from the most inferior part of the medial cuneiform and the most inferior part of the base of the 5th metatarsal 1-4.
