Cuneiform Bones

Cuneiforms are three wedge like bones in the tarsus. They articulate with the navicular proximally and the bases of first to third metatarsals distally. They are named as: Medial, Intermediate and Lateral.

The medial cuneiform is the largest while the intermediate is smallest. In the medial cuneiform the wedge is reversed, which forms the prime factor in maintaining the transverse arch of foot.

Medial Cuneiform articulates proximally with the navicular and distally with the base of first metatatrsal bone. For detailed study of medial cuneiform bone, visit the page: “Medial Cuneiform“.

Intermediate Cuneiform articulates proximally with the navicular and distally with the base of second metatarsal bone. For detailed study of intermediate cuneiform visit the page: “Intermediate Cuneiform“.

Lateral cuneiform articulates proximally with the navicular and distally with the base of third metatarsal bone. For detailed study of lateral cuneiform, visit the page: “Lateral Cuneiform“.
