The interphalangeal articulations of the foot are the joints between the phalanges of the toes. They are ginglymoid (hinge) joints, and each has a plantar and two collateral ligaments. In the arrangement of these ligaments, extensor tendons supply the places of dorsal ligaments, which is similar to that in the metatarsophalangeal articulations.


The only movements permitted in the joints of the digits are flexion and extension; these movements are more extensive between the first and second phalanges than between the second and third. The amount of flexion is very considerable, but extension is limited by the plantar and collateral ligaments.
