The interphalangeal articulations of the foot (articulations of the phalanges) are ginglymoid joints, and each has a plantar and two collateral ligaments. The arrangement of these ligaments is similar to that in the metatarsophalangeal articulations: the Extensor tendons supply the places of dorsal ligaments.
