Cuneiform bones by Anatomy.app. Each cuneiform bone articulates with each other and the adjacent bones, and all of them present four articular surfaces: Posterior articular surface. Anterior articular surface.
The cuneiform bones form a unique series of bone tightly bound together and function as a unit. They articulate with the navicular proximally through three separate facets and with metatarsal segments distally. Laterally, the third cuneiform articulates with the wedge like medial third of the cuboid.
The triquetral bone ( / traɪˈkwɛtrəl, - ˈkwiː -/; also called triquetrum, pyramidal, three-faced, and formerly cuneiform bone) is located in the wrist on the medial side of the proximal row of the carpus between the lunate and pisiform bones. It is on the ulnar side of the hand, but does not directly articulate with the ulna.
