* Movement - flexion and extension.
* The joint capsule attaches near the articular surfaces of the proximal and middle phalanges. It extends slightly in a pouch dorsally and more extensively on the palmar aspect. The dorsal capsule is reinforced by a fibrocartilaginous nodule; the extensor tendon attaches to the capsule here.
* '''Collateral ligaments''' - connect the distal end of the proximal phalanx to the proximal end of the middle phalanx. They lie in a vertical direction rather than along the bone axis.
