Interphalangeal articulations of hand

The interphalangeal articulations of the hand are the hinge joints between the phalanges of the hand (i.e. the finger bones).

There are two sets (except in the thumb):

Anatomically, the proximal and distal interphalangeal articulations are very similar. There are some minor differences in how the volar plates are attached proximally and in the segmentation of the flexor tendon sheath, but the major differences are the smaller dimension and reduced mobility of the distal joint.
