The interphalangeal joints of the hand are the hinge joints between the phalanges of the fingers that provide flexion towards the palm of the hand. There are two sets in each finger: "proximal interphalangeal joints", those between the first and second phalanges "distal interphalangeal joints", those between the second and third phalanges Anatomically, the proximal and distal interphalangeal joints are very similar. There are some minor differences in how the palmar plates are attached proximall

The PIP joint exhibits great lateral stability. Its transverse diameter is greater than its antero-posterior diameter and its thick collateral ligaments are tight in all positions during flexion, contrary to those in the metacarpophalangeal joint.
The only movements permitted in the interphalangeal joints are flexion and extension. 1. Flexion is more extensive, about 100°, in the PIP joints and slightly more restricted, about 80°, in the DIP joints. 2. Extension is limited by the volar and collateral ligaments. The muscles generating these movements are: The relative length of the digit varies during motion of the IP joints. The length of the palmar aspect decreases during flexion while the dorsal aspect increases by about 24 mm. The useful range of motion of the PIP joint is 30–70°, increasing from the index finger to the little finger. During maximum flexion the base of the middle phalanx is firmly pressed into the retrocondylar recess of the proximal phalanx, which provides maximum stability to the joint. The stability of the PIP joint is dependent of the tendons passing around it.
Rheumatoid arthritis generally spares the distal interphalangeal joints. Therefore, arthritis of the distal interphalangeal joints strongly suggests the presence of osteoarthritis or psoriatic arthritis.

The carpometacarpal joint connects the carpal bones to the metacarpus or metacarpal bones which are joined at the intermetacarpal articulations. In the fingers, finally, are the metacarpophalangeal joints (including the knuckles ) between the metacarpal bones and the phalanges or finger bones which are interconnected by the interphalangeal joints .
This should be uncontroversial, unless the phrase "interphalangeal articulations of hand" is known to be the accepted term. I don't know much about anatomical terminology. :) Same thing goes for Interphalangeal articulations of foot. — Quuxplusone 17:13, 21 May 2009 (UTC) Survey

In the human hand, palmar or volar plates are found in the metacarpophalangeal and interphalangeal joints, where they reinforce the joint capsules, enhance joint stability, and limit hyperextension. The plates of the MCP and IP joints are structurally and functionally similar, except that in the MCP joints they are interconnected by a deep transverse ligament. In the MCP joints, they also indirectly provide stability to the longitudinal palmar arches of the hand. The volar plate of the thumb MCP
