Description. Interphalangeal joints of hand (green) 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. [1] Anatomy. There are two sets in each finger (except in the thumb, which has only one joint)
Nov 9, 2023 · Reading time: 4 minutes. The proximal interphalangeal (PIP) joints of the fingers are extremely important for gripping things with hands, more specifically, what is called the ‘power’ grip. Being a hinge joint, the joint’s articular surface and soft tissue do not permit any lateral movement.
A complete understanding of the normal anatomy and biomechanics of the proximal interphalangeal joint is critical when treating pathology of the joint as well as in the design of new reconstructive treatments. The osseous anatomy dictates the principles of motion at the proximal interphalangeal joint. Subsequently, the joint is stabilized throughout its motion by the surrounding proximal ...

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 .
Oct 21, 2010 · A large, population-based study demonstrated OA to be more common in elderly women than in men, 67% vs 54.8%, with at least one proximal interphalangeal (PIP) joint being affected in 18.2% of individuals with OA. Proximal interphalangeal joint arthritis was the second leading cause for hand pain behind the thumb carpometacarpal (CMC) joint.
