PIP: proximal interphalangeal joint between the proximal and middle phalanges; DIP: distal interphalangeal joints between the middle and distal phalanges; The function of the interphalangeal joints of the hand is to permit fine motor movements in the digits, including flexion towards the palm.
May 26, 2022 · Anatomically, the proximal and distal interphalangeal joints are very similar. There are some minor differences in how the palmar 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.

Anatomical terminology. [ edit on Wikidata] The intermetacarpal joints are in the hand formed between the metacarpal bones. The bases of the second, third, fourth and fifth metacarpal bones articulate with one another by small surfaces covered with cartilage. The metacarpal bones are connected together by dorsal, palmar, and interosseous ligaments.
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 ...
Joints. The joints in our hands are made up of cartilage surfaces that cap the bones. Cartilage is a smooth surface that allows for gliding. When cartilage is healthy, there is a cushioning effect of the cartilage that absorbs and evens out the forces across the joint. Our joints typically have a capsule of tough, but flexible, fibrous tissue ...
