Dec 20, 2023 · The proximal interphalangeal joint (PIPJ) refers to the articulation between the proximal and middle phalanx in the hand. It is present in all digits except the thumb. It is a synovial hinge joint which permits flexion and extension in center of the fingers, contributing to fine motor control. In this article, we shall look at the anatomy of ...

The thumb got one interphalangeal joint as mentioned at the end of the article. Maybe the metacarpophalangeal joint of the thumb should not be mentioned in the article, though. Cheers / Mats Halldin 11:06, 29 July 2006 (UTC) Reply More clear, I hope: The bones of the fingers and toes are the only human bones called phalanges. So, yes, these ...
The interphalangeal joints of the foot (Latin: articulationes interphalangeae pedis) are synovial hinge type articulations located in the foot. These joints are formed between the phalanges of the toes. Articulating structures. Within each interphalangeal joint articulates: Base of the phalanx; Head of the phalanx . Joint capsule and ligaments
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 ...
Locking of the metacarpophalangeal joints is well documented, but locking of other joints in the finger has not been described. We present a case of locking of the little finger proximal interphalangeal joint due to an osteophyte impinging on the extensor tendon.
Closed pack position: the position where there is the most congruency of the joint surfaces. In this position, joint stability increases. The closed pack position for interphalangeal joints is at full extension. Degrees of freedom: the direction of joint movement or rotation; there is a maximum of six, including three translations and three ...
