There are two sets in each finger (except in the thumb, which has only one joint): "proximal interphalangeal joints" (PIJ or PIP), those between the first (also called proximal) and second (intermediate) phalanges "distal interphalangeal joints" (DIJ or DIP), those between the second (intermediate) and third (distal) phalanges

2023年10月30日 · The interphalangeal joints of the hand are synovial hinge joints that span between the proximal, middle, and distal phalanges of the hand. In digits 2-5 these joints can be further classified based on which bones are involved.

Metacarpophalangeal Joint (MCP Joint) The MP joint is where the hand bone, called the metacarpal, meets the finger bones called the phalanges. A single hand bone is called a phalanx.

2017年10月26日 · Metacarpophalangeal Joint (MCP): The MP joint is where the hand bone meets the finger bone, referred to as the “knuckle.” These joints are very important, allowing us to bend/flex and spread our fingers.

Proximal Interphalangeal Joint Pain is the most commonly injured joints of the hand. Find out more about PIP, its causes, treatment and more.

The PIP joint is a hinge joint that is normally kept in alignment by a soft tissue envelope consisting of joint capsule, the volar plate, collateral ligaments and the central slip. These structures form a tight-fitting ‘box’ with a very narrow joint space.

2021年11月16日 · Interphalangeal (IP) joints of the hand are hinge-type synovial joints between adjacent phalanges. The thumb has a single interphalangeal joint, and the second to fifth digits each have a proximal and a distal interphalangeal joint.

2023年11月9日 · 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.

2024年10月28日 · 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 …

Various complications are possible after treatment for a PIP joint injury. Although joint stiffness and flexion contracture are most common, other complications include re-dislocation, posttraumatic arthritis, chronic swelling, or even permanent functional loss.
