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

Break down the words in the name, metacarpophalangeal, and you get metacarpo-(hand bone) and phalangeal (finger bone). This joint moves a lot in some people and just a little in other people.

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.

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 …

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.

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.

2024年10月2日 · Metacarpophalangeal (MCP) Joint arthritis typically presents with pain, swelling, and limited motion. Inflammatory etiology is much more common than osteoarthritis
