Learn about the interphalangeal joints of the hand, also known as PIP joints, which are synovial hinge joints that permit fine motor movements in the digits. Find out their articular surfaces, ligaments, innervation, blood supply, and movements.
Learn about the anatomy, structure and movements of the hinge joints between the phalanges of the fingers. The web page explains the differences between the proximal and distal interphalangeal joints, the ligaments, tendons and muscles involved, and the range of motion and stability of each joint.
Learn about the anatomy, function and pathology of the interphalangeal joints of the hand, which are the hinge joints between the phalanges of the fingers. Find out how they enable flexion and extension movements and what muscles act on them.
Interphalangeal Joint (IP) The thumb digit has only two phalanges (bones) so it only has one joint. The thumb interphalangeal (IP) joint is similar to the distal interphalangeal (DIP) joint in the fingers. The IP joint in thumb is located at the tip of the finger just before the fingernail starts.
Learn about the structure and function of the PIP joints, which are important for gripping and flexing the fingers. Find out how they are formed, stabilized and moved by hard and soft tissue, and what clinical problems can affect them.
Interphalangeal joint arthritis is arthritis of the fingers, affecting the joints between the bones of each finger. Learn about the causes, symptoms and treatment options, including surgery, from the Penn Integrated Hand Program experts.
Learn about the structure and function of the phalanges of the hand, the small bones that form the fingers. Find out how the interphalangeal joints connect the proximal, middle and distal phalanges and enable various movements.
Learn about the proximal interphalangeal joint (PIPJ), a synovial hinge joint in the hand that allows flexion and extension of the fingers. Find out its structure, ligaments, movements, blood supply, innervation, and clinical relevance.
Interphalangeal joint (IP): This joint, the only one in your thumb, is at the base of the thumbnail and connects its two phalanges. The thumb offers unique features that your other digits don't. First, the tip of the thumb can touch all the fingers of the same hand.
Learn about the anatomy, movements and muscles of the interphalangeal joints of hand, which are hinge-joints with volar and collateral ligaments. See diagrams and references from IMAIOS, a medical image database.
