Interphalangeal joints of the hand are the hinge joints located between the phalanges of the human hand. The interphalangeal joints are all hinge joints, a type of synovial joint that allows motion in one plane only.
Etymology
The term "interphalangeal" comes from "inter-", a prefix meaning "between", and "phalangeal", which pertains to the phalanges (the bones of the fingers and toes).
Anatomy
The interphalangeal joints of the hand are divided into two categories: the proximal interphalangeal joints (PIPs) and the distal interphalangeal joints (DIPs). The PIPs are the joints in the middle knuckles of the fingers, while the DIPs are the joints closest to the end of the fingers.
Each interphalangeal joint is surrounded by a joint capsule, and the bones that form the joint are covered by articular cartilage.
Function
The interphalangeal joints of the hand allow for flexion and extension of the fingers, which is essential for many tasks involving the hands.
Clinical significance
Conditions that can affect the interphalangeal joints of the hand include osteoarthritis, rheumatoid arthritis, and psoriatic arthritis. These conditions can cause pain, stiffness, and reduced function in the joints.
