A joint that allows movement in only one plane, such as a door hinge.
A joint in which a convexity on one bone fits into a corresponding concavity on another bone allowing motion in one plane only.
Freely movable (synovial) joint in which bones are articulated in such a way as to permit extensive motion in one plane. The elbow, knee, and interphalangeall joints are hinge joints.
A synovial joint in which two bones flex and extend in only one plane, usually because side (collateral) ligaments limit the direction of motion, e.g., elbow joint.
A hinge joint is a kind of movable connection that permits motion only in one direction – forward and backward. The knee and elbow joints are typical examples of hinge joints.
