A condyloid joint (also called condylar, ellipsoidal, or bicondylar[1]) is an ovoid articular surface, or condyle that is received into an elliptical cavity. This permits movement in two planes, allowing flexion, extension, adduction, abduction, and circumduction.

Examples

Examples include:[2]

These are also called happy joints. Oval shaped condyle of one bone fits into elliptical cavity of other bone. These joints allow biaxial movements i.e. forward-backward and side to side but not rotation. Radiocarpal joint and Metacarpo-phalangeal joint are examples of condyloid joint.

An example of a Ball and socket joint is the Elbow Joint. A ball and socket joint works exactly as a ball and socket. An example of a Ellipsoid joint is the wrist; it is exactly like the ball and socket joint except you cannot move it 360 degrees like the ball and socket.
