A condyloid joint (also called condylar, ellipsoidal, or bicondylar
) is an
ovoid articular surface, or
condyle that is received into an elliptical cavity. This permits movement in two planes, allowing

Examples
Examples include:

*
metacarpophalangeal joints
*
metatarsophalangeal joints
*
atlanto-occipital joints
These are also called ellipsoid joints. The oval-shaped condyle of one bone fits into the elliptical cavity of the other bone. These joints allow
biaxial movements — i.e., forward and backward, or from side to side, but not rotation. Radiocarpal joint and
metacarpophalangeal joint are examples of condyloid joints.
An example of an Ellipsoid joint is the wrist; it functions similarly to the
ball and socket joint
The ball-and-socket joint (or spheroid joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. The distal bone is capable of motion around an indefinite number of ...
