Condyloid joint
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 flexion, extension, adduction, abduction, and circumduction.
==Examples==
Examples include:〔(Module - Introduction to Joints )〕
* the wrist-joint
* metacarpophalangeal joints
* metatarsophalangeal joints
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.
