Anatomical terminology] |
A condyloid joint (also called condylar, ellipsoidal, or bicondylarcircumduction.
Examples
Examples include:[2]
- the wrist-joint
- 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[3] — 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
except is unable to rotate 360 degrees; it prohibits axial rotation.
