Glossary Term
Saddle Joint
A sellar joint, also known as a saddle joint or articulation by reciprocal reception, is a type of synovial joint where the opposing surfaces are reciprocally concave-convex, allowing for motion in two planes. This type of joint is similar to how a horseback rider can move in a saddle. Examples of sellar joints in the human body include the trapeziometacarpal joint of the thumb (1st carpometacarpal joint) and the sternoclavicular joint. Synonyms include sellar and sellar joint.
