Anatomical terminology


A saddle joint (sellar joint, articulation by reciprocal reception) is a type of synovial joint in which the opposing surfaces are reciprocally concave and convex.

Movements

The movements of saddle joints are similar to those of the condyloid joint and include flexion, extension, adduction, abduction, and circumduction but not axial rotation. Saddle joints are said to be biaxial, allowing movement in the sagittal and frontal planes.

Examples of saddle joints in the human body include the carpometacarpal joint of the thumb,[1][2] the sternoclavicular joint of the chest,[3] and the incudomalleolar joint of the inner ear.[4]
