In a saddle joint (sellar joint, articulation by reciprocal reception) the opposing surfaces are reciprocally concave-convex.

The movements are the same as in a condyloid joint; that is to say, flexion, extension, adduction, abduction, and circumduction are allowed; but no axial rotation.

The best example of this form is the carpometacarpal joint of the thumb.
