In a saddle joint (sellar joint, articulation by reciprocal reception) the opposing surfaces are reciprocally concave-convex.
Contents |
Movements
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.
Examples
The best example of this form is the carpometacarpal joint of the thumb.[1]
