Movements
The movements are a the same as in a condyloid joint; that is to say, flexion, extension, adduction, abduction, and circumduction are allowed; but no axial rotation. Saddle joints are said to be biaxial, allowing movement in the sagittal and frontal planes.
Examples
The best example of this form is the carpometacarpal joint of the thumb.[1]
