Anatomical terminology

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


The movements are as same as in the 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.


The best example of saddle joints are first carpo metacarpal joints (Articulationes carpometacarpeae), joints between femur and patella, calcaneocuboid joints.
