Circumduction

Circumduction is a combination of flexion, extension, abduction and adduction
The shoulder, hip, wrist and ankle are all examples of joints which can circumduct, because circumduction movements of (e.g. the arm and hand) result in the outer edge of the limb (e.g. the finger tips) tracing circles in space. Another way to express this is to say that circumduction is the movement of the distal end of a body part so that it traces a circle.

However, circumduction is more accurately described as a conical movement at a joint due to the cone formed by the rotating limb (i.e. the distal end of the limb traces a circle while the movement of the length of the limb traces a cone shape).
