Wrist joint
- This joint is abbreviated as the RC (radiocarpal) joint. The proximal row of carpal bones (from the lateral side: scaphoid, lunate, triquetrum) and the inferior (distal) surface of the radius, that is, the carpal articular surface of the radius comprise the wrist joint. Note that the pisiform is not involved in the formation of this joint, even if it is the carpal bone of proximal row.
- This joint has a range of motion of 15° in abduction, 45° in adduction, 85° in flexion, and 85° in extension. Since this joint is classified as an condylar (ellipsoid) joint, it can be rotated in a circular motion (circumduction) by following the above four movements in sequence.
