Wrist

Wrist joint: as the joint connecting hand to the forearm, wrist is the key to hand function and its positioning in space. It is a biaxial synovial joint. The concave distal radial ellipsoid articular surface articulates with convex proximal carpal row. It has a short radius for flexion/extension antero-posteriorly and long radius transversely for ABduction/ADduction. These movements are accompanied by movement at the intercarpal joints. 60% of wrist flexion and 40% of extension occurs at the metacarpal joint. Rotation is not allowed because of two different curvatures at right angles to each other. Physiologically, isolated movements do not occur. Wrist extension is accompanied by a degree of ADduction and flexion by ABduction.
