Functional Anatomy of the Wrist - Physiopedia
The wrist includes three joints: the distal radioulnar joint, the radiocarpal joint and the midcarpal joint. The movements at the wrist are flexion and extension, radial and ulnar deviation and pronation and supination (at the distal radioulnar joint). Optimal wrist function requires adequate range of motion.
