 | | The wrist includes 5 large joint cavities in addition to the intercarpal joint spaces: the radiocarpal joint, the distal radio-ulnar joint (DRUJ), the midcarpal joint, the large carpometacarpal joint (between the carpus and the second, third, fourth, and fifth metacarpals), and the small carpometacarpal joint (between the first metacarpal and the trapezium). |
 | | Movement of the wrist is 80° in flexion, 70° in extension, 30° in ulnar deviation, and 20° in radial deviation. |
 | | Pronation and supination occur at the radial-ulnar articulation in the forearm, not at the wrist. |
