Radial Deviation: Synonymous with wrist abduction. Also sometime called radial extension. Movement of the wrist which occurs in the fontal (coronal) plane, through the capitate of the wrist and at a right angle to the palm. The opposite of this movement is ulnar deviation or wrist adduction. Together the movements are that of using a hammer or waving. There is more motion in ulnar deviation than in radial deviation since the radial styloid's process contact with the scaphoid in radial deviation produces a hard end feel to this movement. See image below.
