Abstract: Radial and Ulnar deviation indicates distal radioulnar joint flexibility. It also is a reflection of the structure and function of the carpal bones, ulnar, radius and surrounding ligaments. The radioulnar carpal joint is very important for hand and wrist functions. This study evaluated the radial and ulnar deviation movements at the wrist at the wrist to ascertain if the range of these movements were affected by gender, handedness, and a post-traumatic wrist in young adult males and females residing in Rivers State.
