The intraarticular fracture of distal end of radius have bad returns more than extra articular fractures whereform the range of motion in flexion and extension, radial variance and ulnar variance of the joint. Shortness of the radius and the directio
n of articular surface of the radius should be corrected. The integrity of radial articular surface play an important rule in determining results. Displacement of the articular surface more than 1 mm cause an obstinate pain and synarthrophysis thereafter. More than 92% of the patients with disalignment of articular surfaces with space more than 2 mm end with arthrosis in the radial carpal joint. Through examening patients with union with shortness of radius more than 2 mm, we notices recuction of the wrist range of motion ) flextion-extention- pronation -supination) more than patients without shortness. Also we couldnt find sufficient statitics about the pain during motion.
