The relative contribution of the scaphoid, lunate, triquetrum, and capitate to wrist motion was examined in 6 fresh cadaver forearms. A wrist-joint motion simulator was used to dynamically move each wrist through planar and nonplanar motions. During wrist flexion-extension, the motion of the capitate closely followed the motion of the third metacarpal, while the lunate motion was approximately 50% of the total motion; the triquetrum, 65%, and the scaphoid, 90%. Similar differences in motion for… CONTINUE READING
