【Abstract】 By means of X- ray measurement and STK video analysing system,the maximum amplitude of motion on metacarpal flexion,adduction,abduction of articulatio radiocapea, length and actuating arm of each muscle at movement were measured and analysed. The authors pointed out the external features aud internal mechanism of the movement of articulatio radiocapea.更多还原
