Objective : To investigate the3D motion range of talonavicular joint and its roles in the motion of foot .

目的：探讨 距 舟关节的三维运动范围及其在足运动中的作用。

Objective To discuss the effect of the calcaneocuboid arthrodesis on three-dimensional kinematics of talonavicular joint and its clinical significance .

目的探讨跟骰关节融合对 距 舟关节三维运动度的影响及其临床意义。

Results A significant decrease in the three-dimensional kinematics of talonavicular joint was observed ( P < 0.01 ) in cadaver model following calcaneocuboid arthrodesis .

结果跟骰关节融合后， 距 舟关节三维运动 度较融合 前明显减小（P<0.01）；

The von Mises stress and distribution scope were difference in different phase . The von Mises stress in the talar dome talar neck talonavicular joint surface gradually increased and decreased in the subtalar joint . 3 .

不同 位相距骨VONMISES应力值及分布范围不同，等效应力在距骨滑车、距骨颈及 距 舟关节 从 落地 相到 离地相逐渐增大，在距下关节逐渐减小。
