To discuss the effect of the calcaneocuboid arthrodesis on three-dimensional kinematics of talonavicular joint and its clinical significance.
Ten fresh-frozen foot specimens, three-dimensional kinematics of talonavicular joint were determined in the case of neutral position, dorsiflexion. plantoflexion, adduction, abduction, inversion and eversion motion by means of three-dimensional coordinate instrument (Immersion MicroScribe G2X) before and after calcaneocuboid arthrodesis under non-weight with moment of couple, bending moment, equilibrium dynamic loading. Calcaneocuboid arthrodesis was performed on these feet in neutral position and the lateral column of normal length.
A significant decrease in the three-dimensional kinematics of talonavicular joint was observed (P < 0.01) in cadaver model following calcaneocuboid arthrodesis. Talonavicular joint motion was diminished by 31.21% +/- 6.08% in sagittal plane; by 51.46% +/- 7.91% in coronal plane; by 36.98% +/- 4.12% in transverse plane; and averagely by 41.25% +/- 6.02%.
Calcancocuboid arthrodesis could limite motion of the talonavicular joints, and the disadvantage of calcaneocuboid arthrodesis shouldn't be neglected.
探讨跟骰关节融合术对距舟关节三维运动学的影响及其临床意义。
10例新鲜冷冻足标本，在非负重、有耦合力矩、弯矩、平衡动态负荷情况下，于跟骰关节融合术前、后，通过三维坐标仪（Immersion MicroScribe G2X）测定距舟关节在中立位、背屈、跖屈、内收、外展、内翻和外翻运动时的三维运动学。在这些足处于中立位且外侧柱长度正常的情况下进行跟骰关节融合术。
在尸体模型中，跟骰关节融合术后距舟关节的三维运动学显著降低（P<0.01）。距舟关节运动在矢状面减少31.21%±6.08%；在冠状面减少51.46%±7.91%；在横断面减少36.98%±4.12%；平均减少41.25%±6.02%。
跟骰关节融合术可限制距舟关节的运动，跟骰关节融合术的弊端不容忽视。
