The rotational movements of the tibia and calcaneus that occur with dorsiflexion-plantarflexion and axial loading were studied in cadaver foot-leg specimens using an unconstrained testing apparatus. Independent of the foot flexion position, significant internal rotation of the tibia and eversion of the calcaneus were noted after the ankle complex was axially loaded. Independent of loading, 10 degrees of dorsiflexion resulted in 0.1 degrees of eversion and 2.1 degrees of internal rotation of the tibia. Conversely, 10 degrees of plantarflexion resulted in 1.6 degrees of inversion and 1.3 degrees of external rotation of the tibia. The induced rotational movements of the tibia and the calcaneus differed significantly between the specimens. These results suggest that the foot "axes" did not change by axially loading the ankle complex and they support previous reports that the ankle complex uses different axes for dorsiflexion and plantarflexion.
使用无约束测试装置，在尸体足腿标本中研究了背屈 - 跖屈和轴向加载时胫骨和跟骨的旋转运动。与足部屈曲位置无关，在踝关节复合体轴向加载后，观察到胫骨明显内旋和跟骨外翻。与加载无关，10度背屈导致跟骨外翻0.1度和胫骨内旋2.1度。相反，10度跖屈导致胫骨内翻1.6度和外旋1.3度。标本之间胫骨和跟骨的诱导旋转运动差异显著。这些结果表明，通过对踝关节复合体进行轴向加载，足部“轴”并未改变，并且它们支持先前的报告，即踝关节复合体在背屈和跖屈时使用不同的轴。
