In an in vivo kinematical investigation, the movements of the ankle/food complex induced by external rotation of the leg from an internally rotated position were analyzed by roentgen stereophotogrammetry. Radiopaque markers were introduced into the tibia, talus, calcaneus, navicular, medial cuneiform, and first metatarsal bones of eight healthy volunteers. Rotations occurring between these bones after 10 degrees increments of leg rotation were calculated in three dimensions. Movement of the leg from an internally rotated position to the neutral was found to induce motion mainly as internal rotation of the talus in relation to the tibia. Further external rotation induced motion mainly in the talonavicular and talocalcaneal joints, whereas a smaller amount of motion was seen in the joint between the navicular and the medial cuneiform.
在一项体内运动学研究中，通过X线立体摄影测量法分析了腿部从内旋位置进行外旋时踝/足复合体的运动。在八名健康志愿者的胫骨、距骨、跟骨、舟骨、内侧楔骨和第一跖骨中植入了不透X线的标记物。以10度的增量旋转腿部后，计算这些骨骼之间发生的三维旋转。发现腿部从内旋位置到中立位置的运动会主要引起距骨相对于胫骨的内旋运动。进一步的外旋主要引起距舟关节和距跟关节的运动，而在舟骨和内侧楔骨之间的关节中观察到的运动量较小。
