In eight healthy volunteers the angular and translatory motions of the fibula in relation to the tibia were investigated by roentgenstereophotogrammetry. Tantalum markers (0·8mm) were introduced into the tibia and fibula of the right leg. Examinations were performed with full body load in 10° increments of plantar-/dorsiflexion and pro-/supination of the foot, and during internal/external rotation of the leg. The reproducibility was found to be good. From 30° of plantar flexion to 30° of dorsiflexion there was an average widening of the ankle mortise of 1·04 mm and an average backward translation of the fibula in relation to the tibia of 1·03 mm. These displacements were statistically significant (P < 0·5). Seventy-two per cent of the width increase occurred in the plantar flexion part of the arc. The upwards/downwards displacement of the fibula in no case exceeded 0·1 mm. The outward/inward rotation of the fibula was small. Movements resulting from input pro-/ supination of the foot and from internal/external rotation of the leg were small.
在八名健康志愿者中，通过X线立体摄影测量法研究了腓骨相对于胫骨的角向运动和平移运动。将钽标记物（0.8毫米）植入右腿的胫骨和腓骨。在足部跖屈/背屈和内翻/外翻以10°递增以及腿部内旋/外旋的情况下，对受试者进行全身负重检查。结果发现可重复性良好。从跖屈30°到背屈30°，踝关节 mortise平均增宽1.04毫米，腓骨相对于胫骨平均向后平移1.03毫米。这些位移具有统计学意义（P < 0.5）。72%的宽度增加发生在弧形的跖屈部分。腓骨的向上/向下位移在任何情况下均未超过0.1毫米。腓骨的向外/向内旋转很小。由足部内翻/外翻以及腿部内旋/外旋引起的运动很小。
