There are two reasons why the fibula shows longitudinal motions. During dorsiflexion the push of the wedge-shaped trochlea tali causes an upward fibular motion; on the other hand, during weight bearing the contraction of the leg muscles effects a downward fibular motion. The specific level of the fibula results from these two correlating forces. While the upward fibular migration is a passive compensative movement, the downward fibular migration is an active stabilizing movement.
腓骨出现纵向运动有两个原因。在背屈时，楔形距骨滑车的推动导致腓骨向上运动；另一方面，在负重时，腿部肌肉的收缩导致腓骨向下运动。腓骨的具体位置由这两种相互关联的力量决定。腓骨向上移位是一种被动代偿运动，而腓骨向下移位是一种主动稳定运动。
