Fibular function has long been a point of controversy in the literature. Until recently the fibula's role during gait has been thought of as entirely static. A review of the literature reveals an important dynamic function for the fibula in maintaining ankle mortise stability during weight bearing. Roentgenographic and anatomical studies confirm the hypothesis of progressive distal fibular descent. A taut interosseous membrane and deepened mortise result when be flexors of the foot contract during stance phase. Congenital deformities of the ankle may stem from aberration in the dynamic role of the fibula. Stress fractures and problems resulting from impaired distal migration and synostosis formation are interpreted as disorders of the dynamic role of the fibula.
腓骨的功能长期以来一直是文献中的一个争议点。直到最近，腓骨在步态中的作用一直被认为完全是静态的。文献综述揭示了腓骨在负重期间维持踝关节榫眼稳定性方面的重要动态功能。X线摄影和解剖学研究证实了腓骨远端进行性下降的假说。当足部屈肌在站立期收缩时，会导致骨间膜拉紧和榫眼加深。踝关节的先天性畸形可能源于腓骨动态作用的异常。应力性骨折以及由远端移位受损和骨桥形成导致的问题被解释为腓骨动态作用的紊乱。
