Ankle fractures that involve a fracture of the fibula above the syndesmosis (AO type C) associated with a medial lesion are always said to indicate rupture of the inferior tibiofibular syndesmosis. This study shows that fresh cadaver ankles subjected to a combination of abduction and direct lateral force over the shaft of the fibula consistently produce displaced bimalleolar ankle fractures without disruption of the inferior tibiofibular syndesmosis. The results of this study suggest that the presence of an AO type C ankle fracture does not necessarily indicate diastasis of the inferior tibiofibular joint and, therefore, internal fixation of the syndesmosis of the fracture may not be indicated.
涉及下胫腓联合上方腓骨骨折（AO C型）并伴有内侧损伤的踝关节骨折，一直被认为提示下胫腓联合破裂。本研究表明，对新鲜尸体踝关节施加外展力并直接作用于腓骨干外侧的联合作用力，始终会导致双踝移位骨折，而下胫腓联合未受破坏。本研究结果提示，AO C型踝关节骨折的存在不一定表明下胫腓关节分离，因此，骨折的下胫腓联合不一定需要进行内固定。
