The purpose of this study was to quantify the effect of sequential ligament transection (anterior talofibular, calcaneofibular, posterior talofibular, deltoid, and subtalar interosseous ligaments) on the rotational movement of the tibia and the calcaneus as associated with axial loading and dorsi-plantarflexing the foot. Eight cadaver foot-leg specimens were investigated using a unconstrained testing apparatus. As the ankle complex was axially loaded, almost the same internal rotation of the tibia and the same calcaneus eversion was found with and without the various degrees of lateral and medial ligament release; additional sectioning of the subtalar interosseous ligament tremendously increased the resulting tibial and calcaneal rotation. While tibial and calcaneal rotation from foot dorsi-plantarflexing did not alter significantly with transection of the lateral ligaments, almost no tibial and calcaneal rotation occurred after additional sectioning of the deltoid and subtalar interosseous ligament. These results indicate that, after release of the lateral ligaments, the foot becomes partially mechanically disconnected from the tibia by additional transection of the medial ligaments and even further disconnected after transection of the subtalar interosseous ligament.
本研究的目的是量化顺序性韧带切断术（距腓前韧带、跟腓韧带、距腓后韧带、三角韧带和距下骨间韧带）对与轴向负荷和足部背屈相关的胫骨和跟骨旋转运动的影响。使用无约束测试装置对8个尸体足腿标本进行了研究。当踝关节复合体受到轴向负荷时，无论外侧和内侧韧带松解程度如何，胫骨的内旋和跟骨的外翻几乎相同；距下骨间韧带的额外切断极大地增加了胫骨和跟骨的旋转。虽然外侧韧带切断后足部背屈引起的胫骨和跟骨旋转没有明显改变，但在三角韧带和距下骨间韧带额外切断后，几乎没有胫骨和跟骨旋转发生。这些结果表明，外侧韧带松解后，通过额外切断内侧韧带，足部与胫骨部分机械性分离，而距下骨间韧带切断后则进一步分离。
