An effort was made to evaluate the importance of the supporting medial, lateral, and posterior ankle structures in preventing talar shift. A series of fresh autopsy specimen ankles were subjected to manual mediolateral and anteroposterior stressing of the talus as intact specimens and after deletion of credited stabilizing structures. The fibula and attached ligaments were major factors in preventing talar shift, both mediolaterally and anteriorly. The lateral supporting structures were also noted to securely stabilize the talus against posterior subluxation in the absence of the posterior and medial malleoli.
研究旨在评估踝关节内侧、外侧及后方支持结构在防止距骨移位方面的重要性。对一系列新鲜尸体踝关节标本进行实验，分别在距骨完整以及去除被认为具有稳定作用的结构后，对距骨施加手动内外侧及前后向应力。腓骨及其附着的韧带是防止距骨内外侧及前方移位的主要因素。还发现，在没有后踝和内踝的情况下，外侧支持结构也能可靠地稳定距骨，防止其向后半脱位。
