Ligaments anatomy often show a huge anatomy variations between species and individuals. For example calcaneofibular ligaments (CFL) characterize the great variability of morphological shape or presence of additional bands. The aim of this study was to propose first anatomical classification of CFL concerning on human fetuses. We investigated thirty spontaneously-aborted human fetuses aged 18-38 weeks of gestation at death. Sixty lower limbs (30 left and 30 right) fixed in 10% formalin solution were examined. The morphological variability of CFL was assessed. Four types of CFL morphology were observed. Type I was characterized by a band shape. This was the most common type, occurring in 53% of all cases. Based on our study we are proposing a classification based on four morphological types of CFL. Types 2 and 4 are further divided into subtypes. Present classification may be useful to better understand the anatomical development of ankle joint.
韧带解剖结构在不同物种和个体之间常常存在巨大的解剖学差异。例如，跟腓韧带（CFL）的形态特征在形态或额外带的存在方面存在巨大的可变性。本研究旨在针对人类胎儿提出 CFL 的第一个解剖学分类。我们研究了 30 例在死亡时妊娠 18-38 周的自然流产的人类胎儿。对 60 条下肢（30 条左腿和 30 条右腿）进行了检查，这些下肢固定在 10%甲醛溶液中。评估了 CFL 的形态可变性。观察到了 CFL 的四种形态类型。I 型为带形。这是最常见的类型，占所有病例的 53%。基于我们的研究，我们提出了一种基于 CFL 的四种形态类型的分类。类型 2 和 4 进一步分为亚型。目前的分类可能有助于更好地了解踝关节的解剖发育。
