The purpose of this study was to clarify the morphological characteristics of the cervical ligament (CL).
This study examined 80 legs from 40 Japanese cadavers. The CL was classified by the number of fiber bundles. The morphological features measured were fiber bundle length, width, thickness, and angle with the sagittal plane.
The CL was classified as follows: Type I, the CL is a single fiber; Type II, the CL consists of a superficial fiber and an inferior fiber; and Type III, the CL consists of a superficial fiber, intermediate fiber, and inferior fiber. Type I was seen in 15 feet, Type II in 57 feet, and Type III in 8 feet. In comparisons of morphological features within each type, significant differences were seen in fiber bundle length, width, and angle between superior fiber bundles and inferior fiber bundles of Type II and Type III. In comparison among types, the total fiber bundle width was significantly wider in Type II and Type III than in Type I, and the angle was significantly smaller in Type III than in Type I.
The results of this study suggested that each type may have different sub-talar joint control functions.
本研究旨在阐明颈韧带（CL）的形态学特征。
本研究检查了40具日本尸体的80条腿。CL根据纤维束的数量进行分类。测量的形态学特征包括纤维束长度、宽度、厚度以及与矢状面的夹角。
CL分类如下：I型，CL为单根纤维；II型，CL由浅层纤维和深层纤维组成；III型，CL由浅层纤维、中层纤维和深层纤维组成。I型在15只足中可见，II型在57只足中可见，III型在8只足中可见。在各类型内部形态学特征的比较中，II型和III型的浅层纤维束与深层纤维束之间在纤维束长度、宽度和夹角方面存在显著差异。在各类型之间的比较中，II型和III型的总纤维束宽度显著宽于I型，III型的夹角显著小于I型。
本研究结果表明，各类型可能具有不同的距下关节控制功能。
