Abstract

Background: To study the anatomy of the Chinese occipital condyle and its position relative to the occipital foramen and skull.

Materials and methods: Measurements were taken from 106 adult Chinese skulls using a Cartesian coordinate system centered on the foramen magnum. Measurements included the longitudinal diameter of the foramen magnum, distances from various points on the occipital condyles to the foramen magnum and skull landmarks, and the occipital condyle classification index (OCI) and skull-occipital condyle classification index (SOCI).

Results: OCI categorized the position of the foramen magnum and occipital condyles into three groups: OCI ≤ 0.40 (3 cases, 2.83%), 0.40 < OCI ≤ 0.50 (75 cases, 70.75%), and OCI > 0.50 (28 cases, 26.42%). SOCI categorized the relationship between the skull and occipital condyles into two groups: 0.5 < SOCI ≤ 0.6 (49 cases, 46.23%) and 0.6 < SOCI ≤ 0.7 (57 cases, 53.77%). Four relationship types were identified based on specific measurements: Type I (23 cases, 21.70%), Type II (42 cases, 39.62%), Type III (4 cases, 3.77%), and Type IV (37 cases, 34.91%).

Conclusions: Sagittal movement of the occipital condyle affects the cervical spine's curvature. Asymmetry between the occipital condyles and the foramen magnum may misalign the skull with the body's coronal plane.

中国人头骨枕骨髁位置的形态学观察及其潜在的临床意义。

背景：研究中国人枕骨髁的解剖结构及其与枕骨孔和头骨的相对位置：研究中国人枕骨髁的解剖结构及其与枕骨大孔和头骨的相对位置：使用以枕骨大孔为中心的直角坐标系对 106 个中国成年人头骨进行测量。测量内容包括枕骨大孔的纵向直径、枕骨髁上各点到枕骨大孔和头骨地标的距离、枕骨髁分类指数（OCI）和头骨-枕骨髁分类指数（SOCI）：结果：OCI 将枕骨大孔和枕骨髁的位置分为三组：OCI≤0.40（3例，2.83%）、0.400.50（28例，26.42%）。SOCI 将头骨和枕骨髁之间的关系分为两组：0.5 < SOCI ≤ 0.6（49 例，46.23%）和 0.6 < SOCI ≤ 0.7（57 例，53.77%）。根据具体测量结果，确定了四种关系类型：结论：结论：枕髁的矢状位移动会影响颈椎的曲度。枕骨髁与枕骨大孔之间的不对称可能会导致头骨与人体冠状面错位。

期刊介绍： "Folia Morphologica" is an official journal of the Polish Anatomical Society (a Constituent Member of European Federation for Experimental Morphology - EFEM). It contains original articles and reviews on morphology in the broadest sense (descriptive, experimental, and methodological). Papers dealing with practical application of morphological research to clinical problems may also be considered. Full-length papers as well as short research notes can be submitted. Descriptive papers dealing with non-mammals, cannot be accepted for publication with some exception.
