Abstract

Objective: To study the incidence of congenital posterior arch defects of the atlas and in combination with other congenital variations in the Chinese population.

Methods: We retrospectively reviewed 1405 images of cervical 3-dimensional computed tomography (3D CT) and 1284 images of head and cervical 3-dimensional computed tomography angiography (3D CTA), including images of 1539 male and 1150 female individuals. These images of cervical 3D CT and head and cervical 3D CTA were obtained in the Department of Radiology of 2 hospitals, Second and Third People's Hospital of Jingzhou, China, from January 2020 to October 2023. Congenital posterior arch defects of the atlas were classified according to the criteria of Currarino and colleagues. Congenital posterior arch defects of the atlas combined with other congenital variations including occipitalization of the atlas, the ponticulus posticus variation of the vertebral artery groove of the atlas, cervical fusion, and the transversal foramen of the atlas variant were also observed.

Results: A total of 2689 patients were included in this study. The overall prevalence of congenital posterior arch defects of the atlas was 0.74% (20 of 2689). There was no statistically significant difference in incidence between male (0.78%, 12 of 1539) and female patients (0.70%, 8 of 1150) (P > 0.05). Among all posterior defects, type A and B defects were found in 0.6% (16 of 2689) and 0.15% (4 of 2689) cases, respectively. There were no type C, D, and E defects and no anterior arch defects. However, in 20 cases of congenital posterior arch defects of atlas, 40% (8 of 20) combined with other congenital variations including occipitalization of atlas in 4 type A cases, bilateral complete ponticulus posticus variation of atlas vertebral groove in 1 type A case, C2-C3 fusion in 1 type A case, coexistence of unilateral complete ponticulus posticus variation of the vertebral artery groove of the atlas and unilateral unclosed transverse foramen in 1 type B case, and coexistence of unilateral unclosed transverse foramen in 1 type A case.

Conclusions: The incidence of congenital posterior arch defects of the atlas was low in a Chinese population. There was no difference between male and female individuals. Types A and B were the 2 major defects in this Chinese population, and the prevalence of type A and B combined with other congenital cervical variations were higher than those of types C, D, and E.

中国人群先天性寰椎后弓缺陷的发病率。
目的方法:回顾性分析1405张颈椎三维计算机断层扫描(3D CT)图像和1284张头颈部三维计算机断层扫描血管造影(3D CTA)图像,其中男性1539人,女性1150人。这些颈椎三维 CT 和头颈部三维 CTA 图像是 2020 年 1 月至 2023 年 10 月在荆州市第二人民医院和第三人民医院两家医院放射科获得的。并根据 Currarino 等人的标准对先天性寰椎后弓缺损进行分类,同时观察先天性寰椎后弓缺损合并其他先天性变异的情况,包括寰椎枕化、寰椎椎动脉沟后穹隆变异、颈椎融合、寰椎横突孔变异等:本研究共纳入 2689 名受试者。先天性寰椎后弓缺损的总发病率为 0.74%(20/2689)。男性(0.78%,12/1539)和女性(0.70%,8/1150)的发病率差异无统计学意义(P>0.05)。在所有后部缺损中,A 型和 B 型缺损分别占 0.6%(16/2689)和 0.15%(4/2689)。没有 C、D 和 E 型缺损,也没有前弓缺损。但在 20 例先天性寰椎后弓缺损病例中,40%(8/20)合并有其他先天性变异,包括 4 例 A 型病例的寰椎枕化,1 例 A 型病例的双侧完全寰椎后沟变异、1 例 A 型病例中 C2-3 融合;1 例 B 型病例中同时存在单侧完整的寰椎后凸变异和单侧不闭合的横突孔;1 例 A 型病例中同时存在单侧不闭合的横突孔。结论在中国人群中,先天性寰椎后弓缺损的发病率较低。男性和女性之间没有差异。A型和B型是中国人群中的两种主要缺陷,A型和B型合并其他先天性颈椎变异的发病率高于C型、D型和E型。

期刊介绍: World Neurosurgery has an open access mirror journal World Neurosurgery: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The journal''s mission is to: -To provide a first-class international forum and a 2-way conduit for dialogue that is relevant to neurosurgeons and providers who care for neurosurgery patients. The categories of the exchanged information include clinical and basic science, as well as global information that provide social, political, educational, economic, cultural or societal insights and knowledge that are of significance and relevance to worldwide neurosurgery patient care. -To act as a primary intellectual catalyst for the stimulation of creativity, the creation of new knowledge, and the enhancement of quality neurosurgical care worldwide. -To provide a forum for communication that enriches the lives of all neurosurgeons and their colleagues; and, in so doing, enriches the lives of their patients. Topics to be addressed in World Neurosurgery include: EDUCATION, ECONOMICS, RESEARCH, POLITICS, HISTORY, CULTURE, CLINICAL SCIENCE, LABORATORY SCIENCE, TECHNOLOGY, OPERATIVE TECHNIQUES, CLINICAL IMAGES, VIDEOS
