概括
第一种类型 基底性发泄 (BI) 与大气层同化 (AOA) 改变了头骨脊柱的对齐. 这种状况减少了头骨和大 atlas 之间的空间,导致椎上部脊柱的后部位移.
科学领域:
- 神经外科 神经外科
- 放射学 放射学是一门学科.
- 整形外科 整形外科 整形外科
背景情况:
- 第一种类型的基底性发育 (BI) 具有亚特拉斯前弓 (AOA) 的同化特征.
- 据认为,AOA阻碍了头骨和第一个椎之间空间 (C1) 的正常发展.
- 这可能导致高椎脊柱的后部位移,影响神经结构.
研究的目的:
- 为了评估和比较类型I基底发育和AOA患者的头骨脊柱对齐,与正常人相比.
- 为了评估与底座和大孔相对的亚特拉斯和odontoid过程的位置关系.
主要方法:
- 对MRI和/或CT扫描与中线重建 (T1/T2加权图像) 的回顾性分析.
- 对30名正常受试者和27名II型IB患者的评估.
- 关键测量结果的比较:阿特拉斯前的位置,形过程的位置,以及C1-C2和前大边缘之间的距离.
主要成果:
- 与对照组相比,患有BI和AOA的患者表现出明显更大的C2-Basion距离 (t测试:t=4.18;p=0).
- 在BI组中,头骨和地图之间的空间显著减少.
- 正常受试者始终表现出与基础相对的前部位置,而BI患者表现出前部位置对齐或后部脱位,牙形过程侵入大孔.
结论:
- 亚特拉斯同化在I型基底性发育中阻止了正常的头骨-亚特拉斯定位.
- 这种情况与在发育过程中被认为是"滑回"的脊移动有关.
- 这些发现突出了AOA对椎生物力学和对齐的显著影响.

01:14Cranial Bones: Superior and Posterior View
2.0K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:28Articulations of the Vertebral Column
1.8K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
