"脊椎突出" (VP) 通常是第七个椎 (C7). 然而,这项研究发现,在不到50%的尸体中,最突出的脊椎过程 (SP) 是C7,突出显示了解剖学变异性.
科学领域:
- 人体解剖学 解剖学 解剖学
- 整形外科 整形外科 整形外科
- 临床解剖学的临床解剖学
背景情况:
- 第七个椎 (C7) 传统上被称为"突出脊椎" (VP),因为它的突出脊椎过程 (SP).
- 视视线作为临床评估和部区域干预的关键解剖地标.
- 教科书中对VP的描述可能不完全代表临床实践中观察到的解剖学变异性.
研究的目的:
- 为了确定宫和最上层胸脊椎中最突出的脊椎过程 (SP) 的实际水平.
- 为了评估第7椎 (C7) 在尸体群体中作为"突出脊椎" (VP) 的频率.
- 评估VP位置变化的临床意义,用于医疗程序.
主要方法:
- 研究了39具人类尸体 (平均年龄为77.5岁),这些尸体处于倾斜的位置,子部曲.
- 用钉触摸并标记在部底部最突出的脊椎过程 (SP).
- 剖析了宫区域,并使用盲人调查员来验证标记SP的脊椎水平.
主要成果:
- 第七椎 (C7) 仅在48.7%的病例 (n=19) 中被确定为最突出的脊椎过程 (SP).
- 第六椎 (C6) 是35.9% (n=14) 中最突出的SP,而C5在10.3% (n=4) 中是最突出的SP.
- 在5.1%的病例 (n=2) 中,第一个胸椎被确定为具有最突出的SP.
结论:
- 第七个椎 (C7) 的解剖学描述为"椎突出" (VP) 并不总是准确的,在不到50%的个体中观察到的变异性.
- 在最突出的脊柱过程 (SP) 的位置的显著变化对脊柱的临床检查具有关键的意义.
- 了解这种解剖变异对于准确的手术规划至关重要,特别是在部手术和脊髓麻醉中.

Vertebral Column: Regions and Curvature
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

Muscles of the Vertebral Column
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...
