概括

盆腔前转 (AP) 显著影响腰部病 (LL) 模式,挑战盆腔发病率 (PI) 和LL之间的线性关系. 患有AP的无症状个体表现出明显的脊髓皮层参数和PI相关的,特别是在下腰椎.

科学领域:

脊柱生物力学脊柱生物力学
放射性分析放射性分析
整形外科手术整形外科手术

背景情况:

盆腔发病率 (PI) 和腰部病 (LL) 之间的关系传统上被视为线性.
骨盆前转 (AP) 代表一个独特的骨盆姿势,可能会改变这种关系.
了解这些变化对于准确的腰部手术规划至关重要.

研究的目的:

为了研究骨盆前转 (AP) 对腰部斜腰部参数的影响.
在无症状人群中阐明与PI相关的不同 lordosis 模式.
为了区分AP和非AP组之间的脊椎皮层参数.

主要方法:

对405个无症状患者的分析,分为AP (n=151) 和非AP (n=254) 组.
测量脊椎皮层参数,包括PI,PT,LL,SS,SVA,TPA,TLK,LT,LDI,以及从整个脊柱X射线影像中的细分位.
倾向性得分匹配 (PSM) 创建一个平衡PI队列用于比较分析.

主要成果:

与非AP组相比,AP组的PI和PT较低,SS和LL较高.
在PSM后,在AP和非AP组之间发现了PT,SS,LL,TPA和细分 (L1-2除外) 的显著差异.
在所有PI级别中,AP组始终显示出更大的LL和细分主,特别是在腰椎下部.

结论:

患有骨盆前转 (AP) 个体代表了一个独特的人群,具有独特的脊骨骨参数和PI相关的主病模式.
AP的特点是较低的PI和PT,较高的SS和LL.
与非AP组相比,在AP组中观察到细分主角病变的显著变化,特别是在下腰椎,与非AP组相比.

关键词:

无症状的人口无症状.腰部主症是指腰部主症.骨盆前转动 (pelvic anteversion) 是一个倾向性得分匹配的匹配方法顺的对齐是对齐的

Vertebral Column: Regions and Curvature

Vertebral Column: Regions and Curvature

The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
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...

Abdominal Regions and Quadrants

Abdominal Regions and Quadrants

To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...
