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...

Anatomical Positions

Anatomical Positions

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Area of Science:

Orthopedics and Spine Surgery
Radiology and Imaging
Biomechanical Engineering

Background:

Global sagittal alignment is critical for spinal health and function.
Establishing normative data is essential for identifying spinal deformity.
Age and sex are known demographic factors that can influence spinal alignment.

Purpose of the Study:

To determine reference ranges for global sagittal alignment parameters.
To stratify these parameters by age and sex in a healthy cohort.
To provide a baseline for comparison in spinal deformity assessment.

Main Methods:

Retrospective cohort study of 518 patients without spinal deformity.
Biplanar full-body spine X-rays were analyzed.
Global sagittal alignment parameters were measured and stratified by age and sex.

Main Results:

Age was associated with increased cranial sagittal vertical axis to the sacrum (CrSVA-S) and hip (CrSVA-H) but decreased to the knee (CrSVA-K).
Male sex was associated with greater CrSVA-S, CrSVA-H, and ankle (CrSVA-A) compared to females.
No significant sex difference was found for CrSVA-K.

Conclusions:

This study provides normative reference values for global sagittal alignment.
Findings support operative planning and enhance understanding of spinal deformity.
Age and sex are significant determinants of normal sagittal alignment.
