Vertebral Column: Regions and Curvature01:16

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 the...

Summary
This summary is machine-generated.

This study establishes reference ranges for lumbar sagittal mobility in healthy adults. Findings reveal significant variations by age and sex, with mobility decreasing notably in older individuals.

Area of Science:

  • Biomechanics
  • Human Anatomy
  • Kinesiology

Background:

  • Lumbar sagittal mobility is crucial for daily activities.
  • Establishing normative data is essential for clinical assessment.
  • Previous studies show age and sex influence spinal mobility.

Purpose of the Study:

  • To determine reference values for lumbar sagittal mobility.
  • To analyze variations in mobility based on age and sex.
  • To provide data for understanding age-related changes in spinal function.

Main Methods:

  • A flexicurve device was used to measure maximal sagittal mobility.
  • Measurements were taken in the upper (T12-L4) and lower (L4-S2) lumbar regions.
  • Data were collected from 510 individuals with no history of low back pain, stratified by age and sex.

Main Results:

  • Wide variations in 'normal' lumbar sagittal mobility were observed across all ages.
  • Males exhibited higher flexion values; females showed higher extension and lower lumbar mobility.
  • Sagittal mobility decreased with age in both sexes, with reductions up to 50% in old age compared to childhood, particularly in flexion and upper lumbar measures.

Conclusions:

  • Reference ranges for lumbar sagittal mobility have been established.
  • Age and sex are significant factors influencing lumbar sagittal mobility.
  • A substantial decline in lumbar mobility occurs with aging, impacting daily function.
