Vertebral Column: Regions and Curvature

5.5K
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...

General Structure of a Vertebra

5.0K
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous...

Summary

Increased vertebral height is linked to a higher likelihood of developing Type 2 Modic changes (MC2), a potential factor in low back pain. Further research is needed to confirm vertebral dimensions as independent risk factors for spinal degeneration.

Area of Science:

  • Spinal imaging and biomechanics
  • Radiology and diagnostic imaging
  • Epidemiology of musculoskeletal disorders

Background:

  • Low back pain (LBP) is a leading global cause of disability.
  • Modic changes (MC) are implicated in LBP etiology, potentially linked to mechanical stress on endplates.
  • Vertebral dimensions and physical activity levels may influence degenerative spinal changes.

Purpose of the Study:

  • To investigate the relationship between L4 vertebral dimensions (height, cross-sectional area, volume) and the presence of lumbar Modic changes (MC).
  • To explore the potential role of vertebral morphology in the development of spinal degeneration.

Main Methods:

  • A population-based birth cohort study of 1221 participants (Northern Finland Birth Cohort 1966).
  • Lumbar MRI was used to assess vertebral dimensions and Modic changes (MC1, MC2).
  • Moderate-to-vigorous physical activity (MVPA) was measured using accelerometers; logistic regression analyzed associations.

Main Results:

  • Vertebral height showed a positive association with Type 2 Modic changes (MC2) (OR 3.51).
  • Vertebral cross-sectional area (CSA) was not significantly associated with lumbar MC.
  • Vertebral volume was positively associated with any MC, but this finding was not significant when MC types were analyzed separately.

Conclusions:

  • Vertebral height is associated with the presence of Type 2 Modic changes (MC2).
  • The role of vertebral dimensions as independent risk factors for Modic changes requires further investigation.
  • This study contributes to understanding the biomechanical factors contributing to spinal degeneration.
