Study Notes
Structure of Vertebral Column
- Composed of individual vertebrae, which form both natural and pathological curvatures.
- Natural curvatures contribute to spinal strength and flexibility, while pathologic curvatures can indicate underlying health issues.
Regional Differences in Vertebral Column
- Cervical vertebrae have small bodies and bifid spinous processes, facilitating neck mobility.
- Thoracic vertebrae are larger, articulate with ribs, and have long spinous processes, limiting movement.
- Lumbar vertebrae are the largest, designed to bear weight and allow for more movement.
- The sacrum consists of fused vertebrae, providing pelvic stability.
- C1 (atlas) supports the skull and allows for nodding; C2 (axis) allows rotational movement.
- Common pathologies include Hangman’s fracture (C2) and fracture of the dens, which can be life-threatening.
Ligaments of Vertebral Column
- Various ligaments support the vertebral column; key examples include the anterior longitudinal ligament and ligamentum flavum.
- Ligaments are crucial for stability but can be damaged in hyperextension or over-rotation injuries.
- Ligamentum flavum, when hypertrophied, can contribute to spinal stenosis, narrowing the spinal canal.
Joints of Vertebral Column
- Facet joints provide stability and allow for movements such as flexion, extension, and rotation.
- Each region of the vertebral column allows different types of movement based on joint structure.
- Pathologies associated with the joints include:
- Herniated discs, which can lead to nerve compression and pain.
- Spondylolysis, often indicated by the "Scotty Dog Sign" on imaging, represents a defect in vertebra.
- Spondylolisthesis occurs when a vertebra slips forward over another, potentially causing nerve issues.
