Study Notes
Characteristics of Vertebral Column
- The thoracic region of the vertebral column is characterized by posterior convexity and anterior concavity.
Comparison of Spinal Column with Normal Curves and Straight Rod
- A spinal column with normal curves is able to resist axial compression better than a straight rod, according to Kapandji.
Composition of Vertebra
- The posterior portion of a typical vertebra consists of pedicles and posterior elements.
Definition of Spinal Segment
- A spinal segment is defined as any two adjacent vertebrae, the intervening intervertebral disc, and all the soft tissues that secure them together.
Contact Forces in Vertebral Column
- The lumbosacral junction (L5 and S1) sustains the largest contact forces in the vertebral column.
