Key Concepts

Biomechanics of Spinal Rotation

Spinal rotation is governed by the biomechanical properties of the vertebral joints, including the orientation of the articular facets and the configuration of supporting ligaments and muscles. These factors determine how much rotational movement is possible in each region of the vertebral column.

Range of Motion

Range of motion describes the extent of movement allowed by a joint or series of joints. In the spine, differences in vertebral shape, joint articulation, and the presence of additional structures such as ribs contribute to variations in flexibility and movement between regions.

Vertebral Column Regions

The vertebral column is segmented into regions—cervical, thoracic, lumbar, and sacral—each with distinct anatomical and functional characteristics. This segmentation influences the range of motion and specific movements permitted in each area of the spine.
