When examining a scoliosis radiograph, which direction does the vertebral body rotate in relation to the curve?

When evaluating a scoliosis radiograph, understanding the vertebral body rotation is crucial in assessing the curvature of the spine. In cases of scoliosis, vertebrae typically rotate towards the convexity of the curve. This rotation occurs due to the asymmetrical load placed on the vertebral structures.

When a spinal curve develops, muscles on the convex side may become tighter while the muscles on the concave side may become weaker. This muscle imbalance pulls the vertebrae into a position that rotates them towards the curve's convex side, resulting in a characteristic rotation that can be visualized on radiographs. This is an important factor in both diagnostics and treatment planning, as restoring proper alignment and function involves addressing this rotational aspect of the spine.

In summary, the vertebral body rotation towards the convexity reflects the mechanics of scoliosis and provides insight into how the curves develop and may progress.
