In a scoliotic curve, the spinous process rotates towards the concavity of the curve. This is a fundamental concept in understanding the mechanics of scoliosis. As the spine curves, one side of the vertebrae becomes more concave while the opposite side becomes more convex. The rotational aspect is a key characteristic of how scoliosis alters spinal alignment.

Specifically, when observing a scoliotic curve from the back, the angle created by the vertebrae that are part of the curve causes the spinous processes to move towards the side that is concave. This rotation contributes to the asymmetric appearance of the back, often leading to a rib hump on the convex side when the individual is bent forward. Understanding this rotational behavior is essential for effective treatment and management of scoliosis, including approaches in bracing and surgical interventions.

Recognizing this pattern helps in assessing the severity of the curve and informs the development of appropriate treatment plans, making it a crucial concept for practitioners in orthotics and prosthetics.
