What is minimal right rotation and minimal right thoracic scoliosis?

Minimal issue: The spine is designed to be like a stack of bricks, each level stacked straight and level with the next. there are thin cushions between the levels.Scoliosis defines a curve in any direction.The "thoracic" just means a focus in the spine with ribs. A minimal scoliosis can be how the spine grew, or be how the body deals with chest or back pain.This is common and not worth worrying about.
