No. It's a well-known fact that scoliosis or curvature of the spine can get worse after skeletal maturity. Fortunately this doesn't happen in most cases. Curves greater than 30 degrees are the ones that tend to progress.

Some studies show one type of curve gets worse more often or faster than another but there's no real overall agreement on this.

Measurements are taken by X-ray. A change of 10 degrees or less is not considered a real or true change. The curve must be more than 10 degrees greater to signal progression.
