Corrective surgery for scoliosis typically becomes a consideration when the curvature of the spine exceeds 40 degrees. At this degree of curvature, the risk of progression increases, and the potential for significant health implications also rises. These implications can include compromised lung function and overall physical discomfort, along with aesthetic concerns.

Surgical intervention aims to stabilize the spine, reduce the curvature, and prevent further deterioration. Curvatures in the lower ranges, such as 10-19° and 20-29°, are often monitored and may be managed non-surgically with physical therapy or bracing, as they generally do not pose immediate health risks or significant functional limitations. As the curvature approaches the 30-40° range, close monitoring is essential to assess if surgical interventions will become necessary, but it is the curvature exceeding 40 degrees that primarily signals the need for more invasive corrective measures.
