Surgical decision is typically based on the degree of the curvature. The main consideration is whether the curve will progress. Curve progression in skeletally immature patients necessitates surgery to correct the curve and prevent further progression.
The treatment scheme for the skeletally immature patients are as follows;
- 0-20 degrees is observation with follow-up controls
- 20-40 degrees is bracing
- And >40 degrees is surgical treatment
Skeletally mature patients and adults do not have the same risk of curve progression between 0-40 degrees. Hence, the surgical decision for adults is given when the thoracic curves are >45-50 degrees and lumbar curves are >40 degrees.
