Adolescent Idiopathic Scoliosis — Management

Lenke classification guides fusion levels using curve type, lumbar modifier, and sagittal modifier. Bracing is effective in skeletally immature (Risser 0–2) with 25–40° curves when worn adequately. PSF with pedicle screws is gold standard for surgical AIS; selective fusion aims to preserve motion segments. Assess sagittal profile to avoid hypokyphosis and junctional problems. Psychosocial support and cosmesis discussion are important in counseling.
