1. Preoperative BMI did not significantly influence curve correction, thoracic height gain, or EOSQ-24 quality-of-life scores in early-onset scoliosis patients treated with magnetically controlled growing rods.
2. Curve correction was comparable across weight groups, averaging 31% to 35%.
3. Thoracic height gain at two years was similar, with no significant differences by BMI category.
4. Overweight patients experienced higher complication rates, particularly implant breakage and wound-related issues.
5. BMI should be considered in risk stratification and perioperative planning despite not affecting radiographic outcomes.
