The period from 1975 to 2005 marks a shift toward selective fusion options in scoliosis management, anchored to stable vertebrae, enabling preservation of spinal mobility while effectively addressing thoracic and adolescent idiopathic curves. Alongside surgical refinements, nonoperative care matured through bracing strategies supported by prospective data, risk-based prognosis, and clearer guidelines for timing and candidacy in skeletally immature patients. Historical Significance: These advances established a paradigm that prioritizes mobility and function, laying the groundwork for modern instrumentation, safer surgical techniques, and data-driven approaches to conservative management that continue to influence practice today.
