PURPOSE: Adolescent idiopathic scoliosis (AIS) is a complex three-dimensional (3D) spinal deformity, with transverse plane rotational components increasingly targeted by modern surgical techniques. Yet, clinical evaluation remains predominantly based on 2D radiographic parameters, including the widely used Lenke classification. In response, the 3D Classification Task Force of the Scoliosis Research Society (SRS) developed a comprehensive, clinically relevant classification system that remains intuitive, reproducible, and readily applicable by spine surgeons. This manuscript introduces the proposed SRS-Lenke-Aubin 3D classification and evaluates its ability to provide a structured and clinically meaningful 3D characterization of spinal deformities in AIS. METHODS: To maintain continuity with standard clinical practices, the system builds upon the established Lenke classification and introduces two complementary 3D descriptors: the orientation of the regional plane of deformation (ORPD) and the apical vertebral rotation (AVR). These indices capture transverse plane deformities at the regional and local levels, respectively. Each was independently assessed for the proximal thoracic (PT), main thoracic (MT), and thoracolumbar/lumbar (TL/L) regions using calibrated 3D reconstructions from biplanar radiographs. A population-representative cohort of 285 AIS surgical cases was used to evaluate the system. ORPD and AVR values were translated into categorical modifiers using predefined...
