New 3D classification system for AIS introduced, SRS–Lenke–Aubin adds transverse plane insight, improving care.

A new 3D classification system for Adolescent Idiopathic Scoliosis (AIS) known as the SRS–Lenke–Aubin Classification has been unveiled in Milwaukee. This system provides crucial insight into the transverse plane, a component which was previously missing from the global standard for AIS classification. Introduced on February 2, 2026, this updated classification system aims to enhance understanding and treatment of AIS. This development marks a significant advancement in the field, with researchers hopeful that it will lead to improved outcomes for the approximately 4% of adolescents worldwide affected by AIS.
