Classification of Early-Onset Scoliosis

Early-onset scoliosis (EOS) is a complex and heterogeneous condition of significant diversity with respect to etiology, natural history, and management. Until recently, the lack of an organizing structure to condense the varied manifestations of EOS has slowed efforts to conduct the higher level of evidence studies necessary to establish best practices. That is, without a classification to reliably stratify children with EOS, it has been difficult to draw meaningful comparisons of outcomes before and after treatment. In light of this need, the Classification of Early-Onset Scoliosis (C-EOS) was developed to provide a comprehensive, practical, and predictive novel classification system designed exclusively for young patients with scoliosis.
