Zhu F, et al. - This study investigated for surgical outcome equivalence between young adults and adolescents who underwent surgical correction of thoracic idiopathic scoliosis. Findings revealed that due to more flexibility, adolescent idiopathic scoliosis (AIS) patients would gain better radiographic curve correction compared with matched adult idiopathic scoliosis (AdIS) patients. Furthermore, AdIS carried the potential for an even worse radiographic outcome, when taking into account potential curve progression, whereas, delaying to adulthood may have similar health-related quality of life and attenuate the risk of adding-on phenomenon.
