Assessment of Angle velocity in girls with AIS
ScoliosisJournal report about Correction: Assessment of angle velocity in girls with adolescent idiopathic scoliosis Authors: Ferran Escalada, Ester Marco, Roser Belmonte, Esther Duarte, Josep Ma Muniesa, Roser Boza, Marta Tejero and Enric Cáceres Publiushed: 10 October 2009 Background Although it has been demonstrated that the peak height velocity (PHV) is a predictive factor of progression in adolescent idiopathic scoliosis (AIS), little is known about the usefulness of angle progression in clinical practice. The purpose of this study was to establish a relationship between height and angle velocities, as well as to determine if peak angle velocity (PAV) occurs at the same time than PHV. Methods A retrospective study of a cohort of girls with idiopathic scoliotic curves greater than 10°. Data of 132 girls who participated in a previous retrospective study about growth in AIS were used to calculate height and angle velocities. Relationship between height and angle velocities was est...
