Angle Velocity in Girls with Adolescent Idiopathic Scoliosis
Scoliosis Journal reported an assessment of angle velocity in girls with adolescent idiopathic scoliosis Authors: Ferran Escalada, Ester Marco, Roser Belmonte, Esther Duarte, Josep M Muniesa, Marta Tejero, Roser Boza and Enric Caceres Published: 16 September 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 10o. 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 estimated by th...
