title: Prediction of Cobb angle in idiopathic adolescent scoliosis.
abstract: We did a prospective study of 291 children and adolescents with idiopathic scoliosis to identify possible correlations between clinical (scoliometer value, age, height) and radiographic (Cobb angle, Nash-Moe rotation, Risser iliac apophysis classification) parameters to predict the curve angle. There was a statistically significant correlation between thoracic, thoracolumbar, and lumbar scoliometer values and the thoracic, thoracolumbar, and lumbar Cobb angles, respectively (Pearson's r-0.685, 0.572, and 0.677, respectively). There was a statistically significant correlation between Cobb angle in the thoracic, thoracolumbar, and lumbar spine and the patients' age and height. Mathematical formulas that predict the Cobb angle of thoracic, thoracolumbar, and lumbar scoliosis using the scoliometer measurements are reported.
