In order to assess the risk of progression, several aspects must be taken into account which may cause the scoliosis to progress:
- number of curves: a scoliosis pattern with more curves has a worse prognosis
- age: the younger the child when scoliosis is detected, the worse the prognosis
- rotation: the greater the Cobb angle and rotation, the worse the prognosis
- gender: girls have a worse prognosis than boys
- signs of puberty: girls whose scoliosis is detected before menarche have a worse prognosis
- skeletal maturity: skeletally immature adolescents have a greater tendency to deformation
- sagittal profile: a flat back predisposes to spinal rotation
