This graph gives an estimate of the area of the potential evolution of the vertebral deformity (orange area) considering the current Cobb angle of the primary curve, the age, the Risser test (calculated according to European standard), and the age at first radiograph.
The parameters have been calculated by evaluating 1800 radiographs of patients affected by scoliosis, not previously treated with a brace or specific exercises.
A scientific study validated the results and is under review for publication; proved to be reliable and useful in the daily clinic.
IMPORTANT: The natural history prediction is valid for the first available radiograph only and for subsequent radiographs only if no treatment was provided.
