Synopsis of the survival proportions of the different studies available for comparison. For the treatment of an immature patient in the pubertal growth spurt the SpineCor seems worthless with a survival rate (8%) of less than observation, only (30%). The immature Schroth (physiotherapy) sample has a survival rate of 50% (estimated from the premature end results as the sample was not followed up to skeletal maturity), the Boston brace 70% and the Chêneau brace of the 1999 standard 80%. As the Schroth sample was not followed up to skeletal maturity (> 30 months only) this graph for physiotherapy is fictitious as it shows a follow-up of 4 years. The other limitation of the Schroth sample is the lack of homogeneity, also including patients not at actual risk. On the other hand, the prospective controlled study on Schroth seems to be the one providing the highest evidence for PT at this stage.
