Conservative treatment in adolescent idiopathic scoliosis with curves over 45°: is the measurement in Cobb degrees the only parameter to be considered?

Methods The study including idiopathic scoliosis with 45° or more, Risser 0-4, who had utterly deny any surgical intervention. Fulfill the inclusion criteria 160 patients. Of these, 104 patients has definite outcome, 28 abandoned treatment and 28 are currently under treatment. The minimum duration of follow-up was 24 months. Xrays was used to to obtain Cobb degrees and torsion of the apical vertebra (Perdriolle’s method). Three outcomes were distinguished in agreement with SRS criteria: curve correction, curve stabilization and curve progression. We have divided the sample in subgroup according to Risser (0-2; 3-4), to rotation (<20; >25) and to type of Curve. The Kruskal Wallis and Spearman Rank Correlation tests have been used as statistical tests.
