Efficacy of conservative treatment of adolescent idiopathic scoliosis: end-growth results respecting SRS and SOSORT criteria

Methods In this retrospective study, the population included all AIS patients meeting the SRS inclusion criteria (age 10 years or older, Risser test 0-2, Cobb degrees 25-40°, no prior treatment, less than 1 year post menarche) that reached the end of treatment since our database started in 2003. We had 44 females and 4 males, average age at the start of 12.8 years ± 1.6 years. According to individual needs, 2 patients were treated with Risser casts followed by Lyon brace, 40 with Lyon or SPoRT braces (14 for 23 hours per day, 23 for 21 hours per day, and 7 for 18 hours per day), and 2 with exercises only. Outcome criteria included the following: SRS (unchanged; worsened over 6°; over 45° at the end of treatment; surgically treated; 2 years followup); clinical (ATR, hump, Aesthetic Index, plumbline distances); radiographic (Cobb degrees); and ISICO (optimum; minimum). ANOVA and chi-test were used for statistical analysis.
