Retrospective analysis of idiopathic scoliosis medical records coming from one out-patient clinic for compatibility with Scoliosis Research Society criteria for brace treatment studies

BACKGROUND: First author attempted to analyse medical records of patients with idiopathic scoliosis for compliance with the Scoliosis Research Society brace studies criteria. A retrospective analysis of medical records of 2705 girls treated from 1989 to 2002 was carried out. METHODS: Age, Cobb, Risser and menarchal status were analyzed for compliance with the Scoliosis Research Society brace studies criteria: a) age ≥10 years, b) Risser 0–2, c) 25–40° Cobb angle, d) no earlier treatment, e) patients before first menses or not more than one year from first menses. RESULTS: It has been found that 183 girls out of 2705 were ≥10 years old and in the range 25–40° Cobb angle. One hundred two out of 2705 patients revealed eligible for brace effectiveness study according to SRS 2005 criteria. 120 out of 2705 patients revealed eligible for brace brace effectiveness study according to SRS-SOSORT 2014 criteria. CONCLUSION: The excluded patients revealed too old or with too significant Cobb angles. This indicates the changing criteria for scoliosis brace treatment over the time. Direct comparison of current results of brace treatment with historical series of cases turns out to be very difficult.
