Standardization of Criteria for Adolescent Idiopathic Scoliosis Brace Studies

Optimal inclusion criteria for future adolescent idiopathic scoliosis brace studies consist of: age is 10 years or older when brace is prescribed, Risser 0-2, primary curve angles 25 degrees -40 degrees , no prior treatment, and, if female, either premenarchal or less than 1 year postmenarchal. Assessment of brace effectiveness should include: (1) the percentage of patients who have < or =5 degrees curve progression and the percentage of patients who have > or =6 degrees progression at maturity, (2) the percentage of patients with curves exceeding 45 degrees at maturity and the percentage who have had surgery recommended/undertaken, and (3) 2-year follow-up beyond maturity to determine the percentage of patients who subsequently undergo surgery. All patients, regardless of subjective reports on compliance, should be included in the results (intent to treat). Every study should provide results stratified by curve type and size grouping.
