Eligibility Criteria
This trial is for boys and girls aged 10-16 with moderate to severe scoliosis who still have at least a year of growth left.

It's not for those pregnant, with certain allergies, substance abuse history, previous scoliosis surgery or other forms of scoliosis.Inclusion Criteria
Parents must be able to understand the study and sign the consent document. Assent will be obtained and documented as age appropriate
Patients and parents must be able to comply with study procedures and visits, including 3-month, 1-year, and 2-year follow-up visits
