Study hypothesis
Bracing patients with adolescent idiopathic scoliosis in an early stage results in at least 5 degrees less mean progression of the curvature compared to the control group after two years of follow up.
Ethics approval
Received from local medical ethics committee

Multicentre randomised open label active controlled parallel group trial
Primary study design
Interventional
Secondary study design

Patient information sheet
Condition
Adolescent Idiopathic Scoliosis (AIS)
Intervention
Patients in the intervention group will be treated with a brace. The brace is a device that fits closely around the body to exert pressure to the trunk in order to push the spine into a straighter position. The patients will be advised to wear the brace every day for 18-23 hours. Patients are allowed to go to physiotherapy if they want to, but this is not obligatory. Patients of the control group will initially not be braced during the two study years, unless their curvature shows more than 10 degrees progression compared to the Cobb angle at inclusion. The patients of the control group are allowed to go to physical therapy, because physical therapy alone will not prevent further progression of the curvature. The orthopaedic surgeons will examine all patients every four months, amongst other things by X-ray.

Eligibility
Participant inclusion criteria
1. Firls and boys in the age group 8-15 years
2. Diagnosis of AIS has been established by an orthopaedic surgeon
3. not yet been treated by bracing or surgery
4. Further growth of physical height is still expected based on medical examination and maturation characteristics (Risser sign) established by X-ray. To expect further growth of physical height, patients only with Risser sign <3 will be included.
5. As agreed in the consensus by the different health professionals in the orthopaedic field, the Cobb angle should either be minimally 22 and maximally 29 degrees with established progression of more than 5 degrees or should be minimally 30 and maximally 35 degrees; progression for the latter is not necessarily established.
