This study focuses on treating idiopathic early-onset scoliosis, a condition where a young child’s spine curves sideways. Children will receive either a special brace, which is a device worn full-time to support the spine, or serial casts, which are like hard bandages wrapped around the body to help straighten the spine. The study will last until the spine curve either goes away, the treatment doesn't work, or after 2 years.

Key Points:

• Participants: Children under 3 with spine curve, and one parent/guardian.
• Treatment: Either braces or casts; no surgery.
• Commitment: Follow-up until results are seen, up to 2 years.

Before joining, children should not have had any previous treatments for their scoliosis. Parents must agree to participate and be able to fill out surveys. This study helps doctors and families make better choices for treating scoliosis. If you are interested in participating, check if your child meets the criteria and discuss with your healthcare provider. Your participation could help improve scoliosis treatments for children worldwide.
