Final answer:
In skeletally immature children with scoliosis, bracing with a TLSO can be considered when the Cobb angle of the curvature ranges from 25 to 40 degrees.
Step-by-step explanation:
In skeletally immature children with scoliosis, the Cobb angle is used to determine the severity of the curvature and guide treatment decisions. A Cobb angle of 25-40 degrees is typically the range at which orthopedists consider bracing as a treatment option. A TLSO (thoracolumbosacral orthosis) brace is commonly used to provide support and help control the progression of the curve.
