Scoliosis in children is not just a curvature — it is a progressive condition that can worsen rapidly during growth. While mild curves may only require observation, certain cases demand timely surgical intervention.
In general, surgery is considered when the curve exceeds 45–50 degrees in growing children. However, the decision is far more complex than a single measurement.
What We Evaluate Before Deciding
At our centre, every child referred for possible scoliosis surgery receives a structured assessment before any surgical recommendation is made.
- Remaining growth potential (Risser grade, Sanders digital skeletal age)
- Curve progression rate over the last 6–12 months
- Underlying diagnosis — idiopathic, congenital, or neuromuscular
- Impact on lung function and posture
- Response to prior bracing, if attempted
When Is Surgery the Right Decision?
Surgery is not recommended lightly. In our practice, the following situations consistently point toward surgical intervention as the most appropriate path:
Progressive curve above 50° in a growing child. A well-fitted brace is designed to hold curves in the 25–45° range. It is not a tool to contain a curve that has already reached 50°. Bracing at this stage delays an inevitable surgery while allowing further deformity to develop — making the eventual operation more complex and the correction less complete.
Curve progression despite adequate bracing. When a child has been wearing a brace with verified compliance and the curve continues to progress past 45°, the biological forces driving the deformity have overcome what bracing can offer. Continuing non-surgical treatment at this point is not conservative — it is a delay with a cost.
Curves with neurological risk. Congenital scoliosis near the upper thoracic or cervicothoracic region can compress the spinal cord as it progresses. Curves associated with syringomyelia or tethered cord require coordinated neurosurgical management regardless of Cobb angle. In these cases, surgical timing is driven by neurological risk, not curve size alone.
The Real Risks of Delaying Necessary Surgery
Families sometimes hope that waiting will allow time for a better option to emerge. In most cases, however, delay carries concrete clinical consequences.
- Severe deformity progression — curves above 70–80° permanently reduce lung capacity
- Increased surgical complexity — larger curves require more fusion levels and carry higher blood loss
- Reduced correction potential — very rigid curves respond less completely to instrumentation
- Psychological impact — visible deformity during adolescence has documented effects on self-image and quality of life
Modern Surgical Techniques: What to Expect
Posterior spinal fusion with pedicle screw instrumentation is the established gold standard for adolescent idiopathic scoliosis. At our centre, average correction of thoracic curves at the time of surgery is 65–75% of pre-operative Cobb angle.
Most adolescents walk the day after surgery. Hospital stay is 4–5 days. Return to school is typical at 4–6 weeks, and non-contact sport at 3 months.
For children under 10 with severe curves — early onset scoliosis — we offer growth-friendly options including Magnetically Controlled Growing Rods (MCGR), which control the curve without stopping spinal growth. Fusion is deferred until skeletal maturity.
The goal is not early surgery — it is timely surgery. Intervening at the right moment preserves options; waiting too long forecloses them.
Getting a Second Opinion
If your child has been told surgery is necessary and you are uncertain, a second opinion from a paediatric spine deformity specialist is entirely appropriate. We regularly review cases referred from other centres. A meaningful second opinion requires the imaging, the curve history over time, and the child's skeletal maturity data — not just the most recent X-ray.
