Scoliosis in teens and young adults: a guide to read together
Short answer. Most teenagers with scoliosis never need surgery. Small curves are watched. Moderate curves in teens who are still growing are often braced. Surgery is usually discussed when a curve passes about 45 to 50 degrees. Once growth ends, small curves rarely get worse, and most teens stay active and play sports.
Who I see. Mainly older teens and young adults near or past the end of growth, young adults moving from pediatric to adult care, and families wanting a second opinion. Younger children still growing are usually best cared for by a pediatric spine specialist, and our team can help with that referral.
What happens at the first visit?
- 01
Talking
When the curve was found, any back pain, family history, growth and, for girls, when periods started.
- 02
Exam
Shoulders, waist and the forward-bend test, plus a quick check of nerves and reflexes.
- 03
Standing X-ray
Measures the curve (the Cobb angle) and shows how much growing is left, the biggest factor in whether a curve gets worse.
Questions to bring
- How big is the curve, and what type is it?
- How much growing is left?
- What’s the chance it gets worse? What would change the plan?
- When is the next X-ray?
- Any limits on sports or activities?
- (Teen) What should I tell my friends or coach?
Watched, braced, or surgery?
| Curve size | Still growing | Done growing |
|---|---|---|
| Under about 20–25° | Watch with periodic X-rays | Usually no treatment |
| About 25–40/45° | A brace is often recommended | Watch; curves over 30° are checked into adulthood |
| Over about 45–50° | Surgery is usually discussed | Surgery is often discussed |
General ranges. Exact thresholds depend on curve type, growth and how fast the curve is changing.
Does a brace really work?
Yes, if it’s worn. In the BrAIST trial, 72% of braced teens finished growing without their curve reaching the surgery range, compared with 48% of teens who were watched. Teens who averaged about 13 or more hours a day had success rates of 90% to 93%.
Do exercises help?
Scoliosis-specific programs such as Schroth may modestly reduce curve size and improve posture, especially for smaller curves and alongside a brace. They don’t replace a brace when one is recommended. General exercise and sports are encouraged.
Can my teen play sports?
Yes, usually as they feel able, including while braced. After fusion surgery, most teens return within about 6 to 12 months; collision sports are usually held until about 12 months.
School tips
- A well-fitted brace can usually be worn under regular clothes.
- Tell the school nurse; ask about gym, brace breaks and a place to change.
- After surgery, plan a gradual return, a second set of books or a locker near class.
After growth ends
- Under about 30°: curves rarely get worse in adulthood.
- About 30–40°: often grow slowly, about half a degree a year.
- Larger curves tend to keep growing.
Young adults with moderate or larger curves, or who had surgery as teens, should keep checking in with an adult spine specialist. Bring all prior X-rays (images, not just reports), brace history and operative reports. Adult scoliosis guide →
