Scoliosis can affect children, teens, and adults, and adolescent idiopathic scoliosis is the most common type. Clinicians track severity over time using Cobb angle measurements from imaging, because curve change is central to management. Progression risk also varies with skeletal maturity: lower Risser scores (0–2) suggest more remaining growth and a higher chance the curve will worsen. On this page, you’ll explore diagnosis, monitoring, and treatment—from observation and bracing to surgery and potential complications.
Key Takeaways
- The SRS guideline commonly uses Cobb angle to measure curve severity and follow change over time, meaning imaging is central to management
- In adolescent idiopathic scoliosis, Risser sign 0–2 indicates greater remaining growth and higher progression risk, meaning younger/more skeletally immature patients are at higher risk
- Cobb angle measurement interobserver reliability for AIS is moderate, with typical standard deviations around a few degrees, indicating some measurement variability
- 1 in 300 people develop scoliosis severe enough to require medical attention, meaning 0.33% of people meet that severity threshold
- A 2.7-fold higher odds of experiencing low back pain among adults with scoliosis (adjusted odds ratio 2.7), meaning scoliosis is strongly associated with back pain
- A 1.6-fold higher odds of severe back pain in adolescents with scoliosis (odds ratio 1.6), indicating pain severity is elevated
- In adult deformity surgery, thromboembolic events occur in about 1%–3% of cases in large series, indicating a measurable clot risk
- In high-quality cohort data, surgery for adolescent idiopathic scoliosis is associated with a reoperation rate of about 7%, meaning roughly 7 out of 100 surgical patients may need another operation
- Surgical site infection occurs in about 1%–4% of posterior spine fusion procedures for scoliosis, indicating low but clinically important infection risk
- Bracing reduces the likelihood of progression to surgical-range curves by about 70% in adolescent idiopathic scoliosis, meaning braced patients are ~70% less likely to progress
- In BRAIST, mean wear time was about 13 hours/day reported in trial baseline and follow-up analyses, indicating not all participants achieved full-time wear
- JAMA 2016 (META-analysis) estimated bracing reduces curve progression risk by 53% vs no brace, indicating substantial protective effect
- In the U.S., the mean inpatient cost for scoliosis-related spinal fusion rises with increasing comorbidity burden (higher CCI), indicating patient complexity increases spending
- In adult deformity, greater preoperative disability measured by Oswestry Disability Index correlates with higher postoperative resource use in claims-based analyses, indicating disability drives cost
- In 2022, the global spinal implants market size was about $7.0 billion (latest year cited in report), indicating a market segment relevant to scoliosis instrumentation
Scoliosis severity is measured by Cobb angle, and growth and bracing strongly influence progression and pain risk.
