Mild Curve Progression Risk—Progression & Severity
A diagnosis of a “mild” scoliosis curve—often 10–20 degrees—can sound reassuring, but the real question is whether that curve is likely to grow. Understanding progression risk helps families decide how closely to monitor and when to act.
What Counts as a Mild Curve?
Mild scoliosis is generally defined as a Cobb angle between 10 and 20 degrees. Many of these curves, especially in near-skeletal maturity, may require only observation. In younger children, however, even a mild curve can represent the start of more significant changes.
Key Risk Factors for Progression
The likelihood of a mild curve worsening depends on:
- Age and growth remaining: younger children with much growth left are at higher risk.
- Curve pattern: thoracic and double curves tend to progress more than small lumbar curves.
- Family history: relatives with significant scoliosis.
- Initial curve size: a 19° curve in a rapidly growing child has a higher risk than a 12° curve.
Monitoring Mild Curves
At Dorsi Spinal Institute, mild curves are not ignored. We create a follow-up schedule that may include:
- Regular clinical assessments.
- X-rays or 3D scans at safe, evidence-based intervals.
- Home screening guidance for parents between visits.
When to Start Active Treatment
If a mild curve shows signs of progression—typically an increase of 5 degrees or more over a short time—we may recommend:
- Custom bracing for growing children or teens.
- Scoliosis-specific exercises to support posture and spinal health.
The aim is to stabilise or improve the curve before it reaches moderate or severe thresholds.
Prognosis of Mild Curves
Many mild curves never become clinically significant, especially when monitored correctly. Those that do progress can often be brought under control if treatment starts in time.
Next Steps
If your child has been told they have a mild curve, Dorsi Spinal Institute can provide a tailored progression risk assessment and follow-up plan focused on prevention and peace of mind.
