Curve Progression Risk—Understanding the Numbers
Curve Progression Risk—Understanding the Numbers
The concept of “progression risk” underpins almost every major treatment decision in scoliosis care. Families want to know: will the curve get worse, and if so, how quickly?
Key Factors in Progression Risk
Important predictors include:
- Initial Cobb angle (larger curves have higher risk).
- Age and skeletal maturity (younger children with more growth ahead are higher risk).
- Curve pattern (certain thoracic or double curves progress more aggressively).
- Family history (relatives with significant scoliosis or surgery).
Risk Categories
Clinicians group patients into low, moderate, or high risk categories. This guides:
- How often to image and review.
- Whether to brace or just monitor.
- When to consider surgical opinions in very high-risk situations.
How Dorsi Calculates Risk
We use:
- Detailed growth and development assessments.
- Imaging trends over time.
- Current research and validated scoring systems.
Risk is communicated clearly so families can make informed decisions.
Changing Risk Over Time
Risk is not fixed. As a child grows, risk may:
- Increase during rapid growth spurts.
- Decrease as they reach skeletal maturity.
Our follow-up schedules adapt accordingly.
Next Steps
If you’ve been told a curve is “at risk” but don’t know what that really means, Dorsi Spinal Institute can provide a detailed progression risk assessment and plan.
