Some small curves do improve without treatment, and a few disappear. In a Greek school screening program, Soucacos and colleagues followed 839 children with idiopathic curves of 10° or more for a mean of 3.2 years: 27.4 percent improved by at least 5°, 9.5 percent resolved completely, and 14.7 percent progressed. In a Korean series of 169 untreated, skeletally immature children with curves under 25°, Modi and colleagues found 32.5 percent regressed, 41.4 percent stayed the same, and 26 percent progressed. Curves that are larger, found earlier in the growth spurt, or found in girls before their first period are the ones most likely to progress.
I am Dr. Justin Dick, DC, at Clear Life Scoliosis and Chiropractic Center in Charlotte, NC. Families sometimes hear "it might go away" at the first visit. This post shows what that statement rests on and where it stops applying.
What the Screening Data Show
Soucacos's study screened 85,622 children. Progression risk was highest in girls, before menarche, during the growth spurt, with curves of 30° or more, and with right thoracic or double curves in girls. Left thoracic curves showed a weak tendency to progress. The authors concluded that only a small percentage of screening-detected curves progress. That conclusion fits a population found by screening, which contains many small, mild curves. It does not describe a curve that is already 25° to 30° in a girl who has not started her period.
Why Some Curves Look Like They Went Away
Part of the "improvement" in these studies is measurement error. Carman and colleagues found the average difference between two readings of the same film was 3.8°, and a change had to reach about 10° before it could be called real with 95 percent confidence. A 5° improvement in a 12° curve can be noise. Modi also found that 46.1 percent of children changed curve pattern during follow-up before settling, so a single film is a snapshot. My post on Cobb angle measurement explains the error range.
Curves That Resolve Because the Cause Was Treated
Some curves are a response to something else. Mehta described five children whose scoliosis was provoked by painful bone lesions; two resolved completely after the lesion was treated. Zhou and colleagues reported a 12-year-old girl whose 50° thoracic curve resolved within two years of surgery for a high-grade L5-S1 spondylolisthesis. Those curves resolved because the driver was removed. They are not idiopathic scoliosis, and they are a reason to look for a cause when a curve is painful or atypical.
Infantile and Juvenile Curves
Figueiredo and James reviewed 98 children with juvenile idiopathic scoliosis. Seven resolved spontaneously, and 56 percent eventually had spinal fusion. Infantile curves have a different natural history, covered in my post on infantile scoliosis. My post on juvenile scoliosis covers ages 4 to 10.
What This Means for Watching a Curve
Observation is appropriate for many small curves, and the data above support that. It is a monitoring plan with defined intervals and thresholds, based on growth stage. My post on why "let's just watch it" is rarely neutral and my post on when scoliosis progresses the most explain how risk changes with growth.
How Dr. Justin Dick, DC Monitors Small Curves at Clear Life
At our Charlotte office, a small curve is staged by Risser grade and menstrual status, re-measured on comparable standing films, and judged against the 10° error threshold before any change is called. Painful or atypical curves are evaluated for an underlying cause.
Comparison
| Study | Population | Outcome |
|---|---|---|
| Soucacos 1998 | 839 screened children, curves 10°+ | Improved 27.4%; resolved 9.5%; progressed 14.7% |
| Modi 2010 | 169 untreated, Risser 0, under 25° | Regressed 32.5%; unchanged 41.4%; progressed 26% |
| Figueiredo 1981 | 98 juvenile idiopathic scoliosis | 7 resolved; 56% fused |
| Carman 1990 | Measurement reliability | About 10° needed to call a change real |
Research and Evidence
Evidence tiering: Soucacos is a prospective screening cohort; Modi a retrospective observational series; Figueiredo a case series; Mehta and Zhou case reports; Carman a reliability study. None tests an intervention. My statement that observation is a monitoring plan reflects SOSORT guidance and clinical practice.
My own published work tracks measured curve change over time. The 13-month follow-up case, Reduction of Adolescent Idiopathic Scoliosis: A 13-Month Follow-Up (Cureus, 2025, PMID 40062184), reports radiographic change in one adolescent and cannot separate treatment effect from natural history.

Frequently Asked Questions
Can scoliosis go away on its own?
Some small curves do. In 839 screened children, 9.5 percent of curves resolved completely and 27.4 percent improved by at least 5 degrees over about 3 years.
How often does a small scoliosis curve get worse?
In the same study, 14.7 percent progressed. In 169 untreated young children with curves under 25 degrees, 26 percent progressed.
Which curves are least likely to go away?
Curves in girls before their first period, during the growth spurt, 30 degrees or larger, and right thoracic or double curves had the highest progression risk.
Can an X-ray show improvement that is not real?
Yes. Two readings of the same film differ by about 3.8 degrees on average, and a change of about 10 degrees is needed to be confident it is real.
Should we just watch a small curve?
Observation fits many small curves when it has set intervals and thresholds. Dr. Justin Dick, DC at Clear Life Scoliosis in Charlotte, NC stages growth and re-measures on comparable standing films.
