Thumb bone index may predict scoliosis growth spurts
NCT ID NCT03904914
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a new thumb bone staging system (TOCI) to predict skeletal maturity and curve progression in 1,500 teens with idiopathic scoliosis. Researchers evaluated thumb X-rays to see if the simple index could replace complex methods like the Risser sign or Greulich-Pyle atlas. The goal is to help doctors decide on bracing and treatment more easily in clinic.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could give doctors a quick, simple tool to predict growth spurts and scoliosis worsening, helping decide when to brace or treat.
What could go wrong
This is an observational study, not a treatment trial. The new index may not be more accurate than existing methods, and results may not apply to all patients.
