Glossary

The terms you'll see across ScolioPath, in plain language.

Cobb Angle

The angle used to measure the size of a spinal curve on an X-ray — the standard way curves are described and compared over time.

Risser Sign

A staging system (0–5) that estimates skeletal maturity from the pelvis on an X-ray — used alongside age to judge how much growth may remain.

Sanders Stage

Another skeletal maturity staging system, based on the hand and wrist, sometimes used alongside or instead of the Risser sign.

ATR (Angle of Trunk Rotation)

A measurement taken during the forward bend test with a scoliometer, describing how much the trunk rotates — used as a screening indicator, not a diagnosis.

Idiopathic

Meaning the cause isn't identified — most adolescent scoliosis is described this way.

Bracing

Wearing an external brace, generally during growth, as one possible management option alongside monitoring or exercise.

Monitoring

Regularly checking a curve over time — through assessment and sometimes imaging — rather than a single one-off check.
