A scoliometer is an instrument that is used to estimate the amount
of curve in a person's spine. It may be used as a tool during screening or as
follow-up for scoliosis, a deformity in which the spine curves
abnormally.
A scoliometer is similar to a level and is placed across the back
at the peak (apex) of the curve. The amount of tilt in the back is estimated in
degrees.
Doctors use X-ray images of the spine to diagnose scoliosis.
