Risser Sign in Scoliosis

Skip to the navigation

Topic Overview

The Risser sign helps measures the risk that a curve in the spine ( scoliosis ) will get worse, or progress. It measures how much mature bone has developed (ossification) in the upper rim of the pelvis (iliac crest). Values range from 0 (least ossification and greatest risk of progression) to 5 (complete ossification and least risk of progression). This is determined by an X-ray .
