Risser Grades - used to help determine the risk of spinal curve progression
Ossification of the iliac apophysis starts at the anterior superior iliac spine and progresses posteromedially. The iliac crest is divided into 4 quadrants. The stage of maturity is designated by the number of quadrants that have ossified. For example, Risser grade 3 indicates that 75% of the iliac crest has ossified. Risser grade 4 indicates that all four quadrants have ossified. Risser grade 5 indicates that all 4 quadrants have ossified and fused to the iliac crest.
Risser Grades
The adolescent's skeletal maturity can help determine the risk of progression of more severe scoliotic curves:
Spinal Curves 5 - 19 degrees
Risser grades 0 and 1 - 22% probability of progressionSpinal Curves 20 -29 degrees
Risser grades 4 and 5 - 1.6% probability of progression (Lonstein and Carlson, 1984)
Risser grades 0 and 1 - 68% probablility of progressing 6 degrees or more during remaining growth.At Risser Grade 5 (skeletal maturity)
Risser grades 2, 3, and 4 - 23% probability of progressing (Lonstein and Carlson, 1984)
Curve less than 30 degrees = curves are, by and large, stable in adulthoodReferences:
Curves measuring 40 - 50 degrees = curves will increase an average of 10 - 15 degrees during a normal lifetime
Curves measuring greater than 50 degrees = curves will progress at a rate of approximately 1 - 2 degrees per year
