Parameters
Risser Classification & Skeletal Maturity for Scoliosis Result
--
Formula
Graded 0 to 5 based on excursion of iliac apophysis ossification from ASIS laterally to PSIS medially.Clinical Pearls
The classic radiologic staging tool used worldwide to determine timing of brace initiation, brace weaning, and surgical correction in adolescent scoliosis.
Limitations
Risser 0 encompasses a wide window of development; hand/wrist skeletal age (Sanders simplified maturity score) provides higher precision around peak height velocity.
