Who gets scoliosis?

There are many forms of scoliosis. The most common type (accounting for 80-85% of cases) is adolescent idiopathic scoliosis, which occurs after the age of 10, and predominantly affects girls. People of all ages can have scoliosis, but the focus of treatment is on children and adolescents. Of every 1,000 children, 3 to 5 develop spinal curves that are considered large enough to need treatment.
