Will your scoliosis still worsen if you are almost finished growing taller (less than 1" per year now)?

Curve size predicts: The goal of treatment of adolescent idiopathic scoliosis is to have the curves measure less than 30 degrees at skeletal maturity. The reason for this is that curves greater than 30 degrees are thought to progress a degree a year throughout a patient's lifetime. Curves less than 30 degrees at skeletal maturity are usually stable and should not have any clinical significance throughout adulthood.

Probably not: Scoliosis worsens maximally during the adolescent growth spurt (in the case of idiopathic scoliosis). If you are done growing (as checked by the growth chart), the scoliosis is not likely to progress if it is under 45 degrees.
