Age of onset is important in determining the prognosis of the patient.
In general, an earlier age of onset implies a worse prognosis. Again, perinatal and developmental history may be important in determining prognosis, or in determining if there are other underlying problems. This information may provide clues as to other underlying illnesses or syndromes which may play a role in the patient's scoliosis. Children of women with scoliosis should be screened repeatedly throughout their preadolescent and adolescent years. A positive family history usually implies a greater risk of progression.
