Objective: : To evaluate quality of life, using the SF-36, in patients with adolescent idiopathic scoliosis (AIS) who un-derwent surgery for deformity correction, comparing the results in the pre-and post-operative period.
Methods: : We evaluated 29 patients, 24 female, mean age 14.5 years, all patients had measurement of Cobb angle greater than 50º, and responded to the SF-36 questionnaire preope-ratively and on average two years after surgery.
Results: : There was improvement in all eight domains studied by the SF-36 after surgical treatment, with statistically significant improvement of the domains functional capacity physical aspects, pain and general state. Vitality and mental heal-th were those with the lowest percentage of improvement postoperatively.
Conclusion: : Surgical treatment of defor-mity in all AIS improved the functional aspects assessed by the SF-36, representing, in practice, better quality of life for these patients. Evidence Level II, Prospective Study.
