Long-Term Outcome Following the Treatment of Pediatric Scoliosis

The investigators hypothesize that sagittal alignment and thoracic volumes will predict
successful treatment outcomes as measured by improved pulmonary function and health-related
quality of life in adolescent idiopathic scoliosis patients at a minimum 20-year follow-up.
Significant focus has been placed on the coronal plane in order to determine treatment
indications for scoliosis, but with new understanding about the important of sagittal balance
and pulmonary function, the treatment indications should be broadened. Thus, the
investigators propose the following study to explore parameters associated with a durable and
acceptable outcome following scoliosis treatment, minimizing the need for further surgery and
to optimizing quality of life and pulmonary health. Beyond the standard radiographs and
Scoliosis Research Society (SRS) scores, this study undertakes a comprehensive assessment of
health-related quality of life, chest asymmetry and body satisfaction scoring, sagittal plane
parameters, and 3D modeling of the childhood and current spinothoracic deformity. Thus, the
investigators research team is uniquely poised to determine broader treatment indications for
scoliosis. The overarching goal of this research effort is to determine new parameters based
on thoracic volume and sagittal plane alignment in addition to coronal deformity in order to
determine the appropriate treatment threshold for surgical intervention in children with
adolescent idiopathic scoliosis.
