Further study details as provided by A. Noelle Larson, Mayo Clinic:

Primary Outcome Measures:
  • Cobb angle and sagittal plane alignment [ Time Frame: 20 years ]
    Cobb angle and sagittal plane alignment at minimum 20 year follow-up after bracing, surgery or observation for adolescent idiopathic scoliosis

  • Scoliosis curve magnitude [ Time Frame: Nov. 2014 ]

Secondary Outcome Measures:
  • Pulmonary function testing [ Time Frame: 20 years ]
    Pulmonary function testing will be performed at 20 years following bracing, observation or surgery for scoliosis to assess association between coronal and sagittal plane alignment and pulmonary function.

  • Health-related quality of life [ Time Frame: Nov. 2014 ]

Enrollment: 66
Study Start Date: January 2013
Study Completion Date: October 2015
Primary Completion Date: October 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Long-Term Outcomes
Patients will be recruited who were diagnosed with adolescent idiopathic scoliosis prior to age 18 and before 1994 (minimum 20 year outcomes) with available xrays. Patients will be included who were treated with surgery, observation, or bracing. Patients will return for a one-time visit for new xrays, physical exam, health-related quality of life surveys, and pulmonary function testing.
Other: Long-term outcomes
Patients with a history of adolescent idiopathic scoliosis will return at a minimum of 20 year follow-up for new spine xrays, clinical exam, pulmonary function testing, and assessment of health related quality of life based on survey responses.

Detailed Description:
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.
