ORIGINAL ARTICLE: PDF OnlyThe Use of the ISIS Optical Scanner in the Management of the Braced Adolescent Idiopathic Scoliosis PatientTREDWELL, S. J. MD*; BANNON, M. BSc, MSc† Author Information *Vancouver, Canada †Medical Resource Unit, Department of Orthopaedic Surgery, Faculty of Medicine, University of British Columbia, Canada. Spine: October 1988 - Volume 13 - Issue 10 - p 1104-1105 Buy Abstract Thirty-four adolescent female patients with right thoracic idiopathic scoliosis were followed for a mean of 8.6 months to document progression of scoliosis curvature during bracewear. Prediction of change by deviation of the lateral asymmetry index on ISIS examination were compared with measured change on standard upright roentgenograms. A one-to-one correlation was found in 50% of the patients; five patients were predicted to have stayed the same or decreased by ISIS and showed increase on x-ray measurement. Eight patients were predicted to have stayed the same or decreased by x-ray measurement and showed increase by ISIS. Although a weak positive correlation exists between change by x-ray examination and change by ISIS examination in a braced population, the clinical usefulness of the ISIS method in following a braced population has not been proven. © Lippincott-Raven Publishers.
