Research Abstract

The ISIS developed by Harris and Turner-Smith in Oxford Orthop. Engineering Centre was investigated since Nov. 1987 comparing with Moire Topography using FM-40 for study on back shape analysis of idiopathic scoliosis concerning progression of the deformity. Following results were obtained at this time of moment, though a duration of follow-up period was short (averaged only for 7 months).
1) In 29 of 39 curvatures of idiopatbic scoliosis, where no treatment has been given, a correlation co-efficient between LAI (Lateral Asymmetry Index) and Cobb angle showed 0.75 in thoracic and 0.65 in thoracolumbar curvatures. 2) In 15 of 20 curvatures a comparative study on progression of the deformity was done for Lateral Asymmetry Index and Cobb angle. On the premise that 7 degrees in Cobb angle and 7 points in LAI as progression, a false negative was found in 10% and a false positive in 5 %. 3) In cases of brace treatment this discrepancy was found to be much increased, as false positive in 21%, falseneg. in 16%. 4) Based on the moire topography measurement for hump height in patients with curvature of 15 degrees and more, probability of predicted progression was studied before X-ray examination as follows; true positive in 8.1%, true negative in 70.9%, false negative in 2.4% and false positive in 18.8% (16 patients) respectively, regarding 7 degrees Cobb angle and 4mm hump heigh as progression.
Discussion; It was suggested that in follow-up study of idiopathic scoliosis progression can be presumed to a certain extent by analyzing the image of ISIS and moire topography. Further study of effective combination of these surface image technique should be required to reduce X-ray examinations.
