Research Abstract |
A data base of scoliosis patients including X-ray, chest computed tomography and moire topogram were made. We developed a computer program to analyze mire topograms and chest computed tomographies. Utilizing the software, studies were done to obtain parameters to assess the magnitude of a trunk deformity in scoliosis. The following preliminary results were obtained ; 1) The relation between cross-sectional deformity of the trunk and lung function was analyzed in 10 cases. No correlation was found between the Cobb angle and the lung function, whereas a strong correlation was found between the cross-sectional trunk area and the %VC. 2) The lung function after 20 of age were studied in the patients who underwent surgery in their adolescence. The average % correction in Cobb angle was 58.1%, whereas the average VC and the average % VC showed little change at the final follow-up compared to those of preoperative. The average % VC stayd larger than 80% at the time of follow-up in the cases in which the Cobb angle was less than 70 degrees preoperatively. It was less than 70% in the cases whose Cobb angles were more than 70 degrees preoperatively. 3) Among fifty-two idiopathic cases who completed brace treatment, 2% showed improvement, 79% unchanged, and 19% progression in Cobb angle. On the other hand, Hump Sum showed improvement in 39%, no change in 44%, and increase in 17%. In those cases in which the Cobb angle showed progression of scoliosis, 90% showed either improvement or no change in Hump Sum. These results indicate the effectiveness of the brace treatment in terms of the correction of the trunk deformity.
