Abstract

In functional bracing for idiopathic scoliosis, the role of the lateral pad acting through the ribs is very important. There are few reports, however, about the inclination of the ribs and the effectiveness of the brace. The relationship of the rib-vertebral angle (R. V. A.) on a level with the apex vertebra to the final correction was examined in thirtyfive patients (4 males and 31 females). Average age in scoliotic group was 12 years and 11 months at time of first examination. A lateral curvature of 29.7 degrees of Gobb's angle at pre-bracing was finally restored to 21.1 degrees. (29.3 per cent as correction rate). Final correction rate was 41.9 per cent in the group (7 patients) with larger R. V. A. than control, while 26.1 per cent in the group (28 patients) with smaller R. V. A.. We conclude from the results described above that measurement of the R. V. A. of the apex vertebra is useful in estimating the effectiveness of under arm bracing.
