Corrective Bracing for Severe Idiopathic Scoliosis in Adolescence: Influence of Brace on Trunk Morphology

Table 2

Values of the clinical parameters in braced patients versus admitted for surgical treatment patients matched for sex, age, and Cobb angle. The mean and standard deviation are presented. HS: Hump Sum. s: difference significant. ns: difference not significant.
