Body height correction in scoliosis patients for pulmonary function test

We studied standing anteroposterior roentgenograms from 140 scoliosis patients and obtained a correction equation for body height by Cobb angle. This equation is applicable to patients with a double curve or special curve pattern as well as patients with a single curve. The repeatability of the method examined with this equation was higher than that with the previous correction method for body height by Cobb angle, and the difference between the corrected values and the measured values was small. Therefore, this method is considered to be more reliable.
