Abstract

The purpose of this prospective study was to determine the range of "normalcy" in the radiologic measurement of thoracic kyphosis in children by using a standardized position and full-length radiograph in 121 normal children. Using +/- two standard deviations from the mean as the definition of "normal," a range of 20 degrees - 50 degrees was determined. There was no difference between the various age subgroups or between genders.
