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.
这项前瞻性研究的目的是通过对121名正常儿童采用标准化体位和全长X线片，来确定儿童胸椎后凸放射学测量的“正常”范围。以均值加减两个标准差作为“正常”的定义，确定范围为20度至50度。各年龄亚组之间以及不同性别之间均无差异。
