Scoliosis epidemiology is not similar all over the world: a study from a scoliosis school screening on Chongming Island (China)

School scoliosis screening has been carried out around the world. The screen program has never been performed on Chongming Island, the third largest island in China and characterized less population exchange with the rest of China. This study was designed to examine scoliotic parameters in children from Chongming Island and determine whether the parameters differed from those of the published data.
