Abstract: X-rays of hands are used to evaluate a child's bone age. The BoneXpert program has automated bone age evaluation. BoneXpert has been validated in several different populations and for different races. The purpose of this study is to validate BoneXpert bone age rating for the Finnish majority population. A sampling of 400 hand x-rays of healthy Finnish children was collected. The chronological age of these children was compared to the Greulich and Pyle bone age given by BoneXpert for these images. The mean difference of these values was 0.079 years, for females 0.13, for males 0.028. These values are smaller than previous studies have found that have validated BoneXpert. In conclusion BoneXpert gives valid values for Finnish children's bone age.
