In clinical, forensic, legal and sport fields it is usefull to estimate the chronological age as well as the maturation status and therefore it is useful to determine it through the bone age. In 1983 Tanner et al. proposed the TW2 method, which was later modified and renamed as TW3. In Latin America, bone age studies of open populations using the TW2 and TW3 methods were carried out, but none of them concludes which of both is more accurate and for Mexico there are no published data on TW3. Objective: to explore which method (TW2 or TW3) is most appropriate to estimate bone age of children who share indoamerican ancestry and participate of similar cultural traits. Based on X-Rays of hand and wrist obtained between 1986 and 1987 in 393 youngsters (182 girls and 211 boys) from 6 to 17 years of age of Mixtec origin from the Heroica Ciudad de Tlaxiaco, Oaxaca, Mexico, bone age was estimated folowing RUS TW2 and RUS TW3 methods. Significant statistical differences were found between TW2 and TW3. Greater differences were found using TW2 method vs chronological age, than using the TW3, derived estimates which lay closer to chronological age.
