Background: We sought to determine a predictive model of data, differentiated by sex, from a radiographic study of the skeleton of the foot as an alternative to the classic study of the hand.
Methods: The study included 2,476 digital radiographs from 816 participants aged 0 to 21 years. The radiographs were from the Radiology Diagnostic Services of the Public Health System of Extremadura (Spain) from 2007 to 2011. The method used for their analysis consisted of assigning a numerical code to each ossification center of each growing bone of the foot and subsequently subjecting the data to a multivariate, decision tree, statistical analysis.
Results: The decision tree study identified the bones that have a common agedependent pattern of growth (as determined by a comparison of means test with P,.01) among individuals of the same sex. The quality of the decision tree predictions was evaluated in terms of the r2 coefficient. These values were r(2) =0.897 for females and r(2) = 0.890 for males, thus establishing the predictive goodness of the model of bone data to provide a specific estimate of the individual's age.
Conclusions: The foot is a good predictor of an individual's age from birth to complete bone maturity.
