Correlation between chronological age and the stage of union of the distal femur and proximal tibia epiphyses in a Romanian sample population

C. Dogaroiu, M. Avramoiu


Abstract: Radiological evaluation of the skeletal age represents an important tool for the estimation of the chronological age in the living. The aim of our study was to evaluate the relationship between the chronological age and the degree of epiphyseal fusion of distal femur and proximal tibia in a Romanian population, and to compare our results with the results of similar international studies. We examined 173 knee radiographs from subjects with known chronological ages, between 12 and 23 years for girls and between 13 and 23 years for boys. The degree of epiphyseal fusion was evaluated according to the 5-stage of union revised methodology elaborated by O’Connor et al. Some of our findings were in concordance with those of O’Connor: a very strong correlation between the distal femur and chronological age in both males and females, an earlier onset of epiphyseal fusion in females, a later fusion age for the proximal tibia. Other findings were slightly different: the correlation coefficient between age and fusion stage is lower in the Romanian subjects, and also the general mean age difference; the fusion processes occur slightly earlier in the Irish population.
Keywords: age estimation, radiographs, epiphyseal union, distal femur, proximal tibia.
