“…Additionally, planar radiographs of the distal radial epiphysis overestimate fusion in the age ranges between 15 and 19 years compared with MRI. 26 Studies that evaluate the grade of fusion of the LDRE by MRI do not define a particular bone age but rather grades of SM that are related to CA. This method avoids the limitations of having a bone age that may be higher or lower than CA.…”

Introduction: Although the grade of fusion of the left distal radial epiphysis (LDRE) observed by magnetic resonance imaging (MRI) has been linked to chronological age (CA), its relationship to Tanner stage of the genitals in the Latin American population is unknown. Objective: To evaluate the relationship of CA and sexual maturity with skeletal maturity (SM) determined by MRI of the LDRE in adolescent football players from Medellin, Colombia. Materials and methods: Cross-sectional study that included 60 male football players with certified legal age between 12 and 18 years. Medical evaluation and MRI of the LDRE using a 1.5 T scanner was performed according to a described protocol. The image reading was performed by 3 blinded evaluators. SM was classified as: A: immature; B: developing; C: mature, and interand intra-observer variability was assessed. Results: Among the football players included in the study, the average body mass index and body fat were 19.6 ± 2.0 kg/m 2 and 11.1 ± 1.2%, respectively. A correlation of CA and the Tanner stage of genital maturity with SM (Kendall's Tau b 0.686 and 0.693, respectively; P < .001) was found. All players classified as stage C were 17 or older and Tanner stage V. The inter-observer and intraobserver agreement showed a kappa index of 0.36 (P < .001) and 0.60 (P < .001), respectively. * Corresponding author. E-mail address: jagallo2000@yahoo.com (J.

Conclusion:A relationship was found between CA and sexual maturity and SM by MRI of the LDRE in adolescent football players. Classification by stage of SM in 3 categories could be more practical and have implications for competition. © 2015 Consell Català de l'Esport. Generalitat de Catalunya.

“…The stage classification of age-dependent ossification of the distal radial epiphysis put forward by Dvorak et al was recently analysed in a direct comparison between diagnostic methods using magnetic resonance imaging and those using projection radiography [38]. An extremely good correlation was ascertained between the methodspecific diagnoses, on the one hand, as well as between the ossification stage determined by means of magnetic resonance imaging and the chronological age of the test persons, on the other.…”

Comparison study of growth plate fusion using MRI versus plain radiographs as used in age determination for exclusion of overaged football players

Abstract: This article is of major importance as it is the first to show that x-rays significantly overrate the grading of fusion in this age group and therefore should not be used to exclude overaged players as is occurring now to the distress of many genuinely eligible players.
