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.

Como se observa, en materia interpretativa la tendencia es también la de un fuerte formalismo en tanto se asume que el legislador, al elaborar la ley, deposita en ella todas las respuesta posibles y, en consecuencia, si el intérprete no es capaz de obtener -encontrar -la respuesta correcta para el caso propuesto, se trata o bien de la incapacidad del mismo para encontrarla, o de deficiencias insalvables en la redacción de la ley. con sus fundamentos en la forma de moral y filosofía (política). PECZENICK, Aleksander y HAGE, Jaap. Conocimiento jurídico, ¿sobre qué? Trad. Ángeles Ródenas. Doxa 22 (1999). Es claro, entonces, como en las dogmáticas aparecen entrelazados el problema de la justicia o de corrección material, de carácter deontológico, con el problema de la validez formal o de existencia del Derecho, de carácter ontológico, el problema de la eficacia de la norma jurídica, su aplicabilidad efectiva, de carácter fenomenológico, y el problema de los fines del Derecho, de carácter teleológico, circunstancias estas que, bajo la premisa de la neutralidad, se pretende claramente silenciar.
