¿Trauma o rasgo epigenético? La diferencia entre la fractura de la apófisis posterior del astrágalo y el Os Trigonum de la población aborigen de Maspalomas

Abstract

Os trigonum is found frequently in the population of the Maspalomas aboriginal human remains of Gran Canaria. There are also various cases of the posterior process fracture of the talus in this sample population. There are numerous scientific articles that indicate the difference between these two anatomical conditions but there is an absence of photos in the literature that clearly show the differences between them. In this preliminary study, 123 tali were analyzed and 23.2% of cases of os trigonum were found among them, as well as 4.8% of cases showing the fracture. The high frequency of the trait could be revealing specific ankle activity during late childhood and the existence of several cases of fractures could be affirming that this specific ankle activity continued into adulthood. The images found in this study could aid in the identification and differentiation of these anatomical conditions in future research.
