Análisis del comportamiento biomecánico de la epífisis femoral en niños de 6 años afectada por necrosis avascular: modelo computacional

Abstract

Osteonecrosis (ON) or Avascular Necrosis is a pathology characterized by being a disease of weakening of the epiphysis of the long bones, being caused by the irruption of blood flow. In this work, a biomechanical analysis is carried out to understand the changes in the lines of transfer of the forces present in the femoral epiphysis in the presence of ON in children of 6 years of age, and that lead to fracture of the subchondral bone, from of the type of necrotic lesion. The analysis of the variation in the mechanical behavior is carried out by means of the method of finite elements, and the working domains were constructed from the use of computational tomography (CT).
