BOTERO BOTERO, Diana Carolina et al. ANÁLISIS BIOMECÁNICO DE LA EPIFISIOLISIS DE LA CABEZA FEMORAL: COMPARACIÓN ENTRE FÉMURES SANOS Y ENFERMOS. Rev. ing. biomed. [online]. 2007, vol.1, n.2, pp.14-21. ISSN 1909-9762.

In this work, a finite element analysis (FEA) is accomplished to study the differences of stresses in the growth plate, that are produced in healthy and unhealthy femurs, and to evaluate the possible causes of this illness. Finite element models of 45 patients were developed. The results demonstrated a similar pattern of stresses in all the groups of femurs and also the appearance of greater stresses in the group with slipped capital femoral epiphysis than in the control group. It was also observed a strong dependency on the value of the axial-fisis angle from the group of femur analyzed and a bigger influence of the geometric factors than of the body mass index, in the incidence of the illness.

Keywords : Finite element analysis; Slipped capital femoral epiphysis; Biomechanical model; Growth plate.
