[The flexible metallic intramedullary nail (Mechanical model and theoretical analysis)].
An ideal mechanical model is proposed for the system which includes the fractured femur and the flexible rod. Developing through calculus the consequences of hypotheses which define the model, the rigidity and the resistance of the system are evaluated. The theoretical considerations and the numerical results of the analysis indicate the superiority of the non-parallel assembly of the rods in the case of high diaphysary fractures.
