title: 3D patient-specific model of the tibia from CT for orthopedic use.
abstract: OBJECTIVE
  3D patient-specific model of the tibia is used to determine the torque needed to initialize the tibial torsion correction.
  
  
  METHODS
  The finite elements method is used in the biomechanical modeling of tibia. The geometric model of the tibia is obtained from CT images. The tibia is modeled as an anisotropic material with non-homogeneous mechanical properties.
  
  
  CONCLUSIONS
  The maximum stress is located in the shaft of tibia diaphysis. With both meshes are obtained similar results of stresses and displacements. For this patient-specific model, the torque must be greater than 30 Nm to initialize the correction of tibial torsion deformity.
