Computer analysis of the bone regeneration strength in a model system of osteosynthesis by the Ilizarov fixator with static loads
The adequate complexity three-dimensional finite element model of biomechanical system with space, shell and beam-type elements was built. The model includes the Ilizarov fixator and tibial bones simulator with the regenerating tissue at the fracture location. The proposed model allows us to specify...

The adequate complexity three-dimensional finite element model of biomechanical system with space, shell and beam-type elements was built. The model includes the Ilizarov fixator and tibial bones simulator with the regenerating tissue at the fracture location. The proposed model allows us to specify the orthotropic elastic properties of tibial bone model in cortical and trabecular zones. It is also possible to change the basic geometrical and mechanical characteristics of biomechanical system, change the finite element mash density and define the different external loads, such as pressure on the bone and compression or distraction between the repositioned rings of Ilizarov device.
By using special APDL ANSYS program macros the mode of deformation was calculated in the fracture zone for various static loads on the simulator bone, for compression or distraction between the repositioned rings and for various mechanical properties during different stages of the bone regenerate formation (gelatinous, cartilaginous, trabecular and cortical bone remodeling). The obtained results allow us to estimate the permissible values of the external pressure on the bone and of the displacements of the Ilizarov fixator rings for different stages of the bone regeneration, based on the admittance criterion for the maximum of the stresses in the callus. The presented data can be used in a clinical condition for planning, realization and monitoring of the power modes for transosseous osteosynthesis with the external Ilizarov fixator. |
