Finite element analysis of tibial bone plate: AIP Conference Proceedings: Vol 2523, No 1

The tibial bone plate fails due to corrosion, stress and treatment using bone plates cause stress shielding and bone plate loosening. The bone plate cannot be tested invivo on the patient so Finite Element Analysis is carried to analyze the bone plate fixed on the bone. In this investigation stress, strain and deformation were studied. A fractured model of the tibia is strengthened by bone plate using screw fixation The results obtained are for 5mm bone plate deformation, stress and strain on the bone plate is less compared to the deformation, stress and strain. It is concluded that corrosion of implants will affect the mechanical and biomechanical properties of the bone The FE model was validated by comparison with the human tibia model. Further investigation is required to study the biomechanics at the bone-screw interface.
