High resolution finite element modeling of cemented bone-implant interface using X-ray microtomography
Original language description
The aim of the research was to investigate the cemented bone-implant interface behavior. The main problems (cement layer degradation and bone-cement interface debonding) during physiological loading conditions have been investigated using a custom hip simulator. The experimental setup was designed to allow cyclic loading of a sample of pelvic bone with implanted cemented acetabular component. The most unfavorable activity (downstairs walking) was simulated in two million cycles with 4Hz frequency. The process of damage accumulation in cement fixation was monitored by repeated scanning using high resolution micro-focus X-ray Computed Tomography. Use of micro-focus source and large high resolution flat panel detector allows investigation of structural changes as well as development of full-scale micro-structural models. 3D high resolution finite element model was reconstructed from the microCT data. The FE model is suitable for prediction of bone-implant interface behaviour.
