AbstraktAbstract
Aseptic loosening is one of the most frequent reasons of failure of total hip joint replacement. The aim of the research was to investigate the processes playing role during cement degradation. To determine the degradation caused by cyclic mechanical loading radiological investigation have been used. The main problem of loosening - cement layer degradation and bone-cement interface debonding - have been investigated using a custom hip simulator. Image data from high resolution micro-focus X-ray Computed Tomography were used to reconstruct the complex geometry of the inner structure of the trabecular bone and the interface between the pelvic bone and the implant. Visualisation of trabecular bone structure and cement layer changes provided information about implant instability progress.
