[Morphologic analysis of endoprosthesis materials with scanning electron microscopy].
The biomaterials used in endoprosthesis are subject to great dynamic and tribologic stress which they are not always able to withstand. Wear and fatigue fractures may ensue. The SEM is a valuable tool for controlling quality and determining the nature of faults in the material. Examination of the surfaces of a fatigue fracture usually reveals the cause of the fracture. The presence of manufacturing faults shows that the producer's quality control (the non-destructive-method) was not always sufficient. The SEM is also valuable for examining the polished surfaces of the prosthesis before and after load bearing in order to evaluate wear damages.
