structural parameters - Opis:
- Since the 1960s UHMWPE has been the material of choice for bearing surfaces in total hip replacements. In spite of its clinical success over years, a large number of necessary revisions has been recently reported. The clinical life span of the hip prostheses is limited by weardebris-induced osteolysis and aseptic loosening. The problem is very complex because of the variety of factors affecting UHMWPE. Nowadays, scientists are working on how optimally adjust the material properties and the implant design in order to increase wear resistance and retain other mechanical properties. The aim of the study is to investigate structural parameters of two UHMWPE material states – conventional (non-crosslinked) and crosslinked. Those types of UHMWPE show slightly different properties, which can affect further behaviour in human body. The comparison between conventional and crosslinked UHMWPE is presented. Differential Scanning Calorimetry (DSC) is the analysis method applied in the research. The structural parameters of UHMWPE are correlated with its mechanical and tribological properties.
