Description
Summary:This paper analyses the impact of exposure to Ringer’s solution, an isotonic solution relative to the body fluids, on the strength of bone cement. Research was conducted in order to determine moisture uptake and strength degradation. Prior to mechanical tests, the samples were seasoned in the solution simulating the human body conditions and subsequently measured to determine their increase in weight. Samples were then tested, using MTS Bionix testing system, for compressive strength according to ISO Standard. The data obtained from the measurements allowed to develop a statistical model for predicting cement absorption rate over a longer period of time. Compression strength of both seasoned and unseasoned samples was measured over time. The results were analysed statistically to show an effect of seasoning on cement strength. Cement samples show moderate moisture uptake over time, together with some decrease of compressive strength. Correlation between two above mentioned, measured factors was proven and linear model prepared. Using obtained models, one can estimate the cement strength and moisture uptake over time.
