Investigation of the flow characteristics of bone cements during cementation.
Zezula, Miroslav ; Poláček, Petr (oponent) ; Jančář, Josef (vedoucí práce)
Nowadays surgeons concern of the effect of viscosity of cement on cement penetration in the total joint replacement. Cement penetration depend on cement viscosity, prosthesis insertion time, cement curing time etc. The viscosity of bone cements is determined by the chemical composition, the temperature and the powder to monomer ratio. In this study will compaired viscosity and penetration into the bone of high and low viscosity cements. Viscosity will measured by two models. In first model the rod is insered in the cement with constant speed. In second model the cement is injected out from a syringe with constant speed. Cement penetration after injection into the bone will be measured by X-ray.
