This study presents a constitutive model that is able to describe the curing phenomena of acrylic bone cements used in vertebroplasty. During the surgery the initial liquid bone cement is injected into a porous vertebra and penetrates it depending on the applied pressure. The procedure is accompanied by an exothermal phase transition from a viscous fluid to a viscoelastic solid. Moreover chemical shrinkage, thermal expansion as well as changes in temperature can be observed. After curing the… CONTINUE READING
