Bone cements used for the fixation of orthopaedic implants are implicated as one cause of the still limited lifetime of these devices. Any increase in the mechanical properties of bone cements would lead to a corresponding increase in prosthesis survivorship, thereby reducing morbidity and the need for revision procedures.
Various researchers are investigating the use of fiber and filler additives, changes in the chemical composition, and the use of new polymers to this effect. Our group applies recent developments in polymer science to increase the fracture toughness of bone cement by the addition of nanophase materials, thereby creating a nanocomposite structure.
