Advances in Bone Cements Based on Nanomaterials Research

Bone cements, as for example PMMA, have been extensively used in orthopaedic surgery since early 1960, when Sir John Charnley started using them on his patients for the fixation of both the femur and acetabulum. Nowadays, their use was extended to fixation of biomaterials, such as artificial joints, to bone, and filling of bone defects; recently, they have proved to be effective as drug-delivery systems. Although, since 1970, many successful total hip replacements using PMMA cement have been reported, unfortunately, a few failures of fixation have also occurred
