New Perspectives On Bone Cement And Its Application

Abstract

One of the frequently encountered complications of arthroplastic operations is the loosening of prosthesis components. The main causes of component loosening are mechanical defects and sepsis. Mechanical defects are secondary to cement, bone or metal. In total hip arthroplasty defects, particularly femoral ones, primary separation of cement mass is considered as the main predisposing factor. Despite advances in cement materials and cement technologies, polymer acrylic still continues to be the weakest material used in arthroplastic operations. However, it is reported that arthroplastic defects are mostly caused by cementing technology rather than cement materials. With new cementing techniques it is possible to obtain a high quality cement mass. Consequently, a stable fixation with long life could be provided. In this report, recent advances in cement materials and techniques are reviewed. Also, the importance of techniques of cement preparation and application is emphasired.
