Title

Preheating Acrylic Bone Cement Powder Is Not Recommended for All Brands

Abstract

One strategy that has been suggested for reducing the operating room time for cemented total joint arthroplasties-and, hence, for reducing the total cost of these procedures-is to accelerate the polymerization of the acrylic bone cement by preheating the powder to 65°C. We quantified the effect of preheating the cement powders on the fracture toughness and fatigue life of 3 cement brands that are widely used in clinical practice. The results suggest judicious selection of cements whose powders are to be preheated for use in cemented arthroplasties. © 2007 Elsevier Inc. All rights reserved.
