Loosening of total joint replacements may be caused in part by thermal necrosis of bone in contact with the high temperature of the polymerizing PMMA acrylic cement. This study reports a method to reduce the temperature of the bone-cement interface below the temperature at which bone results in definite necrosis. By precooling the acetubular component to --84 degrees before insertion into the cement, the temperature during polymerization at a simulated bone-cement interface can be reduced from… CONTINUE READING
