✦ Synopsis
One cause of aseptic loosening of cemented total hip ar-approximately 4 times greater in SUS-304 and 3 times greater throplasty is mechanical weakness at the interface between in titanium (Ti) alloy than those of uncoated metals, and this the metal stem and the cured bone cement. Adhesive acrylic strength did not decrease after 1 week's immersion in saline. bone cement containing 4-methacryloyloxyethyl trimellitate
The coating process using the 4-META cement can be peranhydride (4-META) was applied as a metal coating material formed at normal room temperature, so that metal stems for to increase the strength of the cemented fixation. The 4-META bone cement fixation could be coated during the course of cement has 2-3 times greater tensile bond strength to metals an operation resulting in potentially improved results of total than does commercial acrylic bone cement. The shear hip arthroplasty. ᭧ 1997 John Wiley & Sons, Inc. strength of the coated metals fixed with bone cement was
