N2 - Fatigue fractures which originate at stress-concentrating voids located at the implantcement interface are a potential cause of septic loosening of cemented femoral components. Heating of the component to 44degreesC is known to reduce the porosity of the cement-prosthesis interface. The temperature of the cement-bone interface was recorded intral-operatively as 32.3degreesC. A simulated femoral model was devised to study the effect of heating of the component on the implant-cement interface. Heating of the implant and vacuum mixing have a synergistic effect on the porosity of the implant-cement interface, and heating also reverses the gradients of microhardness in the mantle.
