Abstract

By the implantation of hip-joint endoprothesis under application of Palacos bone cement, thermal energy is released during the polymerisation of the palacos fluid. After measuring the temperature in human hip-surgery, an average maximum temperature of 50.4°C showed on the interface between palacos and bone in the socket area, and at the femur a temperature of 45.2°C was registered.Because of the high coagulation temperature of the bone collagen (72°C) by a high specific heat and low thermal conductivity of the bone, thermal damage is improbable.Special measures for cooling are unnecessary, care should, however, be paid to economical curettage of the bones.
