Abstract
We investigated the thermal properties of a new bone cement, Boneloc®, during total hip replacement, using a thermocouple connected to a digital thermometer. In 10 of 11 cases the maximum temperature was below 43°C at the bone-cement interface in the acetabulum. This is a considerable reduction in the polymerization temperature in comparison with earlier studies of conventional bone cement. We found no difference regarding the setting time of the cement.
