A method for bone-cement interface thermometry: An in vitro comparison between low temperature curing cement Palavit® and Surgical Simplex® P

Abstract

Previous temperature measurements at the bonecement interface have all shown large variations. To evaluate more precisely the temperature profiles during cement curing, a new experimental model was developed. Eight thermocouple electrodes at the bone-cement interface for each test specimen were used for continuous temperature recordings. Temperature profiles of Palavit® was compared with those of Surgical Simplex® P in an in vitro model using isolated pig femurs. Defects of 12 × 17 mm in the femoral metaphysis were filled with cement. In six tests with each type of cement, Palavit® peaked at a temperature of 50 ± 0.5 °C, whereas Surgical Simplex± P peaked at 60 ± 0.7 °C. Core temperatures reached peak values of 70 ± 0.8 °C and 95 ± 2.2 °;C for Palavit± and Surgical Simplex® P, respectively.
