Description of heat flow in a surgical cement layer

The hip joint alloplasty is one of the surgical treatments often performed in clinics and in traumaorthopaedic departments of hospitals. The popular method for connecting pelvis and femoral component with a bone during alloplasty is the use of a thin surgical cement layer. During a surgery, thermal properties of the cement, e.g., high polymerization temperature, appear to be harmful. The understanding of thermodynamic phenomena occurring during polymerization process is necessary to limit harmful cement influence on human body. Thus the description of the heat release due to chemical reactions is especially important. The paper deals mainly with the description of the heat source and temperature field in the surgical cement layer. Characteristics of the heat source in the cement were described. The temperature distributions in the cement layers at different values of thermal diffusivity coefficient were presented.
