Descripción : We present a microstructural study and thermal diffusivity measurements at room temperature in twodifferent sections of bull dense bone, bull bone and commercial hydroxyapatite, the last two in powder form. A comparison was made between these measured values and those obtained from metallic samples frequently used in implants such as high purity titanium and 316L stainless steel. Our results show that the porosity and its orientation in the bone are two important factors for the heat flux through the bone. The hydroxyapatite, in compact powder form, presents a thermal diffusivity value very near to those obtained for the bone samples which give a good thermal agreement between these materials. Finally, one order of magnitude of difference among the thermal diffusivity values of metallic samples and those corresponding values to bone and hydroxyapatite was obtained, this difference being greater in titanium than in stainless steel.
