CHANGE OF TEMPERATURE DISTRIBUTION IN A TIBIA BONE BEFORE INSTALLATION OF A TRKh PLATE DURING EXECUTION OSTEOSYNTHESIS

Study of change of temperature distribution in a tibia bone during execution osteosynthesis of segmental fracture in the period of time between exposure of an area on a surface of the bone and installation of a TRKh plate and screws to this area was conducted in the article. Convective heat transfer occurs due to temperature difference between the area and air that flows around it. Temperature distribution in the model was obtained at 10 different values of time – from 6 to 60 minutes in increments of 6 minutes. Depth distribution of a front is more in a middle part of a diaphysis, where a medullary cavity is. Minimum temperature value in the model practically doesn’t change after 30 minutes and it is 34.5 °C.
