TERMOGRAPHIC MEASUREMENT AT BONE DRILLING PROCESS

Bone drilling is a frequent procedure applied as a first step for immobilisation of bone fracture. The next step is insertion of immobilization screws and plates. The drilling is performed with surgical drills. If the amount of heat, generated by drilling process, increases the temperature of the bone tissue above the critical limit, possible outcome (it may result in) is thermal necrosis. This paper presents the results of research conducted in order to establish a distribution of temperature fields in the region around drilled bore .Obtained results confirm the ranking of different drill types established by comparing cutting forces and maximal bone drilling temperature.
