Sažetak
Surgery in case of bone fractures can be performed in two basic ways. The first method is conservative, without direct action on the bone, whereas the other, operative method is more advanced but requires direct contact with the bone. In the latter case, the traumatologist uses various tools and equipment in order to re-establish the primary physiological position of the fractured parts. One of the operative procedures includes also bone drilling in order to set the immobilization screws and plates. During bone drilling, the surrounding tissue is heated. If the amount of developed heat near the bore is high enough to increase the temperature of the bone tissue above the critical limit, this may result in thermal necrosis. The death of the cells due to the thermal necrosis around the drilled bore causes them to lose their adequate properties, and the screw joint gets loose over time. This work studies the influence of some of the technological parameters on the bone drilling temperature increase and recommends improvements in the selection of the technological parameters and geometry of the drill.
