Fig. 3From: The effect of spatial distances between holes and time delays between bone drillings based on examination of heat accumulation and risk of bone thermal necrosisa–c Thermographic images of bone drilling without cooling and without delay. Distances between the holes in a–c are 6, 12 and 16 mm, respectively. d–f Thermographic images of bone drilling without cooling at a distance of 6 mm. Time delays between drillings in panel d, e and f are 0, 5 and 10 s, respectivelyBack to article page
