TLDR
The drill design for accurate temperature measurement at the drill point is described and it is shown that whilst the temperature may go to much higher than 55°C because of the poor conductivity of the bone the depth of damage is not critical insofar as screw fixation is concerned.About:

Cortical bone drilling and thermal osteonecrosis
Goran Augustin,Tomislav Zigman,Slavko Davila,Toma Udilljak,Tomislav Staroveški,Danko Brezak,Slaven Babic +6 more
TL;DR: Important drill and drilling parameters that could cause increase in bone temperature and hence thermal osteonecrosis are reviewed and discussed: drilling speed, drill feed rate, cooling, drill diameter, drill point angle, drill material and wearing, drilling depth, pre-drilling, drill geometry and bone cortical thickness.
Journal ArticleDOI
An X-ray diffraction study of the effects of heat treatment on bone mineral microstructure.
Keith Rogers,P. Daniels +1 more
TL;DR: The small, rod-like mineral crystallites changed from a highly anisotropically strained state to one with significantly larger equidimensional crystals possessing little microstrain when heated to > 800 degrees C, discussing in the context of graft bone substitutes and surgical heating of bone.
Journal ArticleDOI
Drilling of bone: A comprehensive review.
Rupesh Kumar Pandey,S.S. Panda +1 more
TL;DR: This review suggests that the further improvement in the area of bone drilling is possible and several consequential factors affecting bone drilling on which there no general agreement among investigators or are not adequately evaluated are identified.
Journal ArticleDOI
Experimental investigations of forces and torque in conventional and ultrasonically-assisted drilling of cortical bone.
TL;DR: Ulasonically-assisted drilling (UAD) was found to reduce a drilling thrust force and torque compared to conventional drilling (CD), and it is expected that UAD will produce holes with minimal effort and avoid unnecessary damage and accompanying pain during the incision.
Journal ArticleDOI
Survival and recovery of DNA from ancient teeth and bones
TL;DR: In this paper, the authors examined the mtDNA content of different hard and soft tissues in 42 ancient human and bovid specimens at a range of fragment lengths (77-235-bp) using real-time PCR.

Studies of Thermal Injury: II. The Relative Importance of Time and Surface Temperature in the Causation of Cutaneous Burns*
A R Moritz,F C Henriques +1 more
TL;DR: Although Leach, Peters, and Rossiter made a careful study of the pathological characteristics of different kinds of burns of guinea-pig skin, the extent to which these chges are representative of those that occur in cutaneous burning in man was not disclosed.

Factors Affecting the Determination of the Physical Properties of Femoral Cortical Bone
Elias D. Sedlin,Carl Hirsch +1 more
TL;DR: In this paper, the factors affecting the determination of the physical properties of the femoral Cortical bone were discussed, and the authors proposed a method to determine the physical property of femoral cortical bone.

Temperatures Measured in Human Cortical Bone when Drilling
Larry S. Matthews,Carl Hirsch +1 more
TL;DR: All forms of irrigation that allowed the stream of irrigating fluid to be directed to the point of penetration of the cortex were effective in limiting the increases in cortical temperature.

Heat and bone tissue. An experimental investigation of the thermal properties of bone and threshold levels for thermal injury.
TL;DR: The oxygen consumption rate (Qo2) of granulation tissue from cylinders implanted in bipedicle tube flaps of rabbits was measured weeks 2 to 7 in vitro in a Biological Oxygen Monitor®.
