This paper studies the problem and presents the results of different possibilities of avoiding the occurrence of thermal bone necrosis. In fact, in case of fracture of human bones, the best way to better and faster knitting is when a traumatologist fixes the fractured bone ends by drilling and setting the immobilization plates by screws. Because of the drilling process, the surrounding bone tissue is heated and if the temperature around the drilled bone hole exceeds the critical limit, this may… Expand

Figures and Tables from this paper

Effect of Drill Speed in Thermal Necrosis of Bone (An Animal Study)
TLDR
High speed bone drilling in 6000-7000 rpm, compared to conventional drilling, produces less heat and less thermal necrosis. Expand
An in vitro study of thermal necrosis in ultrasonic-assisted drilling of bone
TLDR
Experimental tests demonstrate that ultrasonic-assisted drilling offered lower thrust forces and lower process temperatures as compared to conventional drilling at 1000’r/min, and it is obvious that at 2000 r/Min, this method can be applied in the orthopedic surgery. Expand
Experimental and analytical investigation of the thermal necrosis in high-speed drilling of bone
TLDR
The results of this study reveal that the high-speed drilling of 6000–7000 r/min may effectively reduce the two parameters of maximum cortical temperature and duration of exposure at temperatures above the allowable levels, which in turn reduce the probability of thermal necrosis in the drill site. Expand
Parametric effect of vibrational drilling on osteonecrosis and comparative histopathology study with conventional drilling of cortical bone
TLDR
The specimens drilled with vibrational drilling show less damage in terms of osteonecrosis near the drill site which shows the significance of vibrational drills in case of orthopedic surgeries. Expand
Effects of rotary ultrasonic bone drilling on cutting force and temperature in the human bones
TLDR
Experimental investigations were performed to determine the effect of drilling parameters (rotational speed, feed rate and drill diameter) and techniques (conventional surgical bone drilling and rotary ultrasonic bone drilling) on cutting force and temperature generated during bone drilling, and it was found that the cutting force increased with increasing feed rate, drill diameter and decrease in rotational speed. Expand
Drilling of bone: A comprehensive review.
TLDR
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. Expand
Effect of Rotatory-Vibrational Bone Drilling in Lowering Thermal Necrosis (An Animal Study)
TLDR
Using ultrasonic vibration in drilling of bovine femur produces less temperature raise in drill site, and works independent of "feed rate" of the drilling when compared with conventional drilling. Expand
Investigation of thermal aspects of high-speed drilling of bone by theoretical and experimental approaches
TLDR
Examination of high-speed drilling of the bone using theoretical (based on Orthogonal Cutting theory and High-Speed Cutting theory) and experimental approaches indicated that application of high rotational speeds caused increased temperature rise of the Bone; only the rotational speed of 7000 r min −1 resulted in the minimum extent of temperature rise in the bone. Expand
Experimental investigation of temperature rise in bone drilling with cooling: A comparison between modes of without cooling, internal gas cooling, and external liquid cooling
TLDR
Comparing local temperature increases in different processes of bone drilling showed decreased possibility of thermal necrosis of bone in drilling with gas and liquid cooling, however, the results showed that the values obtained with the drilling method with direct gas cooling are independent of the rotational speed of drill. Expand
Comparison & Multiresponse optimisation of drilling characteristics of bovine bones with varying density
Abstract Drilling in human bone is an inevitable joining process during any fracture surgery. Excessive temperatures and durations during drilling process can result in the necrosis (death) of bone,Expand

Heat caused by drilling cortical bone. Temperature measured in vivo in patients and animals.
TLDR
The results of the present study indicate that temperatures measured in animal experiments are not applicable to the clinical situation where very high temperatures may arise on drilling in cortical bone, even if saline cooling is used. Expand
A study of the bone machining process--drilling.
TLDR
Results indicate that drill point geometry is critical when attempting to minimize drilling forces and that there appears to be a softening effect in bone when drilled at relatively high speeds. Expand

TLDR
In human-cadaver cortical bone, pinpoint design was a more significant factor, and predrilling was highly effective as a method of minimizing temperature elevation. Expand
