“…Earlier studies have investigated the temperature increase whilst drilling human bone tissue, and how it relates to the amount of damage to surrounding vital tissue [12][13][14]. Lundskog et al described a significant decrease in vital bone tissue starting at a temperature of 50°C and exposure time of 30 seconds [10].…”

Purpose The purpose of this study was to evaluate the different temperature levels whilst drilling cemented and cementless hip prostheses implanted in bovine femora, and to evaluate the insulating function of the cement layer. Methods Standard hip prostheses were implanted in bovine donor diaphyses, with or without a cement layer. Drilling was then performed using high-performance-cutting drills with a reinforced core, a drilling diameter of 5.5 mm and cooling channels through the tip of the drill for constantly applied internal cooling solution. An open type cooling model was used in this setup. Temperature was continuously measured by seven thermocouples placed around the borehole. Thermographic scans were also performed during drilling. Results At the cemented implant surface, the temperature never surpassed 24.7°C when constantly applied internal cooling was used. Without the insulating cement layer (i.e. during drilling of the cementless bone-prosthesis construct), the temperature increased to 47°C. Conclusion Constantly applied internal cooling can avoid structural bone and soft tissue damage during drilling procedures. With a cement layer, the temperatures only increased to non-damaging levels. The results could be useful in the treatment of periprosthetic fractures with intraprosthetic implant fixation.

Abstract. Orthogonal cutting data is extremely useful since the measured force relationships can be used to model almost any machining process. However, previous orthogonal cutting investigations in bone have not tested conditions representative of clinical operations (i.e. very high tool speeds and small depths of cut, as in high-speed milling). In this paper, we aim to build a cutting force model that will be applied to the design, modeling, and optimization of a new robot-assisted high-speed milling system. Experimental results are presented for the cutting force components and the specific cutting energy of bovine cortical bone as a function of cutting tool geometry, depth of cut, and relative orientation between the cutting edge and bone structure. The cutting force magnitudes and trends prove to be considerably different from those previously reported in low-speed experiments, confirming the strong dependence of machining forces on cutting speed.

“…Various studies have been carried since late 1950 to optimise the bone drilling performance based on measurable parameters such as, drilling force, drilling torque, rotational speed, feed rate, temperature and accuracy of the drilled hole [9][10][11][12][13][14][15][16]. Although these studies resulted in various conclusions, they have not provided a functional relationship that represent the effects of drilling conditions, drill bit geometry and material behaviour on drilling forces.…”

Abstract. Bone drilling is an essential part of many orthopaedic surgery procedures, including those for internal fixation and for attaching prosthetics. Estimation and control of bone drilling forces are critical to prevent drill breakthrough, excessive heat generation, and mechanical damage to the bone. This paper presents a 3D finite element (FE) model for prediction of thrust forces experienced during bone drilling. The model incorporates the dynamic characteristics involved in the process along with the accurate geometrical considerations. The average critical thrust forces and torques obtained using FE analysis, for set of machining parameters are found to be in good agreement with the experimental results.
