The mechanical drilling process is a typical step in treating bone fractures to fix broken parts with screws and plates. Drilling generates a significant amount of heat and elevates the temperature of the bone, which can cause thermal osteonecrosis and damage to the surrounding bone tissue and nerves. Thermal inertia between heat flux and temperature gradient in nonhomogeneous interior structural medium-like biological tissues is arguable. Therefore, this paper proposes an analytical model of heat propagation in bone drilling for orthopedic surgery based on the hyperbolic Pennes bioheat transfer equation (HPBTE). Drilling experiments in bovine cortical bone samples were also carried out using an infrared thermography approach to confirm the proposed analytical model. Around the drilled hole surface, thermal necrosis is spread out from 1 to 10 mm. Increased feed rate reduces necrosis penetration distance and increases intense bone necrosis. The HPBTE includes thermal relaxation time effect and internal convective function of tissue perfusion rate. As these factors are not considered in the parabolic heat transfer equation (PHTE), the results show that the HPBTE is more accurate in predicting temperature and thermal osteonecrosis than the PHTE. As a result, proposed analytical model is a handy tool for calculating temperature to avoid thermal damage while improving process efficiency. Furthermore, it has the capability of controlling the manual or robotic drilling procedure for minimally invasive operations.

Background Here, the two-dimensional single-phase-lag (SPL) bioheat transfer model in biological tissue by considering the heat conduction law is introduced. The formulated SPL bioheat model is an extension of the bioheat transfer models proposed by Pennes, Cattaneo-Vernotte, and Tzou. Through this model, the thermal properties of living tissues, as well as the temperature distribution in living tissues, and the estimated resulting thermal damage due to laser irradiation are studied. The effects of delay time, blood perfusion, metabolism, and laser parameters on the spread of heat in the body and the resulting thermal damage are studied. Also, comparisons have been made between the results from the SPL and Pennes bio-heat models as well as the resulting thermal damage. The results of the SPL bio-heat model have been compared with previous results. The used numerical method is the (ADI) finite difference method. The proposed ADI difference scheme is unconditionally stable. The results have been presented graphically and discussed in detail.

“…Furthermore, standard electrometric constitutive models are insufficient for describing soft tissue's complex mechanical behavior. A thorough understanding of the thermal [13][14][15][16] and biothermo-mechanical [17][18][19] responses of biological tissues will aid in the design and optimization of heat transfer processes in biological tissues. Several models were proposed to study the mechanical behavior of biological tissues [20,21].…”

The principal objective of this work was to develop a semi-implicit hybrid boundary element method (HBEM) to describe the nonlinear fractional biomechanical interactions in functionally graded anisotropic (FGA) soft tissues. The local radial basis function collocation method (LRBFCM) and general boundary element method (GBEM) were used to solve the nonlinear fractional dual-phase-lag bioheat governing equation. The boundary element method (BEM) was then used to solve the poroelastic governing equation. To solve equations arising from boundary element discretization, an efficient partitioned semi-implicit coupling algorithm was implemented with the generalized modified shift-splitting (GMSS) preconditioners. The computational findings are presented graphically to display the influences of the graded parameter, fractional parameter, and anisotropic property on the bio-thermal stress. Different bioheat transfer models are presented to show the significant differences between the nonlinear bio-thermal stress distributions in functionally graded anisotropic biological tissues. Numerical findings verified the validity, accuracy, and efficiency of the proposed method.
