Optimization of drilling parameters for thermal bone necrosis prevention.
TLDR
It is envisaged that finite element simulation with RSM can simplify tedious experimental works and be useful in the clinical application to avoid bone necrosis.Abstract:
Background Bone drilling is a mandatory process in orthopedic surgery to fix the fractured bones. Excessive heat is generated due to the shear deformation of bone and friction energy during the drilling process. Objective This paper is carried out to optimize the bone drilling parameters to prevent thermal bone necrosis. The main contribution of this work is instead of only consider the influence of rotational speed and feed rate, the effect of tool diameter and drilling hole depth are also incorporated for optimization study. Methods Response surface methodology (RSM) was used to develop a temperature prediction model. Drilling experiments were performed using finite element software DEFORM-3D. Analysis of variance (ANOVA) was conducted to investigate the drilling parameters' effect. Desirability function in RSM was used to determine the optimum combination of drilling parameters. Results Results indicated that one applicable combination of drilling parameters could increase the bone temperature by less than 0.03%. To avoid thermal bone necrosis, eight reasonable combinations of drilling parameters were proposed. 3.3∘C residuals between in-vitro experiments and predicted values were demonstrated. Conclusions It is envisaged that finite element simulation with RSM can simplify tedious experimental works and useful in the clinical application to avoid bone necrosis.read more

TL;DR: In this article, numerical, experimental, and statistical approaches were combined to investigate the induced thermal damages by bone-drilling parameters, and the optimized parameters reduced maximum bone temperature (Tmax) (8.9-85.8°C) osteonecrosis diameter (OD) (5.16-10.07mm) and depth (OH) (3.35-5.50mm) more than previous studies.

High resolution cortical bone thickness measurement from clinical CT data
TL;DR: A novel technique is presented that is capable of producing unbiased thickness estimates down to 0.3 mm in the clinically relevant sub-millimetre range, where thresholding increasingly fails to detect the cortex at all, whereas the new technique continues to perform well.

An experimental investigation on thermal exposure during bone drilling
TL;DR: It is suggested that the exposure time during bone drilling far exceeds the commonly accepted threshold for thermal injury, which may prevail at significant distances from the drilled hole.
