Abstract
Purpose: In this paper, the results of biomechanical studies conducted on an animal model are presented. The research shows the importance of detailed consideration of anatomical and functional differences relative to the human skeleton. The aim of this study was to assess the mechanical properties of cortical bone tissue, determine density values and compare different methods for measuring cancellous bone tissue density in terms of their practical application and limitations.
Methods: In the presented research, the Young’s modulus of canine cortical bone was determined using microindentation. The density of cancellous bone tissue in the proximal epiphysis of the canine femur was determined using several selected research methods.
Results: A comparison of Young’s modulus values for different bone areas showed that the highest values of the bone tissue’s Young’s modulus were obtained within the middle part of the bone shaft. It was observed that the distribution of density values is similar across the methods used, however, the range of the determined values differs slightly.
Conclusions: The determination of values and assessment of the mechanical properties of cortical bone tissue, along with the comparison of different methods for measuring cancellous bone tissue density, allows for more accurate prediction of fracture risk and more effective planning of surgical interventions.
