How is mechanobiology involved in bone regenerative medicine?
2022, Tissue and CellCitation Excerpt :The combination of mathematical models and computer simulation methods has created many opportunities to better understand the mechanical behavior of bone tissue. Finite element method (FE) is the most common numerical method used to simulate bone that has been used at various scales of organs, tissues and cell surface (Oliveira, 2021; Ruffoni and van Lenthe, 2017; Verbruggen et al., 2012). Wolff's Law is the first concept to describe the relationship between shape and function in bones (Wolff, 1892).
Biomechanical Analysis of Human Femur using Finite Element Method: A Review Study

2021, Journal of the Mechanical Behavior of Biomedical MaterialsCitation Excerpt :See e.g. Cowin (2001), Helgason et al. (2008), Klika (2011), Oftadeh et al. (2015), Martin et al. (2015), Murphy et al. (2016), Bouxsein et al. (2020) and references therein. Since the early seventies, see e.g. Huiskes and Chao (1983), Zysset et al. (2013), Ruffoni and van Lenthe (2017), Kluess et al. (2019), Solórzano et al. (2020), numerical tools grounded on different constitutive assumptions have been also proposed. As well known, when dealing with the evaluation of the mechanical response of a structure, or a structural element, the fundamental ingredients that enter the evaluation are the shape, the constituent material, the boundary and loading conditions.
Multiscale modeling of bone tissue mechanobiology
2021, BoneCitation Excerpt :The combination of mathematical models and computer simulation methods opened many possibilities to advance in the understanding of mechanobiological behavior of bone tissue. The most common numerical method that has been used to simulate bone is Finite Element (FE) Method, which has been used at the different scales: organ [35], tissue [36] and cell level [37,38]. Only in particular cases, other numerical methods have been used, such as, boundary element method [39] or meshless methods [40] among others.
Joining soft tissues to bone: Insights from modeling and simulations
2021, Bone ReportsCitation Excerpt :Usually, these models are computationally inexpensive and can capture fairly well the overall stress-strain behavior at the tissue level. The obtained constitutive relations can then be implemented into continuum level finite element (FE) models (Ruffoni and van Lenthe, 2017), therefore accounting for more complex geometries and heterogeneous tissues (Thomopoulos et al., 2006; Gasser et al., 2006). However, continuum approaches cannot resolve mechanical events at the level of individual fibers (or at the fiber-matrix interface).
Effect of osteoporosis treatment agents on the cortical bone osteocyte microenvironment in adult estrogen-deficient, osteopenic rats
2018, Bone ReportsCitation Excerpt :The amount of strain actually transmitted to the embedded osteocyte is not known, but would also likely have similar effects across each of the models. Meanwhile, until such FE models become available, the state-of-the-art FE model applied here has been validated and thus supplies meaningful new information about the current topic (Ruffoni and van Lenthe, 2017). In clinical practice today, many patients are cycled through a number of bone active medications for the treatment of osteoporosis over many years.
