Bone remodelling in implanted proximal femur using topology optimization and parameterized cellular model
2022, Journal of the Mechanical Behavior of Biomedical MaterialsCitation Excerpt :The clinical relevance of bone remodelling predictions depends on the accurate finite element (FE) modelling of implant-bone structures and the musculoskeletal loading conditions representing daily living activities (Bitsakos et al., 2005; Speirs et al., 2007; Geraldes et al., 2016; Mukherjee and Gupta, 2016b). Since simplifications in applied loading conditions influence the bone stress-strain distribution and consequently the remodelling outcome, consideration of multiple load instances of patient activities is necessary to predict bone adaptation (Carter et al., 1989; Cristofolini et al., 1995; Pidaparti and Turner, 1997; Huiskes et al., 2000; Polgar et al., 2003; Speirs et al., 2007; Geraldes et al., 2016). Bone is widely identified as an anisotropic material.
Assessment of finite element models for prediction of osteoporotic fracture
2019, Journal of the Mechanical Behavior of Biomedical MaterialsCitation Excerpt :One study showed that to obtain strain distributions similar to in vivo measurements, abductors, iliotibial band, adductors, vasti, gastrocnemii and hip contact should be modelled (Simoes et al., 2000), and the exclusion of these muscular forces will result in the overestimation of tensile and compressive strains (Polgar et al., 2003; Cristofolini et al., 2007). While some studies have shown the significance of including at least the abductor muscle forces, some have reported that the exclusion of the abductor muscles (Keyak et al., 2005; Cristofolini et al., 1995) or further muscle forces (Nalla et al., 2005) exhibit a critical difference in the predicted strength of FE models. However, further in vivo investigations are required to accurately quantify the muscular action and to assess whether the inclusion of thigh muscles provides a more realistic representation of femoral modelling.
Simulated hip abductor strengthening reduces peak joint contact forces in patients with total hip arthroplasty
2019, Journal of BiomechanicsCitation Excerpt :While not at the hip joint, this study provided quantitative evidence of the ability of increases in muscle forces to redirect contact forces during high-demand tasks. Cristofolini et al. (1995) simulated the forces of ten thigh muscles during early stance in gait on cadaveric femurs and found that the gluteus medius and minimus had over two times greater influence on vertical femur strain than the gluteus maximus, quadriceps muscles, and adductor magnus. The current study implemented the AMV probabilistic method to consider variability in musculoskeletal simulation in an efficient and accurate way.

A longitudinal compression scenario was modelled which reproduced a set-up commonly used in in-vitro mechanical tests described in the literature [21–25] to replicate a single leg stance configuration. Fig. 4 displays the simulation set-up.
