“…details regarding stress transfer between constituents in various mineral-collagen arrangements and its effect of macroscopic behaviour), see Figures 3(c) and 4. We propose that the approach developed in this study could be applied to further understand the large discrepancies in reports of mechanical behaviour of bone tissue between different experimental test methods (Runkle and Pugh 1975;Townsend et al 1975;Mente and Lewis 1989;Ryan and Williams 1989;Choi et al 1990;Rho et al 1993;Samelin et al 1996;Rho et al 1997;Rho et al 1998;Rho et al 1999;Zysset et al 1999;Hoffler et al 2000;Ferguson et al 2003;McNamara et al 2006a;Ozcivici et al 2008;McNamara 2011), but also to decipher the impact of changes in tissue composition or structure during disease. From the results presented here, it is clear that a major contributor to this large range of experimentally reported stiffness values is the MVF (Figures 3 and 5).…”

“…Mechanical testing of trabecular and cortical bone tissue has been carried out using 3/4-point bending (Choi et al 1990), buckling (Runkle and Pugh 1975;Townsend et al 1975), cantilever beam tests (Mente and Lewis 1989), micro-tensile testing (Ryan and Williams 1989;Rho et al 1993;Samelin et al 1996;McNamara et al 2005;McNamara et al 2006a), ultrasonic measurement (Rho et al 1993) and nanoindentation (Rho et al 1997;Rho et al 1999;Zysset et al 1999;Hoffler et al 2000;Ferguson et al 2003;Ozcivici et al 2008).…”

“…Reported values for the elastic modulus of trabecular and cortical tissue from these studies have conflicted, with values ranging from 0.75GPa to 30GPa (Runkle and Pugh 1975;Townsend et al 1975;Mente and Lewis 1989;Ryan and Williams 1989;Choi et al 1990;Rho et al 1993;Samelin et al 1996;Rho et al 1997;Rho et al 1998;Rho et al 1999;Zysset et al 1999;Hoffler et al 2000;Ferguson et al 2003;McNamara et al 2006a;Ozcivici et al 2008;McNamara 2011). There is much contention regarding whether cortical and trabecular bone are fundamentally the same tissue, and that it is their tissue organisation that distinguishes their mechanical behaviour, or whether the tissue composition and mechanical properties are different between the two bone types.…”

“…The bounding functions (W ¼ 0 and W ¼ 1) were based upon ultrasonically measured moduli from normal, human cancellous and cortical bone specimens from different anatomic sites. 12 Osteoporotic bone was not modeled, because patients with this disease would generally be poor candidates for hip resurfacing. 2 The bounding functions were determined as follows.…”

Hip resurfacing increases bone strains associated with short‐term femoral neck fracture

Short-term femoral neck fracture is a primary complication associated with contemporary hip resurfacing. Some fractures are associated with neck notching, while others occur in the absence of notching. These unexplained fractures may be due to large magnitude strains near the implant rim, which could cause bone damage accumulation and eventual neck fracture. We used statistically augmented finite element analysis to identify design and environmental variables that increase bone strains near the implant rim after resurfacing, and lead to strain magnitudes sufficient for rapid damage accumulation. After resurfacing, the compressive strains in the inferior, peripheral neck increased by approximately 25%, particularly when the implant shell was bonded. While the tensile strains in the peripheral neck were low in magnitude in the immediate postoperative models, they increased substantially following compressive damage accumulation. Low bone modulus, within the range of normal bone, and high head load contributed the most to large magnitude strains. Therefore, in some cases, hip resurfacing may cause a region of compressive bone damage to develop rapidly, which in turn leads to large tensile strains and potential neck fracture. Our study suggests that indications for surgery should account for bone material quality, and that rehabilitation protocols should avoid high-load activities. ß

“…This is due to differences in research methods, methods of sample preparation etc. Most researchers conclude that the elastic modulus of trabecular bone is 20-30% lower than the elastic modulus of cortical bone [20][21][22]. Nevertheless, several authors argued that elastic modules of the cortical and trabecular bone tissues are identical or differ insignificantly [23,24].…”

This article presents new intramedullary (IM) nail design for femur diaphyseal fractures osteosynthesis. Biomechanical comparison of the two IM nails (standard locking and new developed) was conducted. Femur medullary canal architectonics was studied with the help of computer tomography (CT) data. Three-dimensional (3D) models of the femur, its transverse fracture, standard locking nail and new developed nail were constructed as well as the bone-implant system models. Stress-strain state of the bone-implant systems under three types of loads (axial, lateral and torsional) was studied using finite-element method in commercial software Ansys 14.0. Numerical results showed that new nail allows proximal fragment of the bone to move in an axial direction. New nail provides necessary compression at fragments junction. It was revealed that the highest values of effective stress (ES) for the standard nail were concentrated at contact area between locking screws and nail for all investigated loads. For the new nail the highest values of ES were concentrated on its body and blades at proximal region. Moreover, stresses occurred in the new nail were smaller than stresses appeared in the standard nail. This conclusion is valid for three investigated types of loads. So the new nail does not have serious disadvantages of standard nails. From the biomechanical point of view the new nail is more preferable for diaphyseal femur fractures osteosynthesis.
